NFL Free Agents 2011: Power Ranking the Top 50 Undrafted Free Agents

News that the NFL lockout is over is being greeted with cheers, popped corks and lit cigars by fans. For players and the 32 NFL teams, this news means it's time to get to work.

That work will start as each NFL team begins contacting and negotiating with the 300-plus available undrafted free agents, starting today most likely.

Each NFL team will assemble a big board of their priority undrafted free agents, a list they have had since late April and we have too. The list will serve as a guide for the best players available and how we would attack undrafted free agents if this were our team.

50. Quarterback Scott Tolzein, Wisconsin

Positives: An accurate passer familiar with a pro-style run game. Scott Tolzien was a game manager at Wisconsin but could do damage with good intermediate and deep accuracy, particularly when throwing right.

Negatives: As mentioned above, Tolzien is not known for his arm strength or his field vision. He can struggle when pressured. Played behind a very strong offensive line and with the benefit of a productive run game. Should not be asked to win games on his own.

Best NFL fits: Green Bay Packers, Indianapolis Colts, Seattle Seahawks

49. Defensive End Wayne Daniels, TCU

Positives:  An underrated pass rusher, Wayne Daniels has the skills to transition from the 4-3 defense at TCU to an NFL 3-4 scheme well. He is active and athletic, with the speed to chase players.

He has limited experience standing up in a two-point stance, but has shown the agility and flexibility to drop his hips and sink into coverage.

Negatives: Daniels may struggle at dipping his shoulders to elude the pass rush. A former defensive end, learning to work down the line and set the edge at the point of attack against the run could be an issue. There is also the trouble of learning how to drop back into coverage.

Best NFL Fits: New York Jets, New England Patriots, Green Bay Packers, Houston Texans

48. Center Kris O'Dowd, USC

Positives: Having played in a pro-style system under Pete Carroll and Lane Kiffin, Kris O'Dowd is well versed in the intricacies of the NFL game. He is a productive pass blocker with quick feet and hands.

He has experience in both shotgun and under-center snaps.

Negatives: Is a bit undersized for the NFL. May need to move to guard, as he is not strong enough to handle nose tackles at the point of attack alone. Shorter than average arms and small hands may limit him in pass blocking.

Best NFL Fits: Seattle Seahawks, Denver Broncos

47. Guard Justin Boren, Ohio State

Positives: Justin Boren comes from a power conference where he saw upper-level college talent on a weekly basis. He's an accomplished and productive run blocker.

Has played both guard and center at Ohio State. Has shown he can be very explosive firing off the ball.

Negatives: Boren was known for coming off his blocks too early and failing to finish on plays. He was also hurt by a lack of agility and flexibility, particularly in his hips, that kept him from looking like an adequate blocker in moving or pulling situations.

Best NFL Fits: New England Patriots, Pittsburgh Steelers, Oakland Raiders

46. Wide Receiver Jeff Maehl, Oregon

Positives: A highly productive college receiver, Jeff Maehl's statistics speak for themselves. He has experience both in a flanker and slot position. Can be used in motion or on the line of scrimmage.

While he lacks elite speed, his route running is dependable and consistent. Has good overall height and length.

Negatives: The only real knock on Maehl was his speed. His registered time of 4.65 was considered the deal breaker for Maehl's shot of being drafted. Maehl can beat the odds and become a productive possession receiver.

Best NFL Fits: San Francisco 49ers, Arizona Cardinals, Kansas City Chiefs, Seattle Seahawks

45. Fullback Henry Hynoski, Pitt

Positives: Henry Hynoski ranks as one of the most physical players available in the 2011 NFL draft class. He is a triple-threat as a receiver, runner and blocker.

Hynoski compares well to Cleveland Brown fullback Lawrence Vickers, as a player who can be on the field on all three downs in multiple roles.

Negatives: A hamstring injury at the NFL Combine but a damper on Hynoski's pre-draft prep work. For being a very physical player he is not a great blocker in terms of angles and fundamentals.

He will need time to develop as a blocker. During that time he must work on running with a lower pad level.

Best NFL Fits: Cleveland Browns, New Orleans Saints, Houston Texans

44. Quarterback Adam Weber, Minnesota

Positives: Adam Weber does a lot of small things well. He has good mechanics, excellent field vision and manages the game well. He throws a beautiful deep ball and makes an effort on and off the field that can be built around.

