With training camps winding down, I've found time to update rosters and put together team-by-team reference material for unrestricted free agency.
The names below match official NFL counts.
These are for players with at least four accrued NFL seasons whose contracts expired following the 2010 season. I've added comments for each team.
Re-signed (8): Ben Graham, Matt Ware, Hamza Abdullah, Ben Claxton, Lyle Sendlein, D'Anthony Batiste, Deuce Lutui, Stephen Spach.
New to team (7): Chansi Stuckey, Richard Marshall, Daryn Colledge, Nick Eason, Stewart Bradley, Floyd Womack, Jeff King.
Still unsigned (3): Alan Faneca, Jason Wright, Bryan Robinson.
Signed elsewhere (5): Steve Breaston (Kansas City), Gabe Watson (New York Giants), Ben Patrick (Giants), Trumaine McBride (New Orleans), Alan Branch (Seattle).
Comment: Sendlein, Colledge and Bradley were the big signings. Marshall provides needed depth at cornerback. Faneca and Wright announced their retirements. The Cardinals weren't aggressive in trying to re-sign the players they lost to other teams. The biggest move Arizona made, acquiring Kevin Kolb from Philadelphia, did not involve a UFA.
San Francisco 49ers

Re-signed (4): Ray McDonald, Tony Wragge, Dashon Goldson, Alex Smith.
New to team (5): Braylon Edwards, Jonathan Goodwin, Donte Whitner, Carlos Rogers, David Akers.
Still unsigned (5): Brian Westbrook, Troy Smith, Demetric Evans, William James, Barry Sims.
Signed elsewhere (6): David Baas (Giants), Travis LaBoy (San Diego), Jeff Reed (Seattle), Aubrayo Franklin (New Orleans), Takeo Spikes (San Diego), Manny Lawson (Cincinnati).
Comment: Re-signing McDonald signaled Franklin's departure. Getting Goldson back on the relative cheap was a victory. The 49ers wanted to keep Baas, but not at the price he commanded. The team thinks NaVorro Bowman has a bright future in Spikes' old spot at inside linebacker. Lawson wasn't strong enough as a pass-rusher to stick around. Safety depth is improved.
Seattle Seahawks

Re-signed (7): Raheem Brock, Junior Siavii, Brandon Mebane, Leroy Hill, Matt McCoy, Michael Robinson, Kelly Jennings.
New to team (8): Branch, Zach Miller, Robert Gallery, Jimmy Wilkerson, Atari Bigby, Sidney Rice, Tarvaris Jackson, Reed.
Still unsigned (7): Jay Richardson, Craig Terrill, Chester Pitts, Brandon Stokley, Ruvell Martin, J.P. Losman, Lawyer Milloy.
Signed elsewhere (8): Will Herring (New Orleans), Olindo Mare (Carolina), Matt Hasselbeck (Tennessee), Chris Spencer (Chicago), Jordan Babineaux (Tennessee), Sean Locklear (Washington), Amon Gordon (Kansas City), Ray Willis (Washington).
Comment: Adding Jackson as the starting quarterback was the most significant move for the 2011 season. Mebane was the most important re-signing for the longer term. Hill was a bargain relative to how he's playing right now. Miller and Rice were the types of young, talented players who rarely change teams in free agency. The Seahawks were outbid for Herring and Mare. Can street free agent David Vobora fill some of the void Herring left?
St. Louis Rams

Re-signed (2): Adam Goldberg, Gary Gibson.
New to team (9): Daniel Muir, Quinn Ojinnaka, Harvey Dahl, Ben Leber, Zac Diles, Jerious Norwood, Cadillac Williams, Quintin Mikell, Mike Sims-Walker.
Still unsigned (5): Chris Hovan, Michael Lewis, Darcy Johnson, Clifton Ryan, Mark Clayton.
Signed elsewhere (4): Daniel Fells (Denver), Laurent Robinson (San Diego), Derek Schouman (Washington), Kevin Dockery (Pittsburgh).
Comment: Dahl and Mikell were the big additions. Clayton could return if and when his surgically repaired knee allows. Sims-Walker is a wild card. The team didn't flinch when any of its own UFAs signed elsewhere. Most of the moves made on defense were designed to improve St. Louis against the run. Remember that newcomer Justin Bannan was not a UFA. Denver released him.
