NFL Free Agency 2013: Team-by-Team Primer

The 2013 NFL free agency period is finally here, and plenty of big names are hitting the open market. 

The following slides break down all the teams, in alphabetical order, as they head into free agency. The most glaring needs and a few likely targets are listed for each franchise. 

Each team's cap space is also provided.  

These numbers were calculated by taking Spotrac's "cap figure" for each team and subtracting it from the $123.9 million salary cap for 2013. 

The cap space isn't an official number, but it should be a close approximation to the money each team has to work with this offseason. 

Arizona Cardinals

Primary needs:

The Cardinals' top priority is to address the offensive line, which ranked among the worst units in the league in 2012. 

According to Pro Football Focus, only the Chargers and Colts posted a worse pass-block efficiency rating a season ago. 

Veteran Levi Brown will return from a triceps injury that cost him the entire 2012 season, but the other four spots on the line are up for grabs. At least one new starter should be found during free agency, with another possibly coming from the draft. 

On the defensive side of the ball, the Cardinals need to address the secondary. Entering free agency, only two safeties and two cornerbacks are under contract. 

Kerry Rhodes and Patrick Peterson hold down two of the starting jobs, but a strong safety and another starting cornerback must be found this offseason.

Potential targets:

The Cardinals don't have a ton of cap space, so they'll need to spend their money wisely. 

On the offensive line, veterans Jake Scott and Ramon Foster should be relatively cheap upgrades at either of the guard positions. 

Former Cowboy Gerald Sensabaugh could be a reasonably priced replacement for Adrian Wilson, who was recently cut, at strong safety. 

Salary cap space: $10.5 million

Atlanta Falcons

Primary needs:

The first order of business is re-signing Tony Gonzalez. Even at age 37, he remains one of the most efficient pass-catching tight ends in the league, and he was the target of 20 percent of Matt Ryan's pass attempts in 2012. 

Fortunately for the Falcons, Gonzalez is now leaning toward a return, according to Yahoo! Sports. 

The Falcons also need to address the defensive line, which has been depleted by the release of Ray Edwards during the season and John Abraham this past week.

In other cost-cutting moves, the Falcons also parted ways with veterans Michael Turner and Dunta Robinson.

As a result, the Falcons must find veteran replacements capable of filling those holes immediately. And they must do so on a relatively tight budget.

Potential targets:

Of their own free agents, cornerback Brent Grimes is the most likely to re-sign. He missed a significant portion of the season with an Achilles injury, so he may be available at a reduced rate. 

If they can't bring back Grimes, the Falcons may turn to another veteran such as Aaron Ross or Quentin Jammer.

To replace Turner, the Falcons may consider Rashard Mendenhall or Shonn Greene. Both are still young but won't break the bank due to inconsistent performances in recent years. 

Salary cap space: $12.5 million

Baltimore Ravens

Primary needs:

The once-mighty Ravens defense could take a significant step backward in 2012 if they're unable to sort out their issues at linebacker.

Ray Lewis has retired and Dannell Ellerbe is an unrestricted free agent. 

Re-signing Ellerbe should be a top priority, and adding another linebacker to pair with him would certainly help ease the loss of Lewis. 

Speaking of re-signing veterans, future Hall of Famer Ed Reed is also on the open market. 

The Ravens are unlikely to let Reed get away, but they should act quickly before a team such as the Patriots gets into the mix.

The Ravens could also use another weapon in the passing game, especially now that Anquan Boldin has been traded (via ESPN). As good as Joe Flacco looked during the playoffs, he won't be the same quarterback with Torrey Smith and Jacoby Jones as his only reliable receivers.

Potential targets:

If the Ravens think they can compete for another Super Bowl title in 2013, signing a veteran linebacker such as Brian Urlacher or Daryl Smith should be a high priority. Both Smith and Urlacher would offer significant upgrades in coverage, an area in which the Ravens struggled a season ago.

The Ravens may not be able to afford any of the top receivers on the market, but they could target a second-tier veteran such as Brandon Gibson or Michael Jenkins.

Salary cap space: $14.1 million

Buffalo Bills

Primary needs:

The Bills have built one of the strongest interior offensive lines in the game, but it could start to crumble if Andy Levitre is allowed to sign elsewhere. 

General manager Buddy Nix needs to make Levitre, who is just 26 years old, his top priority. 

The Bills could also use another weapon in the passing game. 

A slot receiver would be a nice addition to Stevie Johnson and T.J. Graham, who are both at their best on the outside. 

Linebacker is another area of concern, especially on the inside. A veteran presence at middle linebacker could help their defense take the next step.

