Probably Barr, M. Jones, and James. On the OL, there's going to be Capella and X-man. Probably a few others I can't recall. At WR, I doubt it. TE, maybe Young, but I don't know if he played in '11.
Defensively, Owa, Marsh, Kendricks, McDonald...maybe a couple more. I'd say Riley and Zumwalt, but who knows if they play again due to all the concussions.
