They got it right with invitations:
1. Toby Gerhart (1736 rushing, 149 receiving, 5.6 YPCarry, 26 total td's- all rushing)
2. Mark Ingram (1542 rushing , 322 receiving, 6.2 YPCarry, 18 total td's- 15 rushing)
3. Ndamukong Suh (82 tackles, 12 sacks, 1 int...Oh and all while being double teamed)
4. Colt McCoy (3512 Passing, 348 rushing, 70.5%, 27 td's passing, 3 rushing)
5. Tim Tebow (2413 Passing, 859 rushing, 65.2%, 18 td's passing, 13 rushing)

Just missed out:
C.J Spiller

and yes that would be the order from most deserving to least, according to the Heisman Mission Statement which is by no stretch a clear cut definition...(you would be hard pressed to find any wording that might restrict personal guidelines from coming into play)

“The Heisman Memorial Trophy annually recognizes the outstanding college football player whose performance best exhibits the pursuit of excellence with integrity. Winners epitomize great ability combined with diligence, perseverance, and hard work. The Heisman trophy ensure….”

How do you determine that! I mean Toby looks like the least naturally gifted athlete so does that mean that he had the best pursuit of excellence?(with integrity of course) Tebow, at least by what the media loves to portray, is 70 years away from canonization; So did he show the greatest integrity this year while pursuing excellence? hmm. And no one epitomized great ability combined with diligence, perseverance, and hard work better then Ndamukong Suh who had the pleasure of getting his stats ALL while being double teamed! (680 pounds vs 295 sounds like hard work to me!)... and then comes the ever so overrated and unfair "exposure" factor: I looked through the whole website and no where did it say anything about 1. Team wins 2. Viewers 3. That ooh ah appeal?! 4. Must have touches on the ball (D-linemen?)...So why do those four variables constantly receive the highest BETA weights (yeah I just pulled out regression analysis). All I know is that as long as there is ambiguity as to what exactly a Heisman Winner is, then subjectivity and uncertainty will continue to cloud these results...So after the voters cast their votes this coming week, we might not end up applauding the most deserving candidate... but simply the popular prom king of college football.