There is a lot of potential here.

Negatives: Weber is undersized, a little slow and has just an average arm. When viewing him in shorts, or even in practice, it's hard to see what makes him tick.

He fails the eyeball test immediately. Could stand to throw with more zip on the ball, as his passes tend to take too long to reach their target.

Best NFL Fits: Indianapolis Colts, Arizona Cardinals, Miami Dolphins

43. Running Back Noel Devine, West Virginia

Positives: A dangerous and exciting runner, receiver and return man, Noel Devine can break a game open with one touch of the ball. He has experience as a multi-threat style player and could fit well in a wildcat package or as a return man/receiver ala Dexter McCluster.

Negatives: The big (no pun intended) issue here is that Devine is tiny. At 5'8" and 180 lbs, many worry that Devine was just too small to hold up in the NFL.

Injuries at West Virginia and may red flags due to "character concerns" also hurt.

Best NFL Fits: Miami Dolphins, Minnesota Vikings, Denver Broncos

42. Quarterback Pat Devlin, Delaware

Positives: Coming from the same offense as Joe Flacco, Pat Devlin is ready for an NFL system. He has a big arm and a fluid throwing motion to deliver the ball on short, intermediate and long range throws.

With the right amount of time and mentoring, Devlin could develop into a nice backup quarterback.

Negatives: Devlin is not Joe Flacco, let's get that out of the way first. He's smaller, slower and has less of a rocket. Devlin also beat up against weak competition at Delaware and then failed to hold his own in postseason All-Star games.

Best NFL Fits: Philadelphia Eagles, Green Bay Packers, Washington Redskins

41. Tight End Joe Torchia, Virginia

Positives: The Virginia offense has lacked playmakers in recent years. One player worth watching was Joe Torchia. A big, physical tight end, Torchia was a bit of a throwback to the Brent Jones and Jay Novacek days.

He has the frame to be a good blocker once his technique improves. As with most Virginia players, he's exceptionally well coached and disciplined.

Negatives: Torchia missed the second half of the 2010 season with a shoulder injury that severely limited his ability to prepare for the 2011 draft. Before his injury there were questions about his speed and agility, two things that an NFL tight end these days must be able to do.

Best NFL Fits: New England Patriots, Atlanta Falcons, Kansas City Chiefs

40. Linebacker Mario Addison, Troy

Positives: Mario Addison has ideal size for today's outside linebacker at 6'3" and 245 lbs. He is athletic with great muscle tone and overall agility. In 2010, Addison posted 10.5 sacks, a great number no matter the level of competition.

Addison's skills project well as either a weakside linebacker in a 3-4 defense or a 4-3 scheme.

Negatives: Playing at Troy doesn't put you on the national radar much. Addison was not invited to the Combine or Senior Bowl and struggled to get noticed. There is also concern that in moving from defensive end to outside linebacker he would struggle in coverage.

Best NFL fits: Arizona Cardinals, San Francisco 49ers, Green Bay Packers, New England Patriots

39. Center Alex Linnenkohl, Oregon State

Positives: A tough as nails type player, Alex Linnenkohl is the definition of a gritty offensive lineman. He fights with defenders, earning him a reputation as a work-ethic player who never gives up. As a center he has an excellent center of gravity and really does a good job getting arm extension after the snap.

In terms of character he's the total package. This is the guy you want your daughter to bring home.

Negatives: The only negative on my old notes about Linnenkohl was his lack of athletic ability. If a team is running a zone scheme they may have eliminated him from their boards altogether. He'll struggle getting lateral or vertical even in chasing to the next level.

Best NFL fits: Pittsburgh Steelers, Miami Dolphins, Oakland Raiders, Carolina Panthers, Arizona Cardinals

38. Guard Ricky Henry, Nebraska

Positives: A big, mauler of a guard, Ricky Henry was a productive member of the Cornhusker offensive line. His ability as a run blocker was developed well while at Nebraska. He's a stationary player who is at his best waiting for pass rushers or going one-on-one in a closet with tackles.

