• The obvious upgrade at center by adding Alex Mack (which has helped and justified the resigning of Chris Chester)

• The addition at DL of Dwight Freeney (locker room leader/mentor) and Courtney Upshaw (making big plays) who have both won SB rings (only players on our roster with rings)

• Sanu Canoe and Aldrick Robinson have made major contributions, Sanu's blocking is undervalued in the run game

• With others facing injuries, Wheeler and LaRoy Reynolds have contributed at LB when they get snaps

I think these signings have helped keep our team focused and have them sticking together as DQ wanted. With players like Freeney and Upshaw who have won SBs, to backup/PS types like Robinson and Reynolds, and major contributors like Mack and Sanu, our FA signings have collectively been a success despite many of them going down this season (Shelby, Clayborn, Spoon, etc.).

EDIT: Gabriel was claimed off waivers, so not a FA signing. Still an excellent claim.