Potential targets:

If the Bills are willing to pour some more money into the defense, either Daryl Smith or Dannell Ellerbe would be a nice additions at linebacker. 

They would each bring a veteran presence to a young unit in need of some leadership. 

The Bills will have a hard time enticing one of the big-name receivers to join a rebuilding process, but there are a few veteran slot receivers who could be options. 

Austin Collie, Julian Edelman and Early Doucet would all fit the mold of what the Bills are looking for on offense.

Salary cap space: $20.2 million

Carolina Panthers

Primary needs:

Charles Johnson and Greg Hardy are two of the best defensive ends in the game, but they have received no support from the interior defensive line in recent years. 

Adding a starting nose tackle and a pass-rushing three-technique tackle are priorities this offseason. 

The Panthers also created a glaring hole in the secondary by parting ways with veteran Chris Gamble. 

Josh Norman and Josh Thomas are now the top corners in Carolina, and defensive coordinator Sean McDermott can't feel comfortable about starting the season with that duo. 

Despite all the needs on defense, Cam Newton is still the future of this team, and the Panthers can't let another offseason go by without bringing in some support. 

Newton could use another weapon and some upgraded protection on the right side of the offensive line.

Potential targets:

The Panthers have to fill a number of holes and are operating on a tight budget, so don't expect any big names to land in Carolina. 

They're likely to address the defensive line early in the draft, but adding a veteran nose tackle such as Ma'ake Kemoeatu or Isaac Sopoaga would be wise move in free agency. 

In the secondary, veterans such as Mike Jenkins or Leodis McKelvin would add some much-needed depth at a relatively inexpensive price.

Salary cap space: $5.2 million

Chicago Bears

Primary needs:

The Bears' top priority this offseason is to re-sign veteran Brian Urlacher. 

While there's no question that Urlacher is nearing the end, he's still the heart and soul of the Bears defense and can't easily be replaced. 

Jay Cutler could also use some help on offense, in the form of improved protection and another weapon. 

The Bears will likely add a lineman early in the draft, but with so many holes on the offensive line, at least one starter should be brought in via free agency.

Potential targets:

If Urlacher is re-signed, the Bears won't have much money with which to work. 

To address the offensive line, they'll be limited to veterans such as Ryan Lilja or Doug Legursky.

If the Bears fail to re-sign Urlacher, they'll have to address the linebacker position. Daryl Smith would be an ideal replacement, but he may be too expensive. A more realistic option might be Bradie James.

Salary cap space: $5.2 million

Cincinnati Bengals

Primary needs: 

Re-signing Andre Smith is the top priority for the Bengals, but only if the price is right. Given his inconsistent career and history of weight issues, the Bengals would be wise to not overpay for his services. 

If Smith signs elsewhere, adding a quality right tackle is a priority. 

The Bengals could also use some upgrades in the secondary, especially at strong safety. Taylor Mays has failed to live up to expectations and primarily played a reserve role in 2012. 

The likely departures of Rey Maualuga and Manny Lawson also open up some holes at linebacker. 

Vontaze Burfict is expected to shift inside to fill Maualuga's spot, leaving gaps at strong-side and weak-side linebacker.

Potential targets:

With plenty of cap space, the Bengals can target just about anyone they want to bring aboard. 

If Andre Smith gets away, Eric Winston would be an excellent addition at right tackle. And he may ultimately be a cheaper and more consistent replacement for Smith.

This is a deep class for safeties, so the Bengals have some options there. Adrian Wilson and Louis Delmas are two possibilities.

At linebacker, Leroy Hill would be a great fit on the weak side. 

Salary cap space: $45.8 million

Cleveland Browns

Primary needs:

Jabaal Sheard will occupy one of the outside linebacker positions in defensive coordinator Ray Horton's new 3-4 scheme, but the other spot is up for grabs. 

The Browns could also use another playmaker in the secondary. Joe Haden is among the best in the game, but Sheldon Brown and Buster Skrine leave a lot to be desired on the other side. 

On the offensive side of the ball, an upgrade must be found at right guard.

Over the past two seasons, Shawn Lauvao ranks among the most unreliable starters in the league, committing 19 penalties and allowing nine sacks during his two years as a starter.

Potential targets:

The Browns have already been linked to Cliff Avril and Paul Kruger, according to NFL.com. Both Avril and Kruger would offer the Browns a significant upgrade at outside linebacker.

The Browns have also reportedly spoken with Antoine Cason, according the The Plain Dealer, who would be a solid option at cornerback next to Haden. 

