Spring practices are now underway at college football programs across the country.
FBS head coaches everywhere are preparing for a season that is still nearly six months away.
No matter how good a team is, it's almost certain to run into some problems during the spring that it hopes won't carry over into the regular season. That is the best thing about spring practice; it's a chance for a head coach to get a look at his team and see just what he's working with.
As with any type of practice, there will be issues that arise for head coaches.
Here is the biggest headache each of the 125 FBS head coaches is facing as spring practice begins.
Biggest headache: Dealing with new pregame rituals
Air Force head coach Troy Calhoun certainly has plenty of issues to deal with on the field, but there's also one developing off of it.
According to the Washington Post, there won't be any more flyovers at football games.
This may not seem like a big deal, but at a university like Air Force it's more important than some might think.
Biggest headache: Winning a game in the MAC
Akron has been one of the worst teams in the country over the past few seasons, and head coach Terry Bowden will have his hands full once again.
His biggest headache heading into the spring will be finding a way to get out of the basement in the MAC.
The Zips failed to win a league game last year, which has likely been on Bowden's mind all offseason.
Biggest headache: Making sure players stay out of trouble
What in the world could Alabama head coach Nick Saban have to worry about? He has the most talented team in the country and is looking for a fourth national championship in five years.
Texas A&M quarterback Johnny Manziel might already be a headache for Saban with the way he is, but the biggest problem for Saban heading into the spring will be making sure to keep his players out of trouble.
Biggest headache: Developing a defense
Defense is almost a lost art in college football, as is the case at UAB. The Blazers ranked No. 114 in the country last season, allowing 37.5 points per game.
Second-year head coach Garrick McGee will be trying to figure out a way to develop a unit that was relatively young a season ago.
One of the main reasons for the team's struggles was their awful defense. McGee will be trying to turn that around.
Biggest headache: Replacing quarterback Matt Scott
Rich Rodriguez will be entering his second season running the Arizona program, and while last season his biggest headache was adjusting to a new system, this year it will be replacing quarterback Matt Scott.
While searching for a quarterback isn't necessarily a headache, it could be if he doesn't find the right one.
There are three potential candidates for the starting spot, including USC transfer Jesse Scroggins and backup B.J. Denker. True freshman Anu Solomon could also be a factor.
Another headache for Rodriguez will be keeping running back Ka'Deem Carey out of trouble, as he has faced some off-the-field issues over the past few months.
Biggest headache: Finding offensive line replacements
Arizona State is getting plenty of starters back on offense, but one position with some spots up for grabs is the offensive line.
Andrew Sampson and Brice Schwab have departed and won't be easy to replace.
Head coach Todd Graham needs to make sure he picks the right players for these open spots.
Biggest headache: Learning how to transition into the SEC
New Arkansas head coach Bret Bielema may be in for a rude awakening after bolting Wisconsin to take over the Arkansas job.
He ran a Badgers offense that pounded the football and had a lot of success doing it.
Things may not be that easy in the SEC, but Bielema has all spring to figure out how to succeed in a new division.
Biggest headache: Transitioning to a head coach
Bryan Harsin takes over the Arkansas State job after serving on Mack Brown's staff as the offensive coordinator the past two seasons.
This will be his first head coaching job, and he is taking over a program that has very high expectations.
Red Wolves fans are not going to accept losing, so Harsin will need to transition quickly as a head coach.
Biggest headache: Finding a replacement for Trent Steelman
Army quarterback Trent Steelman had quite a career for the Black Knights and he won't be easy to replace.
Head coach Rich Ellerson has plenty of time to find a replacement and it all starts at spring practice.
Sophomore A.J. Schurr might be the leading candidate, but there is still a long way to go in this battle.
Biggest headache: Adjusting to big-time college football
Gus Malzahn spent the 2012 season as the head coach of the Arkansas State Red Wolves. While he had a successful 9-3 season, he is going to reach a whole new level at Auburn.
The Tigers only won three games last season, so expectations may not be very high.
That doesn't mean Malzahn won't be facing some pressure this season.
Biggest headache: Improving defensively
Ball State had a very successful 2012 season, finishing the year 9-4 with a bowl loss to Central Florida.
The offense was very explosive, but head coach Pete Lembo and his team struggled defensively.
The group allowed 32 points per game and didn't hold an opponent under 22 points until the bowl victory over UCF.
Improvements are needed on defense for 2013.
Biggest headache: Replacing Nick Florence
Baylor head coach Art Briles has had some pretty talented quarterbacks over the past few years, and even though he lost Robert Griffin III early to the NFL draft after the 2011 season, he had a viable replacement in senior Nick Florence.
Now Florence is gone and it is time to find another quarterback.
The battle will begin with spring practice. The leading candidates appear to be junior Bryce Petty and freshman Seth Russell.
Biggest headache: Finding a way to win the season opener
Boise State has been playing big-name teams in its opening games the last few seasons. This time the Broncos will take on a Washington team that they defeated in the Las Vegas Bowl in December.
If head coach Chris Petersen and his team have any plans to make a splash on the national scene, they will need to find a way to get by Washington.
There is enough returning talent to do just that.
Biggest headache: Getting Boston College out of the basement in the ACC
There are few FBS teams who've been worse over the past few seasons than Boston College. The Eagles struggled to a 2-10 campaign last year.
New head coach Steve Addazio is coming over from Temple, where he had some success over the past few seasons.
Now, turning around the Boston College program will be a whole new task.
Biggest headache: Finding some offensive firepower
Bowling Green was a bit of a surprise last year, winning eight games, including six victories in the MAC.
They were a team that did it with defense. The Falcons had one of the best units in the country, and to better that record in 2013 head coach Dave Clawson and his squad will need to improve defensively.
Finding a few players to plug the open spots will be Clawson's biggest concern this spring.
Biggest headache: Replacing defensive playmakers
BYU head coach Bronco Mendenhall is entering his ninth season as the head coach of the program and has another solid squad.
Last season the defense ranked third in the nation, allowing only 14 points per game. In 2013, Mendenhall will need to replace some key starters, including defensive end Ezekial Ansah, cornerback Preston Hadley and linebacker Brandon Ogletree.
