Looney has graded better than Biadasz at Center this season. Looney also can play both Guard positions. I would not be surprised if he could play one of the Tackle positions as well if needed as an emergency. Looney also is a veteran leader who sparks up the team with both his performance on the field, as well with his playfulness in practice but also his spiritual praying as a group.
Joe Looney most definitely needs to be kept, hopefully on a team friendly contract extension. He's that valuable.
