Joe Posnanski argues for Chase Daniel for Heisman here. This is a great quote that sums up the popularity contest that is the Heisman:
The larger point is this: If the situations were reversed — if it was Tebow with the excellent stats and leadership for No. 1 Florida and Daniel with the eye-catching touchdown numbers on a three-loss Missouri team — you know the Heisman criteria would suddenly be different. You know all the talk would be about Tebow’s intangibles, his ability to run the offense, his value. Nobody would even be talking about Daniel.
Joe has nothing bad to say about Tebow. He's a great player and seems to be a great kid. But his issue is with the voters.