The good news for Mendenhall is Kyle Van Noy will return for his senior season.
Biggest headache: Finding some offensive firepower
Buffalo Bulls head coach Jeff Quinn will be entering his fourth year as head coach, and while the Bulls have improved, there is still a long way to go.
A lot of improvements can be made on offense. The group ranked No. 101 in the country last season, averaging only 21.3 points per game. The defense was average, but Quinn has an offensive mind and is going to have to find a way to improve his squad in order to move out of the bottom half of the MAC.
Biggest headache: Recovering from last season
California head coach Sonny Dykes is taking over a team that struggled in 2012.
The Bears only went 3-9 a year ago, and there is no question that last season's record will be on his mind as spring practice kicks off.
His squad struggled on both sides of the ball a year ago, ranking near the bottom of the country in both points scored and points allowed.
His headache might go away with a few wins early in the season.
Biggest headache: Transitioning to a new league
While stepping into the Big East is nowhere close to moving into the SEC, there is no doubt that the conference is still a step up for a team like Central Florida.
The Knights were one of the best teams in Conference USA over the past few seasons, but that's not likely to be the case anymore.
Head coach George O'Leary will be spending the spring and summer learning about some new opponents and trying to prepare his team for a more challenging schedule in 2013.
Biggest headache: Finding some defensive help
Central Michigan came on strong at the end of last season, winning its final four games to finish 7-6.
The strength of the team was the offense, and head coach Dan Enos will be looking to improve on a defense that ranked No. 96 in the country and allowed 32.4 points per game.
That defense did improve toward the end of the year, allowing just over 22 points per game in the final four games.
Biggest headache: Finding defensive line replacements
New Cincinnati Bearcats head coach Tommy Tuberville not only has to acclimate to a new team, he'll have to find some new starters, particularly at defensive end.
Cincinnati loses Walter Stewart, Dan Giordano and Brandon Mills. All three players were fifth-years seniors that saw ample playing time at defensive end over the past four seasons.
They'll be hard to replace, but Tuberville now has six months to find some viable replacements.
Biggest headache: Replacing offensive playmakers
Clemson head coach Dabo Swinney has been blessed with an immense amount of talent, particularly on offense.
In 2013, he'll have to replace some key playmakers, including running back Andre Ellington and wide receiver DeAndre Hopkins.
It might take more than two guys to make up for the loss of those players, but there are enough playmakers coming back for Clemson to be a contender in the ACC.
Biggest headache: Finding a way to win in Boulder
New Colorado Buffaloes head coach Mike MacIntyre will have his hands full taking over a program that has been as bad as it gets in recent years.
The Buffaloes only won one game last year and were statistically one of the worst teams in the country.
He will have to find a way to improve a defense that allowed 46 points per game last year, good for No. 124 in the country.
Biggest headache: Finding their offense
Colorado State only won four games last year and part of that was due to a lack of offense. The Rams only scored 21.2 points per game, good for No. 102 in the country.
Head coach Jim McElwain did use freshman Conner Smith the last six games of the season at the quarterback position and the Rams won three of those.
The development of Smith will be huge and is something that needs to happen if the Rams want to improve on their 4-8 record.
Biggest headache: Finding a quarterback
One of the main reasons Connecticut only averaged 17.8 points per game last season was because of poor quarterback play.
The Chandler Whitmer-Johnny McEntee combination threw for only 10 touchdowns with 18 interceptions.
Whitmer will return for his junior season along with third-stringer Scott McCummings.
Head coach Paul Pasqualoni needs more production from the QBs in 2013.
Biggest headache: Keeping momentum from last season
Even though Duke won six games a year ago and qualified for a bowl game, the season didn't end the way head coach David Cutcliffe would've liked.
Duke lost its final five games of the season to finish the year 6-7.
To reach a bowl game again in 2013, the Blue Devils must get off to a good start. Cutcliffe certainly has to be focused on that heading into spring practice.
Biggest headache: How to beat the ACC
East Carolina head coach Ruffin McNeil and his Pirates will have their hands full with ACC teams in the non-conference portion of the schedule.
The Pirates take on the likes of Virginia Tech, North Carolina and North Carolina State outside of the Conference USA slate.
There is no question that McNeil has been worried about those ACC teams since the schedule was released.
Biggest headache: Developing a passing game
Eastern Michigan was one of the bottom feeders in the MAC last season, finishing the year 2-10 and 1-7 in league play.
The quarterback position was the sour point, as the combination of Tyler Benz and Alex Gillett only threw for 2,054 passing yards on the season.
As one of the worst passing teams in the country, the Eagles didn't have the firepower to come from behind against anybody.
Benz will be back for his junior season, but improvements will be needed.
Biggest headache: Can Jeff Driskel turn the corner?
Florida was one of the most complete teams in the country last season, but struggled for most of the year at the quarterback position.
Jeff Driskel will be back for his junior season, and if the Gators plan on contending for the national championship, they'll need him to step up big.
Muschamp didn't show much confidence in Driskel in 2012 and is undoubtedly worried about his quarterback situation heading into the 2013 campaign.
Biggest headache: How to develop a running game
Florida Atlantic ranked No. 110 in the country last season, averaging only 112.3 yards rushing per game.
Head coach Carl Pelini and his squad are making the jump to Conference USA and hopefully for them, the going gets a little easier in a league where points come rather easily.
Jonathan Wallace will be back for his senior season. He was the leading rusher last year, totaling 668 yards and six scores.
Pelini is going to need much more production from his running game to win more than the three games he won in 2012.
Biggest headache: Transitioning back from the NFL
New Florida International head coach Ron Turner will be taking over after spending the past few seasons as a quarterbacks coach in the NFL with the Indianapolis Colts and Tampa Bay Buccaneers.
The Panthers are another team that is moving into Conference USA after a three-win campaign in 2012.
There may be an adjustment period, but this team appears to be headed in the right direction with the hiring of Turner.
Biggest headache: Moving on from E.J. Manuel
Florida State has had some talented quarterbacks over the past few seasons, including Christian Ponder and E.J. Manuel.
