IMO the only QBs I would take in the 3rd would be Campbell, Frye or Walters. Campbell shouldnt be there, Frye should be there, and Walters should be the best prospect in that area. Walters has had good workouts and out of the three of them, while he has the most risk to him because of his injury, he also has the most upside skillwise.
After seeing Orton play live against a good defense in Penn State, I jumped right off the bandwagon. I thought at that time he was the top QB prospect but after watching him play, blech. His stats were inflated when they were undefeated and Im glad Purdue went on a losing streak and his numbers went down.
We dont need to draft another AJ Feeley, and the only guy who has the physical talent to be better than AJ that might be left in the 3rd would be Walters.
