Don't get too freaked out by the spring game OL. There are only 2 guys capable of playing OT (Alesana and Stringer) on the roster now, and they will not be participating. Prince will have to roll out 4 guys at OT who have no business trying to block Jackson and Campbell, etc. It could get ugly.
I think the 4 most likely guys to play OT in the spring game (depending on how the draft goes) would be
1. Spexarth, who is horrible at tackle and gets beat at least 80% of the time
2. Zach Lucas, hard-working walkon who belongs on the scout team and deserves our love, much like Rudy
3. Brock unruh, a guard
4. eh, Derek Meyer perhaps, who showed last year that he isn't god-awful, but he really can't consistently get the job done in space and thus was moved inside to guard.
Right now, there are a total of 10 O-Linemen who are mostly healthy enough to suit up for the spring game. If anyone gets hurt between now and the game, some guys will have to play both ways or they will have to "borrow" some DL and slap them on the OL. Also, don't be too hard on Rooker -- he will be playing injured.