Manuel has now moved on and Jimbo Fisher is in the process of finding his replacement.
The leading candidate may be junior Clint Trickett, but redshirt freshman Jameis Winston is without question the most talented player in the mix.
Fisher will have a big decision to make and it all starts with spring practice.
Biggest headache: Finding offensive balance without Robbie Rouse
Fresno State featured a very balanced offensive attack last year with running back Robbie Rouse and quarterback Derek Carr leading the way.
Rouse has now moved on and as he prepares for the NFL draft, head coach Tom DeRuyter is trying to find his replacement.
No other player on the team carried the ball more than 41 times last season, so it's going to be a process finding a replacement for Rouse.
Biggest headache: Getting over the hump
Georgia has been very close the past few years and was a few seconds away from playing Notre Dame in the national title game.
To be that close two years in a row and come up short could be very disheartening for head coach Mark Richt and his squad.
Finding a way to get over the mental hump is going to be the toughest battle for Richt and the Bulldogs, as the talent is there to compete with anybody in the country in 2013.
Biggest headache: Finding someone to replace Tevin Washington
Georgia Tech is a triple-option offense that ran smoothly with Tevin Washington under center the past few years, but he is no longer in the program and head coach Paul Johnson will need to find a viable replacement.
The favorite to take over the job is sophomore Vad Lee, but there are other names in the mix like Justin Thomas and incoming freshman Ty Griffin.
While there is talent in the group, running the triple-option offense is no easy task.
Biggest headache: How to transition to the FBS level
Georgia State is experiencing a lot of change. The Panthers are joining a new conference in the Sun Belt, have a new head coach in Trent Miles and will also be playing their first season at the FBS level.
Miles spent the past five seasons as the head coach of Indiana State, leading the Sycamores to a 20-36 overall record, but a 19-14 mark over the final three seasons.
The schedule is very challenging, with games against West Virginia and Alabama outside of conference. More than a win or two would be very surprising for the Panthers in 2013.
Biggest headache: How to win enough games to keep job
Norm Chow has had an excellent career as a football coach all over the map, but his Hawaii Warriors struggled mightily last season, winning only three games.
Kicking off the season with games against USC and Oregon State, it isn't looking promising for Hawaii in 2013.
The team was as bad as almost anybody in the country on both sides of the ball last year, so Chow might be in a fight to keep his job this coming season.
Biggest headache: Improving a very weak defense
Houston won't only be moving to the Big East in 2013, they'll also be trying to improve on a defense that allowed 36 points per game last season.
Head coach Tony Levine and his Cougars struggled in his first season, winning only five games in 2012.
It seems like they are still trying to recover from the loss of former head coach Kevin Sumlin and former quarterback Case Keenum, but that still doesn't explain the poor defensive play in 2012.
Biggest headache: Making the program relevant
Idaho is one of the least known football programs in the country and now that the WAC is no longer around, the Vandals are an independent team for the time being.
They're also welcoming a new head coach in Paul Petrino.
He is the younger brother of Bobby Petrino and will have his hands full trying to make Idaho relevant to anybody willing to take a liking to the team.
Biggest headache: Finding an offensive attack
Illinois has been awful the past few seasons and most of that is due to having one of the worst offenses in the country.
The Fighting Illini only averaged 16.7 points per game last season, one of the worst marks in the country.
The problems began at the quarterback position with Nathan Scheelhaase; the junior only threw four touchdown passes the entire season with eight picks.
Improved play is needed at QB in the worst way.
Biggest headache: How to improve on the success of 2012
While a 4-8 record isn't exactly success, the Indiana Hoosiers controlled their own destiny with three weeks left in the season. Unfortunately, they lost all three games after winning two in a row.
Head coach Kevin Wilson now has an opportunity to build on the success of the 2012 year and maybe get the Hoosiers in the bowl conversation.
That's certainly easier said than done when it comes to football in Bloomington.
Biggest headache: Getting over the disappointment of 2012
There were plenty of disappointments during the 2012 college football season, but near the top of the list are the Iowa Hawkeyes.
After starting the season 4-2, the Hawkeyes lost six straight games to finish the year 4-8; not exactly what head coach Kirk Ferentz was looking for. Another season like that and he might find himself on the hot seat.
It's his job to forget about last season and move forward.
Biggest headache: How to replace the linebacker group
Iowa State had some very talented linebackers last season and head coach Paul Rhoads is going to have his hands full replacing Jake Knott and A.J. Klein.
Knott and Klein have moved on to the NFL draft and will be sorely missed.
The Cyclones have had some success over the past few years, but the defense will be missing their presence in the middle this year.
That has to be worrying Rhoads as spring practice begins.
Biggest headache: Trying to win a Big 12 game
Kansas head coach Charlie Weis certainly struggled in his first season as the head coach at Kansas and it doesn't look like things are going to get any easier.
The Jayhawks failed to win a league game in 2012. If there's a repeat performance of that in 2013, Weis will likely find his way out the door.
He is bringing in a lot of JUCO transfers to try to win right now, but the talent level may not be there to compete against Big 12 competition.
Biggest headache: Replacing Collin Klein
Kansas State head coach Bill Snyder is tasked with replacing one of the most valuable players in the country in quarterback Collin Klein.
Few players were more valuable to their team than Klein in 2012; he nearly led Kansas State to the national title game.
It's going to be weird watching the Wildcats without Klein running the show in 2013.
Snyder will have to find a viable replacement. Sophomore Daniel Sams appears to be the front-runner.
Biggest headache: How to fill Darrell Hazell's shoes
Paul Haynes is taking over a Kent State team that won 11 games last year and was undefeated during the regular season of MAC play.
Former head coach Darrell Hazell is leaving big shoes to fill and it's hard to tell whether Haynes will be up to the task.
There is enough talent coming back for him to be successful, but Hazell did quite a job turning the program around in his two seasons at Kent State.
Biggest headache: How to make football relevant at Kentucky
Mark Stoops is taking over a Kentucky job that is one of the most challenging in the entire SEC.
That said, he is one of 14 coaches fortunate enough to be running an SEC program.
He did put together the best recruiting class in the history of the program.
