I guess it really depends on how you classify greatness. If you look at wins, then Schor stands alone. Winning 26 straight, two CAA championships, and a national title in two years as a starter is just about as impressive as it gets. To be fair though, Schor did have the luxury of an amazing defense.

If you are looking at dominance and the ability to impact a game, Vad and Rodney are neck and neck. Both were dynamic play makers who could put a team on their shoulders. Facing a 4th and 3 though with a season on the line, give me Rodney.