Negatives: Henry is not a mobile guard. He will struggle to pull or release to the second level. He did better as a senior on trap plays, but his overall game is hurt by his inability to get outside the tackle box to block.

Best NFL fits: Philadelphia Eagles, Oakland Raiders, San Diego Chargers, Dallas Cowboys

37. Wide Receiver Terrence Turner, Indiana

Positives: Terrance Turner passes the eye ball test. At 6'2" he packs 220 lbs on his frame, and he uses that well in boxing out defenders and working to get open against pressure coverage.

Turner improved dramatically in his senior season, showing the potential to continue developing into a quality wide receiver.

Negatives: Turner was never a marquee player at Indiana. Blame some of that on the quarterback, but his talent was better than his production. He will need time to learn the position once in the NFL and could benefit from a solid position coach.

Best NFL fits: Cleveland Browns, Jacksonville Jaguars, Carolina Panthers, St. Louis Rams

35. Cornerback Mike Holmes, Syracuse

Positives: An active cornerback with good size, Mike Holmes looks like an NFL starter at either cornerback, free safety or kick returner. He has the speed and skills to become a dual-threat player in the secondary and on special teams, especially as an early contributor.

Negatives: Holmes was coming off shoulder surgery and was seriously limited in what he could do during the pre-draft phase. You also worry about his 40 times, which were all over the place. He ran anywhere from 4.45 up to a 4.64.

Best NFL fits: Jacksonville Jaguars, Houston Texans, Tampa Bay Buccaneers

36. Wide Receiver Tori Gurley, South Carolina

Positives: At most schools, a guy that is 6'4" and 230 lbs would dominate. Tori Gurley has the size/speed combination to do that, but he never put it all together on the field.

Gurley has amazing hands. He dropped zero passes in 2010 and is almost unstoppable in the open field due to his size and strength.

Negatives: Gurley failed to dominate at South Carolina. He does have great size, but his production levels were too low. He may also lack the deep speed to play the position. A move to tight end would not be unlikely.

Best NFL fits: New England Patriots, Chicago Bears, St. Louis Rams

34. Running Back Graig Cooper, Miami

Positives: A talented athlete and all-around football player, Graig Cooper has the look of many former Miami running backs. Cooper has the size you love and looked to be recovered from a 2009 ACL injury late in the 2010 season.

Cooper was the fastest back at the Combine in three-cone drills (6.66 seconds).

Negatives: The 2009 ACL tear is a big red flag, but given time he should be fine there. Many were also worried about the "bird legs" Cooper sports (see above) and lack of definition in his lower body.

He will definitely benefit from a full season of NFL workouts.

Best NFL fits: Denver Broncos, Green Bay Packers, Chicago Bears

33. Punter Ryan Donahue, Iowa

Positives: A very productive punter from a school known for producing top special teams talent, Ryan Donahue is an NFL ready punter.

Negatives: The sole reason he wasn't drafted is because of his position and the lack of value applied to it. Donahue will be ready to fight for a starting job in the NFL this spring.

The only negative we found when scouting him was his delivery (two-and-a-half steps) and his time from snap to toe. If he can speed up, he'll be set.

Best NFL fits: All

32. Tight End Charlie Gantt, Michigan State

Positives: Charlie Gantt has ideal size for an NFL tight end. He is big enough to box out defenders and strong enough to fight off press coverage at the line of scrimmage.

Was a productive receiver and reliable target in both redzone and standard packages.

Negatives: Gantt's biggest flaw is his lack of speed. With a timed 40-yard dash of just 4.86, Gantt would struggle to run away from linebackers and safeties in coverage.

If he can find a system that lets him sit in zones and not try to turn away from man coverage, he'll be able to adjust well.

Best NFL fits: Philadelphia Eagles, Dallas Cowboys, Minnesota Vikings, New York Giants

31. Guard Garrett Chisolm, South Carolina

Positives: A former walk-on who would work his way into a starting role, Garrett Chisolm is a hard worker first and foremost. Is a very impressive, fluid athlete. Might even be able to play tackle in a zone system due to his ability to move in space.

Is a guy you stick on the practice squad and then prepare him to start.

Negatives: Chisolm can have issues with getting enough bend in his long legs to properly execute and finish a block. Can really get run over by a strong bull rush. He needs to learn to use his hands better and to use them faster. Needs a lot of attention before he's field ready.

