Last year the knock on Quinn is that he never won a big game. Tebow had three big games this year, losing all three (Auburn, Ga, LSU). In none of those games did a fearless Tebow lead his team from behind to score even one TD. In fact, in reviewing the UF boxscores, Tebow very rarely led his team to score in the last minute of the half or of the game. His only late first half drive in a game that wasn't a blowout already was Kentucky (if I'm not mistaken). BQ during his last two seasons had multiple drives to close out halves, and to close out games. Remember, the only reason we didn't beat USC in '05 was because BQ was TOO efficient and scored TOO quickly, (I believe he took less than a minute to drive the length of the field), as opposed to the "heroics" of Vince Young, who took much longer to score (and even then almost leaving too much time on the clock!).
Tebow hasn't done much in the clutch, hasn't won a big game, and has played one season.
Give him the Heisman. Hell, give him three.