While it certainly won't be something that happens overnight, Stoops appears to be on the right track with the Wildcats.
Biggest headache: Replacing defensive starters
LSU will no doubt reload, but the Tigers have to replace plenty of talent on a defense that was one of the most feared in the SEC last season.
With early departures to the NFL across the board on defense, the Tigers won't be nearly as talented in 2013.
Head coach Les Miles will need to find the perfect replacements, and that all begins with spring practice. We all know there is enough talent there for him to choose from.
Biggest headache: Replacing Colby Cameron
Besides welcoming new Louisiana Tech head coach Skip Holtz, the Bulldogs are undergoing plenty of other change; they'll be entering their first season in Conference USA and doing so without the very talented quarterback Colby Cameron, who graduated.
Holtz had his struggles at South Florida, but he's getting a second chance at Louisiana Tech. His first task, and perhaps the most important, will be choosing the right quarterback to replace Cameron.
Biggest headache: Getting off to a good start
Louisiana-Lafayette head coach Mark Hudspeth led his team to a 9-4 campaign and a bowl victory in 2012.
There is a lot of talent coming back, but that record is going to be tough to duplicate with the difficult schedule, especially at the beginning of the season.
The Rajin' Cajuns take on Arkansas and Kansas State to kick off the year, both of which are road.
Biggest headache: Playing with a target on their back
Louisiana-Monroe was a bit of a surprise last season as the Warhawks won eight games. They managed to beat Arkansas and only barely lost to Baylor.
They snuck up on a lot of teams, and that won't be the case in 2013.
With tough non-conference games against Oklahoma, Wake Forest and Baylor, the Warhawks will have a target on their back, even from the bigger schools.
That is certainly the biggest concern for head coach Todd Berry heading into the season.
Biggest headache: How to live up to expectations
The Louisville Cardinals will be playing their final football season in the Big East in 2013, and there's no question that they will be a heavy favorite to win the league.
Head coach Charlie Strong led his team to a Sugar Bowl victory this past season, and there is talent returning all over the field, including quarterback Teddy Bridgewater.
There is going to be a lot of pressure on Louisville to live up to lofty expectations and win the Big East. Dealing with that pressure is the biggest concern right now for Strong.
Biggest headache: Finding their defense
There's no doubt that Marshall had one of the most explosive offenses in the country in 2012, averaging over 40 points per game.
The defense, on the other hand, was a completely different story, as the Thundering Herd allowed over 43 points per game, ranking No. 123 in the country.
Head coach Doc Holliday has the unenviable task of trying to find enough talent on his squad to field a reputable defense.
If he can do that, the 5-7 mark from a year ago can certainly be improved upon.
Biggest headache: Staying healthy
No team in the country was decimated by injuries at one position more than the Maryland Terrapins in 2012.
Head coach Randy Edsall saw his four quarterbacks all go down to injuries, eventually resorting to playing a freshman linebacker who played QB in high school.
That is about as bad of luck as it gets, and while it's definitely unlikely to happen again, it has to be in the back of Edsall's mind as spring practice gets underway.
Biggest headache: How to compete at the FBS level
The 2012 season was the first at the FBS level for a Massachusetts team that went 1-11 a year ago with its only win coming against Akron.
Head coach Charley Molnar will be looking to improve on that mark, and it appears there is plenty of talent on the roster to win a few more games in 2013.
Regardless, Molnar enters spring practice trying to figure out how to get his team out of the bottom of the MAC.
Biggest headache: Competing in the Big East
Memphis struggled mightily last season under first-year head coach Justin Fuente, finishing 4-8 with a 4-4 record in Conference USA.
Now they are moving to the Big East, and the schedule is going to be a lot more challenging.
Head coach Justin Fuente will have his hands full in 2013 as the Tigers will be taking on the likes of Cincinnati, Louisville, Rutgers and Connecticut.
Not exactly the SEC, but not Conference USA either.
Biggest Headache: Keeping his team focused
As the NCAA continues to investigate Miami, head coach Al Golden will need to keep his team focused amidst the madness.
Miami wasn't eligible for a bowl game last year, but in 2013 there is going to be some talented young players ready to compete for the ACC title.
If Golden can keep his players' heads in the game and away from what's outside of their control, this is going to be a very successful team in 2013.
Biggest Headache: Replacing Zac Dysert
Miami head coach Don Treadwell was blessed with a very talented quarterback over the past few seasons in Zac Dysert.
Dysert threw for 73 touchdowns during his four years as the starter at Miami and will be missed as much as almost any player in college football.
Finding a replacement for him is no easy task, as it'll be hard for whoever is chosen to live up to expectations.
Treadwell must make the right decision in spring practice.
Biggest headache: Moving on without Denard Robinson
Even though Denard Robinson wasn't the starting quarterback by the end of the season, he was still one of the biggest playmakers on the field for the Wolverines.
The guy did a little bit of everything for Michigan over the past four seasons and he'll be sorely missed.
It looks like Devin Gardner will be the permanent quarterback, but there will still times when Michigan fans miss Robinson in 2013.
Biggest headache: Finding offensive playmakers
Michigan State struggled to a 7-6 campaign in 2012, due in a large part to their offense.
Things may be even more difficult in 2013 with running back Le'Veon Bell moving on early to the NFL draft.
There aren't a lot of playmakers on the Spartans roster, and head coach Mark Dantonio is going to have to find a few diamonds in the rough if he plans on putting more points on the board than he did a season ago.
Biggest headache: Transitioning to a new conference
The Middle Tennessee Blue Raiders will be entering their first season in Conference USA and they'll be doing so with an experienced head coach.
Rick Stockstill has been with the program since 2006, when the Blue Raiders began to develop into one of the powers of the Sun Belt conference.
They have the pedigree to do the same in Conference USA, but 2013 might be a bit of a transition year for this team.
Biggest headache: Figuring out how to duplicate last season's success
Minnesota had struggled in recent seasons until an impressive 2012 campaign resulted in a bowl berth.
Even though the Gophers struggled down the stretch, some early-season wins enabled them to sneak into a bowl game at 6-6.
Head coach Jerry Kill will need to try to find a way to duplicate the success his team had last season.
