It is crazy to me how these things change over time. Given today's standards guys like Colt Brennen, Timmy Chang and Case Keenum should have won the Heisman running away. To me, Lawrence may be the most prototypical but you have to grade him on the same curve you would someone coming out of Boise State or BYU. The competition just isn't there. Mac and Trask are very similar both in story and in stats with one glaring exception, TD's.
But, UF has 6 total rushing TD's on the season, Alabama has 24. Heck, if you take away Harris's, Bama would still have a 7-6 advantage.
I think it is Trask's to lose though, seems like the voters get less and less into nuance and more and more into what shows up on the highlight reel on sportscenter.