Best NFL fits: Washington Redskins, Green Bay Packers, Houston Texans, Atlanta Falcons

30. Tight End Zack Pianalto, North Carolina

Positives: A high-character player, Zack Pianalto was one of the few Tar Heel starters not suspended or investigated during the 2010 season. He is a tough player, willing and able to play through injury. His production was solid enough to not be an issue.

Negatives: Pianalto was banged up a lot during this college career. He's also a below average athlete who will struggle to gain separation from NFL defenders.

Best NFL fits: St. Louis Rams, Washington Redskins, San Diego Chargers

29. Defensive Tackle Martin Parker, Richmond

Positives: A durable player who dominated as the small school level, Martin Parker is considered a very good prospect as a 3-technique tackle in a 4-3 scheme.

He has very good initial burst and is able to disrupt the offensive line. Can beat blockers at the point of attack and get penetration.

Negatives: Coming from a small school, he has not seen upper-level competition. Is a decent athlete but nothing exceptional in terms of measurements or on-field ability. He will take plays off and needs a fire lit under him to play hard every down.

Best NFL fits: Philadelphia Eagles, Tampa Bay Buccaneers, St. Louis Rams, Detroit Lions, Seattle Seahawks, Denver Broncos, Carolina Panthers

28. Defensive End Ryan Winterswyk, Boise State

Positives: A high-motor athlete with good quickness off the ball, Ryan Winterswyk is one of the better known "name" players available in the UDFA class.  Has ideal size for the position and was very production at Boise State. A former walk-on.

Negatives: As a player he is a good but not great defensive end who will get washed down by a good offensive tackle. Has been beaten up throughout his career and struggles to stay healthy. Lacks elite pass-rush and run stop skills. Gets by on athleticism.

Best NFL fits: Cleveland Browns, Atlanta Falcons, Carolina Panthers

27. Kicker Kai Forbath, UCLA

Positives: One of the most productive kickers in college football, Kai Forbath was excellent during his four-year run as kicker for UCLA. Has a career long of 54 yards. Is as NFL ready as any kicker to come out of college in the last decade.

Negatives: None

Best NFL fits: All

26. Safety David Sims, Iowa State

Positives: A highly productive former JUCO player, David Sims quickly established himself at Iowa State. Averaged 92 tackles per season at ISU. Is a smart, savvy centerfielder who is capable of running the defense.

Does a great job locating the ball. Very disciplined against play action and misdirection. Pretty fluid athlete.

Negatives: Sims lacks the height and speed we like to see in safeties. He was suspended for 2010 season opener and removed as a captain after accused of charging food, gas and shoes to a debit card that was not his. A JUCO player, he failed to become eligible at Oklahoma. Will turn 25 this October.

Best NFL fits: Dallas Cowboys, San Diego Chargers, Indianapolis Colts, Jacksonville Jaguars, Houston Texans

25. Wide Receiver Armon Binns, Cincinnati

Positives: Armon Binns really has a great makeup. He has above average height and the required speed and bulk for the position. He's a tough, durable player who gives a ton of effort.

Is good at tracking the ball over both shoulders. Has big, strong hands. Was productive in his final two seasons at Cincy. Could be a nice vertical threat.

Negatives: Can be limited in his routes. Has not shown the natural ability to drop hips and chop his feet into direction changes. Is a little weak and can be knocked off his route or his release if pressed hard enough.

Will need to begin his NFL career as a motion receiver or in the slot, where he can get a cleaner release.

Best NFL fits: Green Bay Packers, Arizona Cardinals, New York Jets, Philadelphia Eagles

24. Safety Will Hill, Florida

Positives: Will Hill has ideal size and speed for the safety position. He's a hard hitter and is not afraid to put himself on the line for the big play. Has been a key special teams player and can contribute as a return man and tackler. Is best in zone coverage and fits a Cover 2 scheme well.

Negatives: You really do not know which Will Hill you are getting. If you look at the athlete you would think he was a draftable player, but then you dig deeper and see tweets about marijuana use and sex.

He was involved in community service, but how much of that was voluntary? When a player has red flags like this and doesn't get drafted, it's usually for a good reason.

