Pretty much what I've been saying since last year. I don't think the reasoning given for not rotating OL at least a little bit makes much sense. If "chemistry" is the main reason given, what happens when there are injuries that force you to rotate? And I think we've seen both last year and this year that the "gap" between the first and second team isn't as much as it's being made out to be. If we can take three guys who started as walk-ons - only one of whom was expected to be a starter before the year - and put up 200+ rushing yards against maybe the best defensive line we'll see all year including three potential NFL guys, I think that kind of shows the depth we have and how good these guys can be given a chance.
Here's the OL depth chart from early in fall camp:
LT - Gates, Gaylord
LG - Foster, Barnett
C - Utter, Decker
RG - Farmer, Whitaker
RT - Knevel, Hahn
And here's where it was (roughly) for most of the Illinois game (after Knevel went out) - changes highlighted:
LT - Gates, Gaylord
LG - Hahn, Barnett
C - Utter, Decker
RG - Whitaker, Hannon
RT - Conrad, Farniok
