There are maybe 4 or 5 quarterbacks in the country who could pull that off: Tim Tebow of Florida (mostly because Florida receivers can just flat beat anybody -- they're just too strong and too fast for a Stanford defense -- and Tebow can do enough to help them), Colt McCoy of Texas, Christian Ponder of Florida State, and perhaps a couple others. Only because those guys have done similar work against top-rated defenses in the past and clearly have a nose for winning with time fighting against them.
I wouldn't even trust Alabama, which I think is the best team in the country, to pull it off, because their QB simply doesn't have the air attack needed ('Bama is more of a smash-mouth running team).
Even in that nigh-unfathomable scenario, I might still go for 7. But with a shot at beating a team like Florida, I'd have to at least consider taking the field goal and leaving almost no time left. One important question that would need to be answered: How many timeouts do I and the opposing team have? If the opposing team has none, and I have one or two, that would make me lean that way, because I can then drain the clock without feeling too much pressure on my kicking game.
But again, only given the prospect of beating a high-flying, top-ranked offense whom I know would beat me down the field, and whom I figure I'll undoubtedly lose to in overtime. Conservatives want live babies so they can raise them to be dead soldiers. - George Carlin
