USC quarterback John David Booty, left, is the frontrunner to win the Heisman, according to odds listed on the site Bodog.

Three of the past five Heismans have gone to players from USC, including quarterbacks Carson Palmer in 2002 and Matt Leinart in 2004. Reggie Bush won the award in 2005.

Chris Huston, who runs the site Heisman Pundit, outlined several reasons why Booty was considered the frontrunner when he was a guest on the radio show last weekend. You can listen to that interview by clicking here.

Huston also mentioned several darkhorse candidates, including Nebraska quarterback Sam Keller, who was not singled out on Bodog’s list. Keller falls under field (all other players) and his chances are 7-1.

Unlike Booty, Keller’s campaign is unique. His chances are not as strongly tied to Nebraska’s record, much like Booty’s are to USC, and he will have the opportunity to put up monster games against some questionable secondaries in the Big 12.
