I've said the same thing about many previous Florida QBs who were touted as being fantastic (eg. Grossman) when in fact the Florida offensive machine was such that any mediocre QB would look great in it. Tebow, however, is different. VERY different. He is the kind of talent that comes along once every ten years or so, and he may be even rarer than that. When he started the year his first instinct was to run. Over the season he has turned into an excellent passer. He's a freakish talent with the brainpower to be an outstanding mental QB, as well.
He is incredibly special, and if he doesn't win the Heisman it will be because he's a sophomore and the voters will think he can win it as a junior or senior, thus leaving it open this year for someone else.
All that said, the Heisman is the penultimate manifestation of herd thinking and is often nothing more than a popularity contest.