That is easier said than done with the squad he has coming back.
Biggest headache: Living up to the expectations
Ole Miss head coach Hugh Freeze put together quite a recruiting class, potentially raising expectations for the Rebels to achieve more in 20123 than it is capable of.
Even though the recruiting class is very talented, it's still a very young squad, and it is the SEC after all.
The schedule is not doing the Rebels any favors with road games against Vanderbilt, Texas and Alabama before the end of September and Texas A&M and LSU in October.
Biggest headache: Keeping up with in-state rival Ole Miss
Mississippi State head coach Dan Mullen has to be wondering just how in-state rival Ole Miss put together their impressive recruiting class.
The two teams were virtually evenly matched last season and that might be the case again in 2013, but with the young talent on the Rebels, it may not be that way for too long.
Mullen has the Bulldogs headed in the right direction, but they may become second-fiddle in the state of Mississippi.
Biggest headache: Keeping James Franklin healthy
Missouri struggled in its first season as a member of the SEC, winning only five games, but a lot of that was due to injuries at key positions like quarterback.
James Franklin was in and out of the lineup last season—the main difference between a bowl team to and one who comes up just short.
Head coach Gary Pinkel will need to keep his quarterback healthy to put together a winning season.
Biggest headache: Finding a replacement for Gee Gee Greene
Navy is one of those teams that runs a triple-option offense, and the leading rusher from a year ago, Gee Gee Greene, has graduated.
He only carried the ball 120 times, but managed 877 yards while averaging 7.3 yards per carry with three scores.
There is plenty of talent coming back on offense for the Midshipmen, but Greene brought a dynamic that will be hard to duplicate in 2013.
Biggest headache: Improving defensively
The Nebraska defense was nowhere close in 2012 to what fans are used to.
The unit allowed 27.6 points per game and struggled heavily toward the end of the season, giving up 115 points combined in the final two games of the year.
Most of the starters are gone, but that might not be a bad thing. With only four starters returning, the group is certainly going to be young this coming season.
Biggest headache: Succeeding as a first-year head coach
Brian Polian is another first-year head coach taking over a program that has been successful in recent years.
Polian was the special teams coordinator last season for Texas A&M, and this is his first head coaching job at any level.
Look for there to be an adjustment period for Polian and the Wolf Pack.
Biggest headache: Finding enough talent to win a few games
UNLV was one of the worst teams in the country last season, going 2-11 and being dominated in the Mountain West conference.
The Rebels struggled on both sides of the ball last year, finishing at No. 97 in both points scored and points allowed.
Head coach Bobby Hauck will have his hands full trying to clean up this mess.
Biggest headache: How to improve on last year's success
Even though New Mexico only won four games a season ago, that was an improvement for the Bob Davie-led Lobos.
Davie will be entering his second season running the program, and the Lobos look to be even better in 2013.
There are some winnable games at the beginning of the season as the Lobos look to improve on last year's record.
Biggest headache: Finding out how to win a game
New Mexico State was probably the worst FBS team last season, and now first-year head coach Doug Martin will take over an awful program without a conference.
The only win last year for the Aggies came in the season opener against Sacramento State; New Mexico State lost every other game by at least eight points.
Martin did get a head coaching job, but perhaps one of the the most challenging jobs in the country.
Biggest headache: Replacing Giovani Bernard
North Carolina head coach Larry Fedora has plenty of offensive talent returning, but he'll have to find a replacement for star running back Giovani Bernard.
Bernard led the ACC in rushing, scoring, all-purpose yards and punt return average.
The battle to replace him will feature Romar Morris and A.J. Blue. Fedora will need to make the right decision, as the season could hinge on the play from the running back position.
Biggest headache: Finding a quarterback
North Carolina State has been blessed with talented quarterbacks the past few years, including Russell Wilson and Mike Glennon.
This season, first-year head coach Dave Doeren has plenty of big decisions to make, but perhaps the most important is selecting a starting quarterback.
Manny Stocker and Pete Thomas are battling for the starting job, and Doeren will have his hands full picking the right one.
Biggest headache: Improving on offense
North Texas head coach Dan McCarney not only has to transition into a new conference as the Mean Green moves from the Sun Belt to Conference USA, but he also has to deal with an offense that struggled mightily in 2012.
The Mean Green only averaged 20.9 points per game, good for No. 105 in the country.
There are plenty of skill position players coming back, but McCarney and his group have a lot of work to do in order to improve on offense.
Biggest Headache: Avoiding an Orange Bowl hangover
Even though Northern Illinois was dominated by a much more talented Florida State team in the Orange Bowl, that doesn't mean it wasn't a successful season.
New head coach Rod Carey will need to try and make sure his team avoids an Orange Bowl hangover.
Quarterback Jordan Lynch will be back and so will a lot of other talented players on a team that needs to forget about how last season ended.
Biggest headache: Winning with a bulls-eye on their back
Northwestern snuck up on a lot of teams last season, finishing the year 10-3 overall and 5-3 in league play.
This year could be a completely different story, as the Wildcats are going to have a big target on their back.
Northwestern is no longer the laughing stock of the Big Ten and is now a serious threat. Pat Fitzgerald will have to deal with the fact that everybody knows it.
Biggest headache: Moving on from the national championship debacle
Notre Dame head coach Brian Kelly orchestrated quite a season in 2012, but the year didn't end as he or the Fighting Irish hoped.
Kelly will need to make sure his team has forgotten about the loss to Alabama two months ago and spring practice is the first chance for the Fighting Irish to start to get the bad taste out of their mouths from the national championship game.
Biggest headache: Finishing the season strong
Ohio came out of the gates like a ball of fire last year, winning their first seven games of the year, including a victory in the season opener over Penn State that vaulted them into the Top 25.
But the end of the season was downright awful as the Bobcats lost four of their final five regular-season games before knocking off Louisiana-Monroe in the Independence Bowl.
Head coach Frank Solich has the talent to contend in the MAC and will need to find a way to finish the season strong this time around.
Biggest headache: Finding D-line replacements
Urban Meyer led Ohio State to a perfect 12-0 season during his first year as the head coach of the Buckeyes.
