I don't get why people are so negative about full contact during scrimmages? Walton probably gets tackled 20-30 times a practice, each of the WRs and TEs takes 5+ hits from guys coming downhill, often times exposed. How often do QBs get injured, even in game time? I would bet it's much less than RBs, TEs, OL, WRs. If you have 3-4 guys who are interchangeable, then you need to evaluate their abilities by simulating the game as best as possible.
Pete, it's pretty clear your money is on Shirreffs. All the players seem to think it's Shirreffs or Rosier from their answers during media Q&A. Does anyone really think Perry can step in next month and take that starting role from 2 guys who are competing like crazy and have been on campus 2-3+ years?