Best NFL fits: Tampa Bay Buccaneers, Detroit Lions, Cincinnati Bengals

23. Tight End Weslye Saunders, South Carolina

Positives: Weslye Saunders was rated by many as a top-100 pick before the 2010 season. He has amazing size at 6'5" and 270 lbs, and he matches that with good speed.

Saunders is a physical freak and a matchup nightmare. He'll use his size to box out smaller defensive backs, and most linebackers. Could become a valuable red-zone threat.

Negatives: Saunders missed time in his career due to injury and also to suspension, more than once. Contract with an agent before his senior season led to his missing the entire 2010 season.

Saunders must also answer questions about a perceived poor work ethic and a left foot fracture before an NFL team will trust him.

Best NFL fits: San Diego Chargers, Seattle Seahawks, New York Giants, Detroit Lions

22. Cornerback Ryan Jones, NW Missouri State

Positives: Not much can be found about Ryan Jones other than the limited film work we were able to acquire from NW Missouri State, a Division II school. Jones dominated against lesser competition, but his individual skills would indicate he has NFL ability.

He's a dangerous cornerback and also a heady special teams player. He could make his impact felt as a gunner on punt coverage and kickoffs early on.

Negatives: Jones would benefit from being coached at a higher level. His instincts are still raw, and he's survived on athleticism alone for the last four years. As he develops, Jones could become a solid second-tier cornerback.

Best NFL fits: San Diego Chargers, Dallas Cowboys, Jacksonville Jaguars, Detroit Lions

21. Wide Receiver Terrence Toliver, LSU

Positives: Terrence Toliver comes from an NFL factory at LSU, where he was a productive starting receiver in an offense that lacked an elite quarterback. He has an ideal frame for a No. 1 wide receiver and enough speed to make it as a vertical threat.

Negatives: A March arrest in 2011 definitely hurt Toliver's draft stock. He'll struggle to handle intermediate and short routes in a timing based offense, as he's a long-strider without the quick twitch you look for in slot receivers.

Best NFL fits: Cleveland Browns, St. Louis Rams, San Diego Chargers, New York Giants

20b. Tackle Willie Smith, East Carolina

Positives: Ideal height and build for a swing tackle in a zone scheme. Willie Smith comes to the NFL with average measurables and average production, but there is a lot to like about his raw potential.

He's a good athlete with a basic idea of how to succeed at left tackle. You also cannot coach his athleticism, something every team would love at left tackle.

Negatives: He's raw. He will need to spend one or two years learning the offensive side of the ball. He's only been at tackle for three seasons, so this is all new to him.

Best NFL fits: Houston Texans, Buffalo Bills, Kansas City Chiefs, Atlanta Falcons

20a. Quarterback Adam Froman, Louisville

Positives: A smart quarterback who quickly acclimated to the NCAA level after transferring from Santa Rosa Junior College. Adam Froman is a productive passer with NFL measurables and arm strength.

Is an underrated athlete who can make plays outside the pocket, even picking up yards on designed runs. Does a nice job leading his receivers. Is a quick learner with a lot of room to grow.

Negatives: Relatively inexperienced. Will need to sit and learn for two to three seasons, preferably behind a veteran. Has a long delivery on the ball, something that can get him in trouble behind a bad offensive line.

Best NFL fits: Indianapolis Colts, San Diego Chargers, Green Bay Packers

19. Wide Receiver Dane Sanzenbacher, Ohio State

Positives: Dane Sanzenbacher was a fun wide receiver to watch in college. He should have his chance in the NFL, too. His character and work ethic are off the charts. He was a three-time Big Ten All-Academic player.

He's also not afraid to go across the middle. He runs nice, sharp routes and shows ball skills that most wouldn't see on a smaller receiver. He'll remind you of Wes Welker if you watch too long.

Negatives: Sanzenbacher lacks the speed to take a short pass and turn it into a huge play. He's a bit undersized and could use 10 more pounds of muscle on his frame.

He's not incredibly fast out of his cuts, something that will prevent him from getting on the field, no matter how hard he works.

Best NFL fits: San Diego Chargers, New England Patriots, Cleveland Browns

18. Linebacker Orie Lemon, Oklahoma State

Positives: Orie Lemon is a tough kid with a feel-good story about overcoming adversity. You find yourself wanting him to do well. He's a high motor player with great productivity. Is thick and strong, especially through the lower body.