He has a lot of talent coming back, but he loses all four starters along the defensive line.
Replacing those guys won't be an easy task, but there are plenty of youngsters who have the talent to step in and shine.
Meyer will have the opportunity to pick from a number of those skilled players.
Biggest headache: Can Blake Bell succeed?
Landry Jones has graduated and now it appears that Blake Bell will take over the starting quarterback job.
The competition is still open, but Bell seems to be the front-runner. Over the past few years, Bell has shined, but almost exclusively in goal-line running situations.
It's still a big concern whether or not he can pass the ball well enough to succeed for the Sooners.
Head coach Bob Stoops will see what this kid can do this spring.
Biggest headache: Picking a quarterback to lead his team
While having a few talented quarterbacks is certainly not something to be bothered with, Oklahoma State head coach Mike Gundy will definitely have his hands full this spring trying to decide who to select as his starting quarterback.
There are three players who are in the mix for the starting job and all three bring something to the table.
Wes Lunt, J.W. Walsh and Clint Chelf are all relatively young and very talented. This competition is wide-open and could be one of the best spring battles in the country.
Biggest Headache: Escaping from Chip Kelly's Shadow
New Oregon head coach Mark Helfrich is a very familiar name as he has served as the offensive coordinator for the past four seasons in Eugene.
He knows the personnel, so it should be a smooth transition for everyone involved.
However, he will be replacing one of the most successful coaches college football has ever known.
Making Oregon fans forget about Chip Kelly is not going to be easy to do.
Biggest headache: Choosing the right quarterback
Like a few other coaches, Oregon State head coach Mike Riley will have a quarterback decision of his own to make.
He only has two guys to choose from, but both offer something a little different.
Senior Cody Vaz and junior Sean Mannion both saw plenty of action last season, and the two will be going head-to-head this spring.
Riley will have an important decision to make come spring practice.
Biggest headache: Keeping fans interested
Even though Penn State had a very successful season in 2012, the Nittany Lions won't be bowl-eligible for three more years.
The energy level last season was very good, but the team was playing with a lot of emotion.
Head coach Bill O'Brien will need to find a way to keep the energy in the program. If he can do that, this team has a chance to be a factor in the Big Ten.
Biggest headache: Finding offensive playmakers
Second-year Pittsburgh head coach Paul Chryst took over the program in 2012 with some key players returning.
That's not the case entering his second season, as he lost quarterback Tino Sunseri, running back Ray Graham and wide receiver Mike Shanahan.
Chryst will have to find some players to help fill the void left by this talented trio of seniors.
Biggest headache: How to improve a very weak defense
New Purdue head coach Darrell Hazell will be inheriting a defense that ranked No. 89 in the country in points per game, allowed over 31 points per game last season.
Hazeel is coming from a Kent State team that only allowed 24.5 points per game last season.
Hazell will have his work cut out for him to improve this defense, particularly with star defensive tackle Kawann Short having moved on to the NFL draft.
Biggest headache: How to slow down Johnny Manziel
Rice came on strong at the end of last season, winning its final five games to finish 7-6.
This year the first game of the season comes on the road against Texas A&M.
Rice head coach David Bailiff is certainly already trying to come up with a plan to stop Heisman Trophy winner Johnny Manziel, and he has all spring and summer to do so.
Biggest headache: Replacing Jawan Jamison
Rutgers head coach Kyle Flood certainly didn't know for sure that running back Jawan Jamison would leave early for the NFL draft, but he decided to bolt and now the Scarlet Knights will likely struggle even more on offense.
The Scarlet Knights had enough trouble scoring last season, averaging only 21.5 points per game, and it may not get any easier in 2013.
Defense, however, will not be a problem.
Biggest headache: How to deal with a challenging non-conference slate
San Diego State has always been very competitive and that should be the case once again in the Mountain West conference.
The Aztecs will have two talented opponents to help prepare for conference play, as a road trip to Columbus to take on Ohio State looms as the second game of the year, followed by a home game against Oregon State.
Finishing last year with nine wins, it’s hard to imagine head coach Rocky Long and his squad having too much difficulty this season.
Biggest headache: Moving to a better conference
San Jose State is a very talented football team and welcomes a new head coach in Ron Caragher.
They'll also be playing in a new conference, one that will be much more competitive than their previous home in the WAC.
The Spartans are joining the Mountain West with the likes of Boise State, Fresno State, San Diego State, Utah State and Nevada.
This will be a very competitive league, and the Spartans could be right in the mix.
Biggest headache: Improving offensively
South Alabama will be entering its second year at the FBS level after only winning two games a season ago.
The Jaguars struggled on offense as the team only averaged 18.5 points per game; head coach Joey Jones needs to find playmakers on that side of the ball.
The schedule is not going to do his team any favors as Kent State, Navy and Tennessee appear out of conference along with some talented teams in the Sun Belt.
Biggest Headache: Jadeveon Clowney staying healthy
USC has a few issues to worry about, including replacing star running back Marcus Lattimore, but the Gamecocks have proven capable of being able to do just that.
While the health of star defensive end Jadeveon Clowney might not have a huge effect on the team this season, if he does go down with a major injury, head coach Steve Spurrier will certainly feel sick to his stomach.
It was mentioned at one point that it could be beneficial for Clowney to sit the season out, but Spurrier laughed at that notion.
Biggest headache: How to finish the season strong
New South Florida head coach Willie Taggart is taking over a program that has struggled down the stretch in recent years.
He will be making his best attempt to change that, and the schedule at the end of the season is very favorable to do so.
The Bulls will take on Memphis and SMU at home in November, but they end the season at Central Florida and Rutgers.
Biggest headache: How to replace Matt Barkley
Matt Barkley may have had his struggles last season, but the quarterback will be sorely missed in 2013.
The front-runner to replace him is sophomore Max Wittek, but he may get some competition from 5-star recruit Max Browne.
Browne was one of the most talented quarterbacks in the class and if he is ready to go, he will almost certainly be the starter at the beginning of the season.
Kiffin will have a big decision with the beginning of spring practice.
Biggest headache: Dealing with a new conference
June Jones and his SMU Mustangs managed to win seven games last season, including a bowl domination of Fresno State.
