While the next collective bargaining agreement remains in the works, I do expect that Green Bay Packers LG Daryn Colledge will become an unrestricted free agent. He just finished his fifth season, and I think players will be unrestricted after their fourth season. 

I've been grumbling about him for the past couple seasons, but 2010 was his best. It helped a lot that they didn't play him at left tackle. For the first time in the past couple offseasons, I would expect his replacement to be a short-term downgrade.

There's no obvious left guard of the future on the roster. OL T.J. Lang could be an option, or even RT Bryan Bulaga (who played there during the preseason) if they're in the mood to tinker with the offensive line. I'd prefer keeping Colledge over either of those options, though Lang could become a better long-term option.

While they took care of LB A.J. Hawk before the previous CBA expired, they made little effort to sign Colledge. While I think a lack of activity can be proof they aren't going to re-sign a free agent (like DE Cullen Jenkins), that's not as important with Colledge. The Packers were willing to let LT Chad Clifton test the free agent market last year, although they wanted to re-sign him.
