I can see his point that a throwing QB in a spread attack is in some ways more difficult for the secondary to deal with than a running QB. But, its not like, as he suggests, Tebow will only pass 15-20 times. Gators have been doing that this year because they could -- finally had some productive running backs and a stout defense (not to mention special teams).
But if it turns into a track meet, Florida absolutely can throw the ball 40 times. Done it before and can do it again. And that is what makes it harder I think to prepare for Tebow and Florida, which is to say that the Gators can shift gears as the game demands.
Put it this way: If Tebow ends up with less than 20 passes, its because the game was well in hand throughout.