With plenty of money to spend, the Browns could sign Avril or Kruger, and Cason, and still have room to address the offensive line. 

Andy Levitre would be an ideal fit at right guard. Slightly less expensive options would include Ryan Lilja and Leroy Harris.

Salary cap space: $49 million

Dallas Cowboys

Primary needs:

For the second straight year, the Cowboys need to address the offensive line, especially on the right side.

Mackenzy Bernadeau and Doug Free struggled in 2012, and both could be replaced this offseason. 

On the defensive side of the ball, the Cowboys need to add personnel to make the transition to Monte Kiffin's 4-3 defense. 

Most of the pieces are already in place, but they could use an interior pass-rusher to start next to Jay Ratliff. 

Potential targets:

The Cowboys don't have much cap space to work with, so their options are limited. But they could potentially clear more space at some point this offseason. 

Releasing Doug Free, who doesn't have a guaranteed starting job, would open up about $8 million in cap space.

For the right price, Gosder Cherilus would be a nice addition at right tackle. Cheaper options would include Sean Locklear and Barry Richardson.

For the defensive line, Desmond Bryant would be a great fit at tackle. Jason Jones and Sen'Derrick Marks are two other reasonably priced options.

Salary cap space: $2.5 million

Denver Broncos

Primary needs:

How dominant could Von Miller be with some support from the defensive line? That's what the Broncos hope to find out in 2013.

They'll likely add two new starting defensive tackles this offseason, with at least one coming from free agency. 

The Broncos are also in the market for some upgrades in the secondary. 

They need to add some depth at cornerback and may also look for an upgrade at strong safety. 

Potential targets:

The Broncos don't have a ton of cap space, so they'll need to spend their money wisely. 

Antonio Johnson, Jason Jones and Shaun Cody are a few reasonably priced veteran options at defensive tackle. 

Ronde Barber would be an intriguing option at safety if the Broncos can lure him away from Tampa. If he's interested in chasing a ring, the Broncos may be able to get him at a reduced price. 

Some cheap options at cornerback include Stanford Routt, A.J. Jefferson and Darius Butler.

Salary cap space: $12.5 million

Detroit Lions

Primary needs:

Re-signing Cliff Avril would be the ideal first move of free agency for the Lions, but if he departs, it creates a gaping hole at defensive end. Without Avril, the Lions may need to find two new starting ends through free agency and the draft. 

The Lions also need to upgrade the secondary. Cornerbacks Bill Bentley, Jonte Green and Chris Greenwood simply aren't going to get it done in a division with Jay Cutler and Aaron Rodgers. 

On offense, the Lions needs to add another weapon for Matthew Stafford. 

Ideally, they'll find a receiver to compete with Nate Burleson for playing time opposite Calvin Johnson.

Potential targets:

The Lions don't have the money to make a splash, but they can afford to add a few role players. 

John Abraham could potentially be a cheap veteran to plug in at one of the defensive-end spots. Other options include Juqua Parker and Kyle Moore.

The Lions will have plenty of options at cornerback, with guys such as Aaron Ross and Drayton Florence likely available for a reasonable price. 

At wide receiver, the Lions might take a chance on a cheap veteran such as Randy Moss or Michael Jenkins.

Salary cap space: $7.5 million

Green Bay Packers

Primary needs:

James Starks appears to be the Packers' best option at running back, but he's hardly anything to get excited about. 

If the Packers are to remain one of the most dangerous offenses in the league, they need to become more than just The Aaron Rodgers Show.

Adding a running back this offseason is a must. 

To help both Rodgers and the running game, the Packers also need to find a replacement for Jeff Saturday at center. 

The release of Charles Woodson opened up a hole in the secondary. Morgan Burnett is versatile, so Woodson's replacement could come in the form of a strong or free safety.

Potential targets:

The Packers have money to spend, so they have the ability to target some big names. 

Steven Jackson and Michael Turner are two intriguing options at running back. Both are at the end of their careers, but the Packers have the depth at the position to keep their workload down. 

Todd McClure is the best available option at center, although the Packers might have to battle the Falcons, who may try to re-sign him. 

Brad Meester and Chris Spencer are two other veteran options at center. 

The Packers could be in the mix to sign Ed Reed if he doesn't wind up back in Baltimore. Kenny Phillips, Dashon Goldson and Adrian Wilson are other possibilities at safety.

Salary cap space: $20.6 million

Houston Texans

Primary needs:

The Texans need to aggressively fill some holes to make a serious run at the Super Bowl in 2013. 

