Assuming this is just football, otherwise Bernard King and no one else is even close.
Peyton really only had half a season. Erik Ainge beat Florida in his 3RD GAME as a Vol. Justin Hunter looked like a Heisman winner in his first few games. Lewis was a beast. Berry was Berry.
But even though he wasn't eligible, I did see Condredge Holloway in a few JV games. He was fantastic, and there is no doubt he would have been the starter if Freshmen had been eligible at the time. So that's who I'm going with.