Is an ideal TED linebacker in a 3-4 defense, where he will absorb blocks and fight for the ball. Can be very powerful at the point of attack. Is great at stepping up to fill a hole.

Negatives: Can be a little late to the hole if he misses his reads. He missed the entire 2009 season with a torn ACL and was only starting to get his speed back late in 2010. If healthy, he would have been higher on our list.

Best NFL fits: San Francisco 49ers, Green Bay Packers, Houston Texans, Buffalo Bills

17. Linebacker Scott Lutrus, Connecticut

Positives: Scott Lutrus just looks like an NFL linebacker. He has ideal height, bulk and speed to play outside linebacker in the NFL for a long time. He was twice a team captain at UConn and a Big East All Academic member once.

He does a nice job reading his keys and staying in position to take away cutbacks. Is disciplined in his pursuit angles and drop steps.

Negatives: Two things worried me about Lutrus before the draft. 1) He has missed eight games in his career due to stingers. 2) He was arrested in 2009.

Both red flags, and while the arrest is more serious, it was likely the history of stingers that kept Lutrus out of the draft.

Best NFL fits: Chicago Bears, Denver Broncos, Carolina Panthers, Seattle Seahawks, Detroit Lions

16. Defensive Tackle Brandon Bair, Oregon

Positives: Brandon Bair was a productive member of a defense that tore through the Pac 10 last year. He has shown that he can get off the ball and make plays in the backfield (16 TFL in 2010). 

He's also a mature, steady player who you won't have to worry about off the field. That goes a long way in separating players who might be equal or close in talent.

Negatives: Bair is slightly underweight for a defensive tackle and perhaps a little too tall. He should make the transition to 3-4 defensive end once in the NFL.

He is not an overwhelming athlete, and he has relied too much on his strength and burst at Oregon. He'll need to learn counter moves and add weight in the NFL.

Best NFL fits: San Diego Chargers, San Francisco 49ers, Houston Texans, Green Bay Packers

15. Linebacker Mark Herzlich, Boston College

Positives: A productive starter at Boston College, Mark Herzlich is a story that pulls at the heart. He's a team leader with excellent work ethic on and off the the field. NFL teams would love to have a player of Herzlich's character.

When healthy, he has ideal size for the outside linebacker position. Pre-injuries he was an amazing athlete with great strength.

Negatives: You cannot argue with Mark Herzlich's production, but his career was changed with an Ewing's Sarcoma diagnosis in May 2009. He is cancer free as of October 2010, but this is a huge concern for any NFL team.

Best NFL fits: Baltimore Ravens (ILB), New York Giants, Philadelphia Eagles, San Diego Chargers (ILB)

14. Nose Tackle Ian Williams, Notre Dame

Positives: A squat, powerful defensive tackle, Ian Williams is ideal for a nose tackle position in a three or four-man front. Named Notre Dame's Lineman of the Year in 2010.

Was a captain in his senior season. Looked very good in Senior Bowl practices while recovering from injured MCL during the season.

Negatives: Teams were worried about the MCL, but that's a non-issue by now. Williams was at a position of little value for NFL teams, most who thought they would pick him up post-draft. He is not a pass-rusher, so don't expect him to jump in and get penetration. That's not his game.

Best NFL fits: San Francisco 49ers, Denver Broncos, Carolina Panthers, Houston Texans

13. Wide Receiver Ricardo Lockette, Fort Valley State

Positives: A rare NFL Combine invite to go undrafted, Ricardo Lockette was ideal measurables when looking at him as a raw athlete. Has above-average size and speed.

His long arms will be great as he becomes a vertical threat at the next level. No injuries, a clean slate.

Negatives: His production at the small school level was less than ideal, which points to how raw he is. Lockette bounced around small schools and JUCOs as he couldn't get eligible for D1 schools.

Will he be able to learn an NFL playbook? That's a big issue right now. Incredibly raw.

Best NFL fits: St. Louis Rams, Chicago Bears, Dallas Cowboys, Green Bay Packers, Tennessee Titans

12. Guard Zach Hurd, Connecticut

Positives: Zach Hurd has a great size/strength ratio for a starting guard in the NFL. A three-year starter at guard, Hurd is an accomplished run blocker with a massive frame and exceptional strength.