The top priority should be to address the right side of the offensive line. After losing Eric Winston last offseason, Derek Newton proved to be a significant downgrade at right tackle. 

The Texas should also help Matt Schaub out by adding another weapon in the passing game. Andre Johnson can't continue to carry the receiving corps on his own. 

Wade Phillips also needs another pass-rusher to work with on defense. 

Connor Barwin, who is now a free agent, Brooks Reed and Whitney Mercilus failed to fill the shoes left by Mario Williams. 

A free safety to replace free agent Glover Quin is also a must. 

Potential targets:

Sebastian Vollmer would be an ideal fit at right tackle, but the price tag may be too much for the Texans. 

If they can't swing a deal for Vollmer, they may have to dip into the next tier of linemen and target a guy like Sam Baker or Sean Locklear.

If healthy, Austin Collie would be a great No. 2 receiver next to Andre Johnson. Jerome Simpson and Mohamed Massaquoi are two other cheaper options. 

Quentin Groves and Calvin Pace are two veteran options to add depth at linebacker. 

The Texans may be willing to spend the most money at free safety, in which case Dashon Goldson and Charles Woodson would be two potential targets. 

Salary cap space: $9.1 million

Indianapolis Colts

Primary needs:

The Colts have gaping holes all over on the defensive side of the ball.

How they address free agency could hinge on how much they trust Jerry Hughes to take over a starting role at linebacker. If they don't view him as a starter, they'll need to spend money to bring someone in. 

General manager Ryan Grigson also needs to add the personnel for Chuck Pagano to properly run his hybrid defense. 

This means adding versatile linemen who can play end or tackle in the 3-4 scheme and also a true nose tackle. 

On offense, the Colts need to add another playmaker for Andrew Luck.

Ideally, they'll find someone who can line up in the slot. Reggie Wayne took over the primary slot receiver role this year, but he's at his best on the outside.

The Colts also need to upgrade Luck's protection, especially on the right side of the offensive line.

Potential targets:

Connor Barwin, Cliff Avril and Paul Kruger should all be high on the Colts' wish list as 3-4 outside linebackers. Kruger played under Pagano in Baltimore.

Another former Raven, Cary Williams, should be an option at cornerback. 

Wes Welker would be an ideal fit as the slot receiver in Indy. Danny Amendola would also be a good fit.

Phil Loadholt, Andre Smith, Eric Winston and Sebastian Vollmer are all quality right tackles on the market. The Colts have money to spend and should be able to land one of the four. 

Salary cap space: $42.7 million

Jacksonville Jaguars

Primary needs:

Adding Jason Babin during the season was a step in the right direction, but the Jaguars' most glaring need is still the defensive line. 

Signing a high-profile pass-rusher should be their top priority this offseason. 

The Jaguars are also desperate for help at cornerback, with only two corners currently under contract for 2013.

The recent release of Dawan Landry also opened up a gaping hole at strong safety. 

The Jaguars also need to improve the support around Blaine Gabbert. 

A significant upgrade is needed at right tackle, and it wouldn't hurt to add another option at receiver. 

Potential targets:

Osi Umenyiora and Cliff Avril should be the Jaguars' top targets at defensive end. John Abraham and Michael Bennett are other options. 

With plenty of cap space available, the Jaguars should be able to land one of the top defensive ends.

Cornerbacks such as Chris Houston, Aqib Talib and Antoine Cason should be on the Jaguars' radar. 

They would all be upgrades and are also young enough to contribute for the next three to five years. 

Gosder Cherilus and Eric Winston would be ideal targets at right tackle. If the Jaguars are looking to spend slightly less money on the position, Sam Baker or Winston Justice could be options. 

Salary cap space: $34.8 million

Kansas City Chiefs

Primary needs:

Kansas City has already done more this offseason than any team in the league, but some glaring holes still exist. 

The Chiefs have some of the better linebackers in the game, but they need to support them by upgrading the defensive line. 

Just imagine the damage Tamba Hali and Justin Houston could cause with a more consistent performance from the linemen in front of them.

On the offensive side of the ball, the most glaring hole is at right tackle, but they will likely address that by drafting Luke Joeckel or Eric Fisher No. 1 overall and moving Branden Albert to the right side. 

An upgrade at one of the guard positions is also needed if Ryan Lilja is not re-signed.

Potential targets:

Ty Warren and Kenyon Coleman are two veterans who should be reasonably priced upgrades at defensive end. Chris Canty, who previously played in the 3-4 defense in Dallas, is also an option. 

The Chiefs may not be able to afford to re-sign Lilja. But a number of other free agents would be upgrades over their in-house replacement options. Doug Legursky and Antoine Caldwell are two possibilities who would cost very little.

