Pat Angerer: Will not win the SLB spot as he's clearly a coverage LB (probably Brackett's projected replacement), so he's not likely to start this year
Kevin Thomas: Out for Season
Brody Eldridge: Unless he bulks up and starts playing LT, he's not going to play other than short yardage situations at FB.
Ricardo Mathews: Should see some PT, but not likely to contribute as much as a starting OG.
Kavell Conner: Probably a special teamer or practice squad player this year.
Ray Fisher: At best a KR/PR, doubt he can win the dimeback spot even with Thomas down for the year.
I'd say McClendon is the clear favorite when not considering Hughes.
