If I had to take a QB in this class, and I really don't, I'd take Barkley. Great leader for the Trojans. Very knowledgeable about the game, and proved it in a "pro" offense at USC. But, he lacks accuracy and velocity on difficult throws. At best, you're getting a Dalton type with him.
It's funny that the one QB who has this ridiculous legendary status is Jim Kelly. Who is about the money more than anyone. He even robbed from local businesses, and nobody bats an eye.