Salary cap space: $10.3 million

Miami Dolphins

Primary needs:

If the Dolphins want to keep Ryan Tannehill upright in 2013, they need to either re-sign Jake Long or find a suitable replacement. Jonathan Martin simply isn't going to get the job done if he's their best option at left tackle. 

Adding another weapon for Tannehill to work with is also a top priority. They'll definitely add a receiver but may be in the market for a tight end as well.

The Dolphins don't have too many holes on defense, but they do need to find at least one starting cornerback. 

Potential targets:

Mike Wallace, who could already have a tentative agreement to sign with the Fins, and Greg Jennings are the two biggest names on the free-agent market and one of them should land in Miami. 

If Long isn't re-signed, the Dolphins should do whatever it takes to sign Sebastian Vollmer. He may be the only other lineman on the market capable of being an above-average left tackle. 

There are plenty of cornerbacks available, including Dominique Rodgers-Cromartie and Antoine Cason. The Dolphins should have no problem finding a quality starting corner. 

Salary cap space: $32.3 million

Minnesota Vikings

Primary needs:

The top priority for the Vikings is re-signing Phil Loadholt, who has been one of the top right tackles in the game over the past few seasons. 

After securing Loadholt, the Vikings need to address the situation at receiver. 

They can't reasonably expect Christian Ponder to continue to develop with Greg Childs and Jarius Wright as his top targets. A big-name free agent receiver should definitely be a target for the Vikings.

On the defensive side of things, the Vikings have some serious question marks at linebacker. Aside from Chad Greenway, there isn't much set in stone. 

In the secondary, an upgrade at strong safety should also be a priority.

Potential targets:

With a decent amount of cap space, the Vikings should be able to fill the majority of their holes. 

Greg Jennings and Mike Wallace should be their top priorities. General manager Rick Spielman needs to find a way to get one of them to Minnesota.

Daryl Smith would be an excellent addition at linebacker, and he could play either inside or the weak-side position. Brian Urlacher would be another intriguing possibility if the Vikings could lure him away from Chicago. 

There isn't a lot to choose from at strong safety, but LaRon Landry would be an ideal fit. Adrian Wilson would be another decent option. 

Salary cap space: $20.3 million

New England Patriots

Primary needs:

The Patriots' top priority needs to be re-signing their own guys. 

Wes Welker is their most high-profile free agent and should be re-signed, but their most valuable free agent might be Sebastian Vollmer. 

The Patriots offensive line would take a significant hit if Vollmer is allowed to walk. 

Once their own guys are re-signed, the Patriots still have a few holes to address. 

Even with Welker on board, Tom Brady needs another weapon on offense. Brandon Lloyd and Matthew Slater simply aren't going to get it done as No. 2 and No. 3 options. 

On the defensive side of the ball, the Patriots need to add depth at cornerback. Re-signing Aqib Talib is an option, but they would be wise to not to overpay for his services. 

Potential targets:

With plenty of cap space, the Patriots can target just about anyone they'd like to bring aboard. 

The possibility of adding a big-name receiver such as Greg Jennings is intriguing. But they'll more likely settle for a second-tier guy such as Jerome Simpson, Mohamed Massaquoi or Brandon Gibson.

If the Patriots are only looking for a nickel back, rather than a starting corner, Sheldon Brown could be the ideal target. Derek Cox and Tracy Porter are also possibilities. 

Salary cap space: $26.2 million

New Orleans Saints

Primary needs:

The Saints aren't going anywhere fast until they add the personnel necessary to run the 3-4 defense. As a result, this offseason is all about the defensive side of the ball.

The first priority is adding a pass-rusher at outside linebacker to pair with Will Smith. Jonathan Vilma would be their best option right now, but he is much better suited to play inside. 

A nose tackle is also needed, unless they're willing to rely on Akiem Hicks to step into a full-time role. 

Potential targets:

As of late Monday night, the Saints are over the salary cap but they could create some space by parting with Will Smith, Jonathan Vilma or Roman Harper. 

But unless the Saints were to cut all three, they still won't have much money to spend. 

With limited resources, the Saints can really only try to add depth, rather than impact players. 

Calvin Pace and Darryl Tapp could be cheap options at outside linebacker. 

At nose tackle, Shaun Smith and Antonio Johnson are two of the few options they may be able to afford.

Salary cap space: none

New York Giants

Primary needs:

The Giants don't have too many glaring holes, but they do need to find a few upgrades in the front seven. 

