2011 Free Agency: Star rating is out of five. Age listing as of Sept. 1, 2011.
Doug Free, OT, Cowboys. Age: 27. Re-signed with Cowboys (4 years, $32 million; $17 million guaranteed)
Doug Free played exceptionally well in his first year as Dallas' left tackle. He'll command a huge contract this offseason.
Willie Colon, OT, Steelers. Age: 28. Re-signed with Steelers (5 years, $29 million)
Willie Colon missed the entire 2010 season with a torn Achilles, but his recovery apparently has gone pretty well. Colon is an outstanding, Pro Bowl-caliber right tackle, so Ben Roethlisberger would love to have him back.
Marshal Yanda, OT/G, Ravens. Age: 26. Re-signed with Ravens (5 years, $32 million)
Marshal Yanda had a very good season, surrendering only four sacks. He's capable of playing both right tackle and guard effectively, so that versatility should help him this offseason.
After a very sluggish start, Jammal Brown played well down the stretch once he got over his hip surgery.
Matt Light, OT, Patriots. Age: 33. Re-signed with Patriots (2 years)
Matt Light can still be a dependable left tackle, but he's past his prime. He struggled on a few occasions this season, surrendering seven sacks.
Sean Locklear, OT, Seahawks. Age: 30. Signed with Redskins
Sean Locklear is pretty abysmal when it comes to opening up lanes for running backs, but he does a really good job in pass protection. He surrendered only five sacks in 2010 (including the playoffs).
Ryan Harris, OT, Broncos. Age: 26. Signed with Eagles (1 year)
A young, decent, zone-blocking right tackle, Ryan Harris struggled in Josh McDaniels' new offense. Harris will probably be heavily pursued this spring, though he's been injured a lot in the past two years.
Jared Gaither, OT, Ravens. Age: 25. Signed with Chiefs
Jared Gaither is a very talented offensive tackle, but he missed all 2010 with a serious back injury. Back problems don't go away very easily, so it's possible that Gaither may never be 100 percent again.
Max Starks, OT, Steelers. Age: 29.
Max Starks is a starting-quality left tackle. Well, he was before he ballooned up to 400 pounds. Starks lost his job because he wasn't able to work out after suffering a neck injury.
Barry Richardson, OT, Chiefs. Age: 25. Tendered by Chiefs
Barry Richardson is a forceful run-blocker, but an absolute sieve in pass protection.
Langston Walker, OT, Raiders. Age: 31.
Langston Walker tends to struggle in pass protection, but he's a very forceful run-blocker on the right side.
Nick Kaczur, OT, Patriots. Age: 32.
Nick Kaczur played well at right tackle for New England in 2009, but missed all of 2010 with a back injury. It's unclear if he can still be a starter in this league.
Damien Woody, OT, Jets. Age: 33. Announced retirement
Damien Woody's age (34 in November) and injury (torn Achilles) are the reasons why he's only rated two stars. Woody is a tremendous run-blocker and is adequate in pass protection, but his health is an issue.
Ryan O'Callaghan, OT, Chiefs. Age: 28. Re-signed with Chiefs
Ryan O'Callaghan played well in 2009, but barely saw the field this past season because of various injuries.
James Lee (ERFA), OT, Buccaneers. Age: 26.
James Lee supplanted Jeremy Trueblood at right tackle in the middle of the year and did an OK job. He can be upgraded though.
Bryant McKinnie, OT, Vikings. Age: 31.
Bryant McKinnie has immense talent, but he's also a fat, lazy slob. The Vikings cut the soon-to-be 32-year-old McKinnie because he weighed in close to 400 pounds at training camp. He'd be a good addition to a team if he somehow gets his act together, but that's probably not going to happen.
Mark Tauscher, OT, Packers. Age: 34.
Flozell Adams, OT, Steelers. Age: 36.
Jeremy Trueblood, OT, Buccaneers. Age: 28. -- Re-signed with Buccaneers (2 years)
Jeromey Clary, OT, Chargers. Age: 27. -- Re-signed with Chargers (4 years, $20 million)
Mario Henderson (RFA), OT, Raiders. Age: 26.
Brandon Keith (RFA), OT, Cardinals. Age: 26.
Brandyn Dombrowski, OT, Chargers. Age: 26. -- Tendered by Chargers
Shawn Andrews, OT, Giants. Age: 28.
Marc Colombo, OT, Cowboys. Age: 32. -- Signed with Dolphins
Kevin Shaffer, OT, Bears. Age: 31.
Charlie Johnson, OT, Colts. Age: 27. -- Signed with Vikings
Jonathan Scott, OT, Steelers. Age: 28. -- Re-signed with Steelers