Was a team captain in 2010. Has upper-level strength. Uses his size well. Plays with a fiery emotion. A solid pass and run blocker. Could contribute.

Negatives: Had no red flags on our radar pre-draft. Is a mauler and not an athlete, which limits him in terms of NFL use. He does struggle for position at times, but these are all minor gripes.

I'm still not sure why he wasn't drafted.

Best NFL fits: All

11b. Defensive End Pierre Allen, Nebraska

Positives: One of the biggset surprises of the undrafted class, Pierre Allen has the ideal skill set for an NFL defensive end. He has the size (6'4", 273 lbs) and speed to line up as a right or left defensive end in a 4-3 set up

. Allen was productive at Nebraska who most thought would be a top-125 pick.

Negatives: There aren't many if you look at Allen as a left end. He has, at times, ran too tall and made himself blockable by firing off too high.

He's battled a number of small injuries throughout his career that may have hurt his stock.

Best NFL fits: St. Louis Rams, Atlanta Falcons, Cleveland Browns

11a. Linebacker Nick Bellore, Central Michigan

Positives: Nick Bellore left Central Michigan as a decorated linebacker who started 51 straight games. A three-year captain, Bellore is a high character player who plays with the kind of toughness not seen often these days.

Is a read-and-react linebacker who uses his backfield keys to diagnose. Shows good discipline. Tough, strong player. Great pursuit. Plays with the right amount of reckless abandon.

Negatives: Is just an average athlete with decent height and bulk. He's weak in coverage and may be used only as a two-down linebacker in the NFL. Can be too slow getting and out of his breaks. Just not a good athlete.

Best NFL fits: Tennessee Titans, Tampa Bay Buccaneers, Buffalo Bills

10. Running Back Derrick Locke, Kentucky

Positives: Derrick Locke should have been drafted. Now he will have his pick of many potential NFL teams. He was a very productive player at Kentucky as a runner, receiver and returner. Is a true threat with the ball.

Is a hard worker, driven by his perceived lack of size to excel. Will give it all on the field. Has the talent and raw ability to make it in the NFL. A former track star, Locke is a burner with the ball in his hands.

Negatives: Is smaller than you'd like at 5'8" and 190 lbs. Has suffered some minor injuries in each of his college seasons. Lacks the power to run through tackles and would be a liability as a blocker or goal-line back.

Best NFL fits: Miami Dolphins, Cincinnati Bengals, New York Giants, Chicago Bears

9. Safety DeAndre McDaniel, Clemson

Positives: It would be hard to find a better safety than DeAndre McDaniel on the open market in the NFL right now. He's young, athletic, a punishing tackler and a productive player from a major conference.

His production, athleticism and tests were all good. Why he wasn't drafted remains a mystery.

Negatives: The baggage is all you worry about with McDaniel. He was an NFL level safety, but an arrest in 2008 is a major red flag on his record.

Best NFL fits: San Diego Chargers, Pittsburgh Steelers, New Orleans Saints

8. Defensive Tackle Cedric Thornton, Southern Arkansas

Positives: A very good penetrator, Cedric Thornton has the athleticism to be a force in a 3- or 5-technique, depending on the team that picks him up. He has the ideal build, speed and burst for the defensive tackle position.

The sky is the limit, it will just take patience as he develops from small school to NFL.

Negatives: Thornton dominated at a small school level and may struggle against NFL level blockers. He'll also be learning a new position, whether he lines up in a 4-3 or 3-4 in the NFL, as he got by on pure athleticism at Southern Arkansas.

Best NFL fits: Philadelphia Eagles, New England Patriots, San Diego Chargers

7. Running Back Mario Fannin, Auburn

Positives: An amazing athlete, Mario Fannin is a bit under the radar right now. He shouldn't be. Fannin may not have produced much at Auburn, but he was rarely given the chance.

His athleticism and ability to play multiple positions on offense will entice a number of NFL teams. He's a rare athlete.

Negatives: He has been known to put the ball on the floor. He'll have to work to get stronger and hold the ball correctly before an NFL coach will trust him full-time. Has been injured here and there but nothing major.