Middle and weak-side linebacker are the two most obvious areas of need and have been for the past few seasons. 

On the defensive line, Justin Tuck and Jason Pierre-Paul are among the best pass-rush duos in the league, but depth is lacking. 

The Giants likely won't make many moves on offense, but they do need to address tight end. Ideally, Martellus Bennett will re-sign. But if he's gone, they need to find a suitable replacement.

Potential targets:

With limited cap space, the Giants can't afford to be too aggressive in free agency. 

Brian Urlacher would be an interesting possibility if they can make the money work, but he may be too expensive to even pursue. 

A more realistic option at middle linebacker may be Bradie James or Keith Brooking.

Along the defensive line, an inexpensive veteran such as Amobi Okoye or Shaun Cody may be their best option. 

If Bennett isn't re-signed, there are plenty of options at tight end, but most would be out of the Giants price range. Anthony Fasano or Delanie Walker may be their best options at a realistic price. 

Salary cap space: $4.1 million

New York Jets

Primary needs:

As bad as the Jets' offense looked in 2012, the defense needs to be the focus of the offseason. 

The Jets' already anemic pass rush is losing Calvin Pace and they don't have any suitable replacements on the roster. They should try to add a pass-rusher in free agency and in the draft. 

If Darrelle Revis is traded, the Jets will also need to add another cornerback. Kyle Wilson could step into a starting role, but even then a nickel back would be needed.

To fix the ailing offense, the Jets need to add more playmakers. Adding a starting running back is the top priority on offense, but another weapon in the passing game is also needed.

The Jets may also be in the market for a right tackle. Austin Howard was tendered as a restricted free agent, but he struggled in pass protection a season ago. 

Potential targets:

Due to the fact the Jets have some holes that must be filled, they can't afford to spend their limited resources on one or two impact players. 

They may need to allocate the most money to the running-back position. A veteran such as Ryan Grant or Cedric Benson could fill the hole in the short term for a reasonable price. 

Considering what's available in their price range, the Jets probably aren't going to get an impact pass-rusher. Taking a chance on a veteran such as Quentin Groves may be their best option. 

At cornerback, a veteran such as Sheldon Brown or Terrence McGee would be capable of stepping into a starting role or playing the nickel-back position. 

Salary cap space: $6.6 million

Oakland Raiders

Primary needs:

Aside from Lamarr Houston, there's not much to get excited about on the Raiders defense. The majority of their best players from a season ago—Phillip Wheeler, Desmond Bryant, Richard Seymour—will be signing elsewhere this offseason. 

As a result, every position on the defensive side of the ball should be considered a need with the possible exception of safety.

The Raiders also need to upgrade the offensive line and add at least one more weapon for Carson Palmer and Terrelle Pryor. 

Potential targets:

The Raiders' first move should be to cut Carson Palmer, which would nearly triple their cap space. But if Palmer remains on board, they can't afford to do much in free agency. 

Cary Williams and Jacob Lacey could be relatively inexpensive options at cornerback. 

At defensive tackle, veterans Shaun Smith and Ron Edwards could be cheap options as a starter at nose tackle next to Tommy Kelly.

Dallas Clark could be an option for the Raiders if they decide to upgrade their tight-end situation. He may be a safer bet than any of the receivers in their price range.

Along the offensive line, they'll likely only be able to afford low-level free agents such as Ryan Harris or Tyler Polumbus.

Salary cap space: $6.9 million

Philadelphia Eagles

Primary needs:

Just two years after bringing in Nnamdi Asomugha and Dominique Rodgers-Cromartie, the Eagles are rebuilding their secondary once again. 

They need to find a starter at cornerback to pair with Asomugha (assuming he stays in Philly, which is up in the air) and potentially two new starters at both safety positions. 

The Eagles also need to address the front seven to put the personnel in place for their transition to the 3-4 defense.

On offense, the Eagles might be interested in adding an insurance policy behind injury-prone left tackle Jason Peters. However, this is a position that could be addressed in the draft. 

Chip Kelly will also be in the market for a few playmakers to fit his scheme. This could come in the form of running backs or receivers. 

Potential targets:

The Eagles have plenty of cash to spend, so expect them to make a few big-name signings early in the free-agent process. 

At cornerback, Brent Grimes would be an ideal fit. He's a legitimate No. 1 corner when healthy and would take some pressure off Asomugha.

Dashon Goldson, LaRon Landry and Kenny Phillips should all be high on their list of potential safeties. 

If the Eagles choose to address the offensive line via free agency, Sebastian Vollmer should be a target. He's capable of excelling at either left or tight tackle, giving them some versatility with how they shuffle their line. 

