Look at Luke Kuechly 2011 stats to Te'o 2012 stats and tell me which one should have been nominated for Heisman. Te'o only got national fame because of the death of his grandma and g/f....sorry but true.
The Heisman is more than stats-driven though. Otherwise Mark Ingram shouldn't have won, since Toby Gerhart had better stats. If there's a "Hollywood story" behind a player, that helps too. It is what it is.
