I'll put it this way, Tebow might not even be the 4th best passer in the Big 12, but I have confidence that he will show that he would be the best or second best quarterback. There is a lot more to quarterbacking than passing the ball. Many college QBs found this out when transitioning to the NFL, or when playing teams outside of their conference. Overall quarterback ratings are hard to compare since there is no statistic in the QB rating for rushing, leadership, win percentage, etc.