Kelly is going to bring in at least one playmaker for his system. Danny Amendola and Austin Collie would both fit nicely into his system, but both have health concerns. 

Josh Cribbs and Ted Ginn are two other versatile playmakers who may interest Kelly.

Salary cap space: $29.8 million

Pittsburgh Steelers

Primary needs:

Mike Wallace is unlikely to be re-signed, which means the Steelers need to find another weapon for Ben Roethlisberger elsewhere. 

Roethlisberger has always wanted a big receiver, and this could be the time to find him one to pair with Emmanuel Sanders and Antonio Brown. 

Due to the departure of James Harrison, the Steelers need to replenish the depth at linebacker, but they don't necessarily need to find a starter. 

Jason Worilds is capable of stepping into a starting role, so the Steelers may only be in the market for a backup. 

The Steelers may also consider adding a nose tackle, depending on how they feel about the future of Steve McLendon and Alameda Ta'amu. 

Potential targets:

With limited cap space, the Steelers can't afford to do much this offseason. 

Michael Jenkins and Chaz Schilens could be cheap options at receiver if they're simply looking to add to their depth. 

If the Steelers are interesting in some veteran depth at linebacker, Calvin Pace and Quentin Groves would be two relatively inexpensive options. 

Aubrayo Franklin and Isaac Sopoaga are two veteran options at nose tackle. 

Salary cap space: $5.7 million

San Diego Chargers

Primary needs:

The Chargers need to protect Philip Rivers.

According to Pro Football Focus, Rivers was pressured on 38.2 percent of his drop-backs this past season, the third highest rate in the league. 

Adding at least one starting offensive lineman in free agency is an absolute must. 

The Chargers are equally desperate for help in the secondary.

Veteran cornerbacks Antoine Cason and Quentin Jammer are both unrestricted free agents and are expected to sign elsewhere. 

Potential targets:

The Chargers need to decide if they want to make a splash with one big signing or spread their limited resources around. 

If they want to solve their offensive-line issues quickly, adding Sebastian Vollmer or Eric Winston at right tackle would be the way to go. But either one would eat up a significant chunk of their available cap space. 

Barry Richardson or Jeremy Trueblood would be much cheaper options, but wouldn't necessarily be significant upgrades. 

At cornerback, the Chargers probably need to choose quantity over quality. Bradley Fletcher, E.J. Biggers and Kelvin Hayden are all reasonably priced possibilities. 

Salary cap space: $9.5 million

San Francisco 49ers

Primary needs:

The 49ers' Super Bowl performance demonstrated just how porous their secondary can be against the elite teams in the league. It's an area that was easily covered against their NFC West opponents, but they were exposed at times in the playoffs. 

They'll need to replace free-agent Dashon Goldson and add some depth at cornerback. 

The 49ers could also use an upgrade at nose tackle, where they didn't really have a full-time starter in 2012. Just imagine what their linebackers could be capable of with more support up front. 

San Francisco also needs to replace David Akers at kicker.

Potential targets:

If the 49ers want to make a splash, they'll target Ed Reed. He may not have much left, but for a season or two, he would be the leader of the 49ers secondary. 

Another more realistic option at free safety would be Kenny Phillips.

Casey Hampton would be a perfect addition at nose tackle. He can only play about 50 percent of the snaps at this stage of his career, but the 49ers showed last year that they can remain productive with a rotation at nose tackle. 

Phil Dawson would be the ideal addition at kicker if he doesn't re-sign in Cleveland.

Salary cap space: $5.5 million

Seattle Seahawks

Primary needs:

The Seahawks need to upgrade the protection for Russell Wilson.

Breno Giacomini isn't getting the job done at right tackle and needs to be moved to a backup role. 

Seattle also has a few free agents that will need to be replaced on the defensive side of the ball if they're not re-signed. 

The departure of Alan Branch would create a hole at defensive end. Losing Leroy Hill would also open up a gap at weak-side linebacker.

Potential targets:

Sebastian Vollmer would also be a great fit at right tackle in Seattle. Gosder Cherilus, Phil Loadholt and Eric Winston are other options. 

The Seahawks have plenty of reasonably priced options at defensive tackle. Chris Canty, Sedrick Ellis and Richard Seymour would all be perfect fits.

Depending on how Percy Harvin's contact is structured, however, the Seahawks may not have as much cap space with which to work.

Salary cap space: $17.5 million (pre-Percy Harvin contract)

St. Louis Rams

Primary needs:

This Rams' offseason needs to be all about Sam Bradford. 

