Just depends ...
Dak is slated 33-1 odds per Vegas' last update. Can he win the Heisman in 2014?
But looking at it 'right now' ... he has a realistic chance to compete and who knows? There is only ONE winner, so those odds ought to be much worse. If I was near Vegas before the season starts ... would definitely take a shot.
It depends on factors like ...
+ Got to STAY healthy
+ Having a 'good year' goes without saying ... having more experience at WR, TE will help, plus RBs that can catch and can get in space can help
+ Inrease passing % is a must; ability to gain yards when pressured aka JFF helps, also; dual threat gives him another advantage
+ Team doesn't have to win the NC (but, it DOES help ... see '13) but has to have a GOOD year and beat some GOOD teams ... A&M, Auburn
+ Keeping any loss close doesn't hurt
+ Display both the leadership and QB maturity he showed in the 4th quarter of Egg Bowl and Rice game
Besides raw talent, Dak has that innate abilty to gather, focus and lead his team and the rest look up to him.
