Quarterbacks
Schefter's blog: Market watch
Get the inside scoop from Adam Schefter, who has all the latest player news and notes from around the NFL as teams prepare for the start of free agency. **More ...**
1. Kurt Warner, Cardinals -- Just a question of Warner and Cardinals finalizing a deal.
2. Kerry Collins, Titans -- No team can offer the full package that Tennessee can.
3. Jeff Garcia, Buccaneers -- Would be a perfect stop-gap quarterback for San Francisco.
4. Byron Leftwich, Steelers -- As much as he would like the chance to start, it's going to be tough to land that promise.
5. Rex Grossman, Bears -- Good enough to win an NFC Championship.
Sleeper: J.P. Losman, Bills -- With a change of scenery, maybe his talent can flourish.
Running backs
1. Derrick Ward, Giants -- Hoping to find more of a market than there was last year for his services.
2. Fred Taylor, Jaguars -- Cut last week, he already has visited Buffalo and New England.
3. Maurice Morris, Seahawks -- Seattle would like to keep him and have him compete for starting job.
4. Cedric Benson -- Emerged from the scrap heap to become a possibility for a running-back needy team.
5. Warrick Dunn -- Still produced for Tampa Bay last year and will help some team this year.
Sleeper: J.J. Arrington, Cardinals -- As an added bonus, can help as a return man.
Wide receivers
1. T.J. Houshmandzadeh, Bengals -- Cincinnati is making a last-ditch effort to re-sign him.
2. Laveranues Coles, Jets -- Miami would be a great fit for Coles.
3. Nate Washington, Steelers -- Proved to be enough of a downfield threat that will be attractive to somebody.
4. Michael Clayton, Buccaneers -- Never blossomed the way many thought he would after his rookie season.
5. Marvin Harrison, Colts -- At 36, not what he once was, but still could be a solid No. 3 wideout.
Sleeper: Bobby Engram, Seahawks -- Still can be productive despite his age.
Offensive linemen
1. Jason Brown, Ravens (C-G) -- Would not be surprising to see the Dolphins make a major push for him.
2. Jon Stinchcomb, Saints (T) -- The top tackle free agent has been a full-time starter for Saints.
3. Jeff Saturday, Colts (C) --Colts already have informed him they don’t expect to bring him back.
4. Stacy Andrews, Bengals (T) -- The Bengals' franchise player last offseason, he suffered a serious knee injury this season.
5. Khalif Barnes, Jaguars (T) -- It’s rare that a 26-year-old starting left tackle hits the market.
Sleeper: Ray Willis, Seahawks -- Pay attention to his name; the contract he lands will be eye-opening.
Defensive linemen
1. Albert Haynesworth, Titans (DT) -- If it goes the way he wants, he will become football’s first $100 million defensive player.
2. Chris Canty, Cowboys (DE) -- Dallas can't afford him, and other teams are after him.
3. Antonio Smith, Cardinals (DE) -- High-motor pass-rushers always will have a market.
4. Colin Cole, Packers (DT) -- With so many teams switching to the 3-4, Cole will be in demand.
5. Bertrand Berry, Cardinals (DE) -- An oldie but goodie, Berry still can rush the passer.
Sleeper: Kevin Carter, Buccaneers (DE) -- A good player to have on the line and in the locker room.
Linebackers
1. Ray Lewis, Ravens -- Make no secret, he’s going to the highest bidder, either the Ravens or the Jets.
2. Bart Scott, Ravens -- Wherever Lewis doesn’t wind up is where Scott likely will.
3. Jonathan Vilma, Saints -- New Orleans would love to be able to afford to bring him back.
4. Michael Boley, Falcons -- With the emergence of the 3-4, Boley will have plenty of suitors.
5. Derrick Brooks, Buccaneers -- A trusted veteran of Tampa Bay's defense, he could help a team on run downs.
Sleeper: Angelo Crowell, Bills -- Good enough to help somebody.
Defensive backs
1. Bryant McFadden, Steelers -- The only unrestrictred free-agent starter off Pittsburgh’s championship defense.
2. DeAngelo Hall, Redskins -- Washington is determined not to let him get away.
3. Ron Bartell, Rams --Rams have been trying for days to resign him before free agency.
4. Jabari Greer, Bills -- Has been waiting to test the free-agent market.
5. Jermaine Phillips, Buccaneers (S) -- Packs a wallop.