The top priority is keeping Bradford upright by finding multiple upgrades on the offensive line. Rodger Saffold and Harvey Dahl's jobs should be safe, but the other three spots are up for grabs. 

Bradford also needs another weapon in the passing game, especially if free agent Danny Amendola signs elsewhere. 

The Rams also need help in the defensive secondary. 

Quintin Mikell was recently released (via Yahoo! Sports), opening up a glaring hole at strong safety. 

They could also use an upgrade at free safety and some depth at cornerback. 

Potential targets:

Re-signing Amendola should be the first order of business, but they shouldn't overpay for the injury-prone receiver. 

If Amendola gets away, Jerome Simpson, Early Doucet and Julian Edelman could be some relatively cheap replacements. 

On the offensive line, signing Jake Long should be the top priority. He would be plugged in at left tackle, bumping Saffold to the right side and giving the Rams two quality bookend tackles. 

If they can't land Long, Phil Loadholt and Sebastian Vollmer are the next best options. 

At safety, Adrian Wilson could be a relatively inexpensive replacement for Mikell at strong safety.

Salary cap space: $14.8 million

Tampa Bay Buccaneers

Primary needs:

The Buccaneers overpaid for free-agent cornerback Eric Wright a season ago, and now they're in the same position they were last offseason. 

Wright, who counts for $7 million against the cap, is a candidate to be released. But even if he stays, the Buccaneers need to find an upgrade at cornerback.

The Bucs could also use a run-stuffing nose tackle to pair with Gerald McCoy on the interior defensive line. 

On offense, Josh Freeman needs another weapon. 

Dallas Clark didn't pan out as a free-agent acquisition last year, so they're back in the market for another tight end.

Potential targets:

The Bucs want to compete in 2013, so they will likely target some veteran free agents. 

If healthy, Brent Grimes would be the best option at cornerback. It would also look good to steal him from within the division, leaving the Falcons scrambling to find a replacement. 

Other veteran cornerback options include DeAngelo Hall and Antoine Cason.

There are a number of relatively inexpensive defensive tackles on the market this year. Alan Branch, Ma'ake Kemoeatu and Antonio Johnson would all fit nicely in Tampa. 

At tight end, Martellus Bennett would be the ideal target if he doesn't re-sign with the Giants. He's one of the few tight ends on the market that can help out as a receiver and a blocker. 

Ben Watson would be a strong backup plan if they can't land Bennett.

Salary cap space: $31 million

Tennessee Titans

Primary needs:

Chris Johnson deserves more help than he's received the past few years, especially from the interior offensive line. 

Finding an upgrade at right guard is a must, and the retirement of Steve Hutchinson opens up a hole at left guard as well.

The Titans also need to find an upgrade at tight end. Free agent Jared Cook has never lived up to expectations and probably won't be worth the contract he'll command on the open market.

On the defensive side, the Titans secondary could use work, especially at free safety. 

Michael Griffin has been a consistent disappointment, and it might be time to find a replacement. 

Potential targets:

Andy Levitre is arguably the best guard on the market and should be priority No. 1. 

If they can't land Levitre, Brandon Moore would be a decent fall-back plan.

Dallas Clark could be an option at tight end. He isn't what he used to be in Indianapolis, but his veteran presence on offense could certainly help Jake Locker. Dustin Keller and Ben Watson are two other possibilities. 

Salary cap space: $19.9 million

Washington Redskins

Primary needs:

This offseason needs to be all about protecting Robert Griffin III. 

Veteran right tackle Jammal Brown missed the entire 2012 season and likely won't be re-signed. 

The Redskins need to find a suitable replacement, because Tyler Polumbus simply didn't get the job done last year.

Griffin could also use another weapon in the passing game. Pierre Garcon can only do so much, and Santana Moss turns 34 in June.

On the defensive side of the ball, the secondary could use some work. A safety who excels in coverage should be a top priority.

Potential targets:

The Redskins were over the cap as of Monday morning, but by parting ways with DeAngelo Hall (via ESPN.com), they cleared up a decent amount of cap space. 

They still lack the resources to make any significant changes, but they could afford to bring in a few mid-level free agents.

On the offensive line, Sean Locklear and Barry Richardson would be two reasonably priced options to plug in at right tackle. 

In the secondary, Kenny Phillips would be an ideal upgrade at free safety but might be out of the price range. Former Dolphin Chris Clemons might be a more realistic target.

The Redskins have also been linked to Aqib Talib, who would be a replacement, although not necessarily an upgrade, for Hall.

Salary cap space: $7.1 million
