Bush doesn't have the numbers for the heisman. Maybe in a year or 2.
Both White and Leinhart have similar stats. Voters will remember Leinhart's performance against UCLA, but they will also remember White's performance against LSU.
I don't think Peterson will get it because he's a freshman, and because he said he thinks White should get it.
Between White and Leinhart, I really don't know. White will have won it 2 years in a row, but the other option is to have a USC quarterback win it 2 out of 3 years.
I think the more interesting question is who the last finalist? Alex Smith has been having a great year for Utah. Both JJ Arrington and Aaron Rodgers at Cal have had very good seasons. And, there's always Cedric Benson.