They went 5-3 in Conference USA, winning five of their final seven games of the season.
The schedule is going to be a little tougher in 2013 with the team moving to the Big East. Look for Jones and his bunch to have their fair share of struggles this coming season in a new conference.
Biggest headache: How to turn around the program
Todd Monken is taking his first head coaching job with Southern Miss, inheriting the only team who failed to win a game in 2012. Monken takes over after serving as the offensive coordinator at Oklahoma State the past two years.
The Golden Eagles were 0-12 a year ago, so they can go nowhere but up.
He is an offensive mind, but Southern Miss struggled on both sides of the ball and will need help on both offense and defense.
Biggest headache: Replacing Stepfan Taylor
Stanford head coach David Shaw has done an excellent job in his first two seasons at Stanford, but things are going to be a little tougher this year with running back Stepfan Taylor having graduated.
Taylor carried the load the past three years for Stanford, rushing for over 1,100 yards each season.
There are some viable candidates to replace him, including Anthony Wilkerson, Remound Wright, Ricky Seale and Barry Sanders Jr.
Not a bad group to choose from.
Biggest headache: Life without Ryan Nassib
Syracuse was a bit of a surprise last season, coming on strong at the end of the year to win a share of the Big East crown.
Now the Orange have a new conference and a new head coach, but perhaps the largest challenge for Scott Shafer as spring practice begins is replacing star quarterback Ryan Nassib.
Nassib was a major reason why the Orange won eight games a year ago. Considering all of the changes this year in Syracuse, it won't be very easy to match.
Biggest headache: How to replace star running backs
New Temple head coach Matt Rhule is taking over a program that former head coach Steve Addazio left in good shape.
There are questions to be answered at running back, as both Matt Brown and Montel Harris have moved on.
Brown and Harris carried the bulk of the load last season for the Owls, so Rhule will have to come up with a new game plan.
Biggest Headache: Finding wide receivers
Tennessee not only loses quarterback Tyler Bray early to the NFL draft, but the Vols are also going to have to replace a trio of wide receivers that caught a lot of passes last season.
Justin Hunter and Cordarrelle Patterson have declared for the NFL draft and No. 3 wide receiver Zach Rogers has also graduated. Throw in the graduation of tight end Mychal Rivera and new head coach Butch Jones will have his hands full finding new wide receivers.
Finding the right players to fill the skill positions will be very important if Tennessee is to have a successful season.
Biggest headache: How to get more production from the quarterback position
Last season there was a quarterback battle between David Ash and Case McCoy; this year it appears that Ash is firmly entrenched as the starter heading into the season.
It is not out of the question for Ash to stumble and McCoy to take over, but whoever eventually wins the starting job before the season begins will have to play much better in 2013.
Head coach Mack Brown has probably lost enough sleep over the past few months thinking about his quarterback situation.
Biggest headache: How to get better in the SEC
There is no question that Texas A&M was one of the biggest surprises in the country last season as first-year head coach Kevin Sumlin led the team to an 11-2 record and a top-five ranking by the end of the year.
In 2013, there will be a lot of SEC teams looking to enact a little revenge on the Aggies, and at the top of that list is Alabama.
The Crimson Tide have definitely circled that game on the schedule. Sumlin and his group also have a road trip to Baton Rouge at the end of the season.
The national championship is not out of the question for this group, but improving in the SEC will be the first step toward that.
Biggest headache: Can Casey Pachall return to form?
TCU struggled through a season of injuries and suspensions in 2012, and the 2013 season is almost certain to be better based on the young talent returning.
A lot of the success in 2013 for the Horned Frogs will hinge on the return of quarterback Casey Pachall.
Pachall missed the final nine games of the 2013 season as he battled a drug addiction. If he can come back healthy, this could be a very dangerous team in 2013.
Biggest headache: How to compete in a talented Sun Belt conference
Texas State played its first season at the FBS level last year as a member of the now-defunct WAC.
It was not all bad in the conference, as the Bobcats finished the year 4-8 overall and 2-4 in the league.
As head coach Dennis Franchoine and his squad enter the Sun Belt, the conference is going to be a little stiffer and the four wins from a season ago will not be easy to come by.
Biggest headache: How to succeed as a first-year head coach
Kliff Kingsbury is taking over a big-time program for his first season as a head coach, and that is no easy task.
Running a Big 12 program is a very tall order, particularly for a guy who's never been a head coach and only has five years of assistant coaching experience.
Throw in the fact that he is only 33 years old and the biggest challenge for Kingsbury will be finding a way to win during his first season in the Big 12.
Biggest headache: How to transition back to the college game
UTEP head coach Sean Kugler served as the Pittsburgh Steelers' O-line coach the past few seasons.
He will now need to transition back into the college game after spending 11 of the past 12 seasons in the NFL with the Detroit Lions, Buffalo Bills and Steelers.
Kugler will be taking over a UTEP program that only won three games a season ago and struggled to score points all season long.
Biggest headache: How to succeed in Conference USA
UT-San Antonio head coach Larry Coker is certainly a very familiar name from his days at Miami.
Last season he led the Roadrunners to eight wins in their first season as an FBS program. Most of those wins didn't come against FBS schools, but the Roadrunners are moving to Conference USA for the 2013 season.
That is a huge jump for a team that wasn't even at the FBS level two years ago. It will be interesting to see how the team fairs with their challenging schedule in 2013.
Biggest headache: Finishing the season strong
Toledo is another MAC school that started off the season very strong. The Rockets began the year 8-1 but lost three of their final four games of the season to finish the year 9-4.
Second-year head coach Matt Campbell will be looking to improve from last year.
There is certainly going to be some pressure on Toledo this coming season as the Rockets will be one of the favorites in the MAC once again.
Biggest headache: How to rebound from two consecutive down years
Troy Trojans head coach Larry Blakeney will be entering his 25th season running the program and has led the team from Division II to I-AA all the way to the FBS level.
Over those 24 years, the Trojans have posted a 168-99-1 record despite two consecutive losing seasons.
After winning the Sun Belt five years in a row, Blakeney will need to find a way to keep his Trojans on track in 2013.
