Far from an easy winner. He is definitely the favorite, but there is still plenty of games left. I'd say Bradford, and Sanchez are still very much in the race, along with possibly Tebow if he has a good run the rest of the year and Florida wins out. Also, you could make a case for Harrell as long as his team keeps winning. I think they lose at least 3 times, but if they go undefeated I think he would have to win it.
I think he is up big time right now, but I just can't call a bet like that an easy winner with so much time left. All it takes is one hit to his knee and there goes the Heisman.
