re: If Johnny Manziel doesn't win another Heisman, is it out of spite?

I believe the answer has already been mentioned. He will not win it twice simply because of the off-the -field stuff. Turns out showing your arse in public disrespects the honor associated with the trophy along with all the previous winners who chose not to show their arse. They chose to embrace something larger than themselves, which JFF is incapable of doing.
Maybe not so much because of disrespect, but imaturity or intelligence maybe, IDK. Personally I think he's still the best player in CFB. Manziel to Evans is a force.
