"While we are more likely to move off money and adjust to betting trends with something like the Heisman because of the subjectivity of it all and how it is not as mathematical as some of the other props we offer, that said, to move a Heisman candidate this much in two days is very unusual."NCAA 2014-2015 Season - Odds to win the Heisman Trophy (Players in red have longer odds, players in blue have shorter odds, and players in black stayed the same)
Odds on 9/2/14 Odds on 9/9/14 Current Odds
