You guys are just ridiculous sometimes...
1. Callahan did not suck the life out of the program. As an example, do you not remember the 80,000+ trick plays we ran against Colorado last year?
2. What circumstances are you talking about? Oh, do you mean the NFL-adopted west coast offense? That one that would put a quarterback in one of the best positions he could possibly hope for if planning on making it to the NFL? Tough circumstances... The only circumstances Keller had to cope with were being put into a pro style system when he was not that kind of quarterback, but even that is a good thing, because for whatever team picks him up, he's already got some experience.
