Well that's the thing, almost everyone is a system QB now. Tim Tebow almost never takes a snap under center and Urban Meyer runs a gadget offense full of tight end shovel pass options and read option reverses. I would argue that offense is more of a system and less based on individual QB talent than the spread that Houston runs. Also Bradford ran the spread last year and was able to put up ridiculous numbers and win. There are very few "pro style" offenses left in college football, some notable teams that utilize it however would be USC, Notre Dame and Nebraska. This is why Jimmy's numbers are even more impressive, while he has a good supporting cast, his numbers aren't inflated against repeated FCS teams or a spread offense system. The numbers he's putting up in the system, now while hurt and without his best receiver are incredibly impressive. Ultimately it's definitely possible for a system QB to win, they have the past 2 years, it's just a matter of the opponents they play, which Keenum can't change.