Biggest headache: Improving on defense
Tulane struggled on both sides of the ball in 2012, but the defense was the main reason why the team finished the year 2-10 in 2012.
The Green Wave was No. 118 in the country, allowing 38.4 points per game.
Head coach Curtis Johnson will be entering his second season with the program and has a big challenge ahead trying to turn things around.
Biggest headache: Navigating a challenging non-conference schedule
Tulsa is certainly going to be one of the favorites to win Conference USA after Central Florida left for the Big East.
However, the Golden Hurricanes are playing a very challenging non-conference slate beginning with a road trip to Bowling Green.
There is also a road trip to Oklahoma and a home game against Iowa State.
Head coach Bill Blankenship and his team should be well-prepared for Conference USA after the challenging out-of-conference portion of their schedule.
Biggest headache: Replacing Johnathan Franklin
UCLA had an excellent 2012 season under first-year head coach Jim Mora Jr.
A lot of that success was because the Bruins rode the back of star running back Johnathan Franklin. He carried the ball 282 times for 1,734 yards and 13 touchdowns.
Losing him will be a big dent in the UCLA running game and Jim Mora Jr. has until August to find a replacement for him.
Biggest headache: How to rebound from 2012
Utah suffered through a season of injuries in 2012 on their way to being one of the biggest disappointments in the Pac-12.
The Utes only won five games and missed out on a bowl game for the first time in head coach Kyle Whittingham's tenure.
He will be looking to move forward from their poor showing in 2012 and spring practice is a chance for that to happen.
Biggest headache: How to continue the program's success
First-year Utah State head coach Matt Wells is taking over a program with which he is very familiar; Wells has spent the past four seasons as the offensive coordinator of the Aggies.
He is replacing Gary Anderson, who took over the Wisconsin job. Anderson led the Aggies to an 11-2 campaign in 2012 and there are definitely some big shoes to fill.
Wells will be asked to continue the success of the program, which won't be easy as the Aggies join a very competitive Mountain West conference.
Biggest headache: Playing with a target on their back
Vanderbilt is transitioning from the hunter to the hunted in 2013. They will certainly not be one of the top teams in the SEC, but the Commodores are no longer on the bottom.
Head coach James Franklin has built quite a program in Nashville; Vanderbilt won its final seven games of the season to finish the year 9-4.
This year there will be plenty of teams gunning for Vanderbilt so head coach James Franklin better have his team ready for battle.
Biggest headache: Finding help at the quarterback position
Virginia struggled last season, finishing the year 4-8. Part of the reason for those struggles was the play of quarterback Michael Rocco.
Rocco struggled most of the year and has since transferred to Richmond to play for his uncle Danny.
Junior Phillip Sims saw a lot of snaps last season and will be counted on as the starter in 2013. He will need to improve if Virginia is going to get back to a bowl game this coming season.
Biggest headache: Recovering from the debacle of a season that was 2012
Not seeing a Virginia Tech team win at least 10 games comes as a huge surprise to most. The Hokies have had so much success under head coach Frank Beamer that a 7-6 mark in 2012 seemed like an awful season.
Do not expect that to be the case once again in 2013.
Frank Beamer is not used to losing and neither are the Hokie fans. He has certainly been chomping at the bit to get back at it in 2013.
Biggest headache: Offense
Wake Forest was another ACC team that was a slight disappointment in 2012, finishing the year 5-7 and missing out on a bowl.
The struggles came on the offensive side of the ball as Wake Forest averaged only 18.5 points per game.
They had one of the worst offenses in the country, particularly down the stretch, only averaging 9.7 points per game over the final three contests.
Biggest headache: Offense
Washington struggled on offense last season even though the talent was there to succeed.
The Huskies were No. 90 in the country in points per game, averaging only 24. Part was due to a challenging schedule, but their poor performance largely stemmed from the struggles of quarterback Keith Price.
The Huskies will be looking to improve on a 7-6 campaign and to do that they'll need to get the offense together.
Biggest headache: The running game
Part of the reason Washington State finished with a 3-9 record in 2012 was the complete lack of a running game.
The Cougars were dead last in the country, only averaging 29.1 rushing yards per game. No player on the roster rushed for more than 280 yards.
That is going to have to improve dramatically to succeed in the Pac-12.
Biggest headache: Replacing playmakers on offense
West Virginia was very talented on the offensive side of the ball in 2012, but that might not exactly be the case in 2013, as the Mountaineers have to find some new playmakers on offense.
Quarterback Geno Smith was one of the best passers in the country in 2012, and his favorite target Tavon Austin is also moving on to the next level.
There is still some talent returning, but head coach Dana Holgorsen will definitely have his hands full trying to put together an offense like West Virginia had in 2012.
Biggest headache: Succeeding at a new program
The saga of Bobby Petrino has been well-documented and now he is getting another chance as he takes over Western Kentucky. Petrino will bring the level of coaching experience that the university has never had.
The Hilltoppers won seven games last season and look to improve under their new coach
Petrino will need to prove himself once again and show that he can be a leader.
Biggest Headache: Running a program for the first time
Not only has new Central Michigan head coach P.J. Fleck never been a head coach, he's never even been an offensive coordinator.
He spent last season as the wide receivers coach for the Tampa Bay Buccaneers and also spent two seasons in the NFL with the San Francisco 49ers.
It will be interesting to see how he does running a program for the first time. There is no doubt that it is going to be quite a challenge for Fleck.
Biggest headache: Continuing the Badgers' success
New head coach Gary Andersen is tasked with continuing Wisconsin's success as a major contender in the Big Ten.
Andersen is taking over for Bret Bielema. Bielema led the Badgers to three straight Rose Bowls and a 68-24 record during his seven seasons in Madison.
Talk about filling shoes, Andersen will have a chance to get started right away during spring practice.
Biggest headache: Improving on defense
Wyoming won four games last season after struggling defensively all year
The Cowboys allowed 33.4 points per game, good for No. 99 in the country.
If head coach Dave Christensen and his team plan on improving on last year's record, they'll need to find some better players on the defensive side of the ball in 2013.