Best NFL fits: Cincinnati Bengals, Miami Dolphins, New York Jets, Oakland Raiders

6. Safety Joe Lefeged, Rutgers

Positives: It's a mystery why Joe Lefeged wasn't drafted. He's an ideal size, speed and agility for the position. He's been productive. He has the ball skills, quickness and tackling ability we all look for in a safety.

A team captain in 2010, Lefeged was one of the best defensive players at the Senior Bowl. We had him graded as a fourth-round pick at worst.

Negatives: The only possible explanation here is that Lefeged got timid after watching teammate Eric LeGrand leave the field paralyzed. This is a reason I've seen before, and it makes sense.

Lefeged, if he wants to play in the NFL, will have options. He has to get over the mental aspects though.

Best NFL fits: San Diego Chargers, Dallas Cowboys, Cincinnati Bengals, Cleveland Browns

5. Wide Receiver Darvin Adams, Auburn

Positives: Darvin Adams graded out before the draft as a late third-round pick on my personal big board, largely in part due to his amazing potential and seeing what he could do with a legitimate passer at quarterback.

Adams has great hands, a clean bill of health and the frame to get bigger and stronger in the NFL.

Negatives: To be very picky, he's a little slower than most teams would want for a vertical threat at 6'2". He could also benefit from adding 10 lbs of muscle. He lacks explosion, but this could come with better weight training.

Best NFL fits: All

4. Safety Jeron Johnson, Boise State

Positives: A personal favorite of mine, Jeron Johnson is like a little firecracker waiting to explode. He is a punishing tackler, a team leader and defensive quarterback. For being small, and a hard hitter, he hasn't missed a game since 2007.

Strong safeties like this are rare in an undrafted market. Many NFL teams will be lined up for Johnson's services.

Negatives: Undersized slightly at 5'10", Johnson can be beaten over the top. Can be too aggressive at times and must learn to be more disciplined against play action.

Due to his height he will struggle to high-point the ball. Will get caught up in traffic and can be blocked one-on-one.

Best NFL fits: Indianapolis Colts, Jacksonville Jaguars, Washington Redskins

3. Running Back Darren Evans, Virginia Tech

Positives: A downhill runner with amazing size and strength, Darren Evans should be a hot priority on the UDFA market. A mature player with a wife and a son, Evans will be a hard worker in an NFL camp. Is a physical runner with good burst and great vision for the cut back.

Is patient, especially for a young runner. Evans packs an amazing punch when carrying the ball. Teams must have been worried about a previous knee injury to have not drafted him.

Negatives: Coming off a season ending knee injury in 2009. In 2010 he was too often taking false steps to change direction. Must re-gain confidence in his knee to plant and go. Has not been a threat as a receiver.

Best NFL fits: Cincinnati Bengals, Miami Dolphins, Chicago Bears, Kansas City Chiefs, New York Giants

2. Safety Deunta Williams, North Carolina

Positives: Deunta Williams became a leader on the North Carolina defense during the 2010 season. He was a highly productive, very athletic free safety on a defense stocked with future NFL players.

Has good height/speed combination. Could stand to put on 10 lbs of muscle.

Negatives: Was unfairly red flagged by most teams after he was suspended for four games in 2010 due to violating NCAA rules regarding agent contact. Broken fibula in late 2010 forced him to miss most pre-draft activities, pushing him down the big board.

We are ranking him this high banking on a clean bill of health.

Best NFL fits: San Francisco 49ers, Houston Texans, Philadelphia Eagles, Denver Broncos

1. Cornerback Kendric Burney, North Carolina

Positives: Our No. 1 undrafted player available, Kendric Burney could step on to an NFL roster this week and make a play for a nickel job. He's productive, a hard tackler, a hard worker and a smart player.

His instincts and recognition graded among the top 10 cornerbacks in the 2011 class on our board. He's a playmaker, bringing in 11 career interceptions.

Negatives: The only knock is that Burney is just 5'8 3/8" tall. Other cornerbacks have made it in the NFL at this size, Burney just has to prove he's worthy of a roster spot.

As part of the North Carolina program in 2010, Burney (and many others) was suspended seven games while the NCAA investigated the program.
