Just saw this article detailing some problem on the o-line for the Packers. It seems they have had problems with their guards all year as well.
I especially liked this user comment:
In every game that the Packers have had trouble this season, and Daryn Colledge has been on the Line, the Packers have stumbled greatly or been beaten. He’s had maybe ten, or eleven, good plays all season. He was instantly overmatched against the Redskins and will be again, if they leave him in there.
