Playbook variance is not such a big deal in the pros; although you have the West Coast, the Erhardt-Perkins, the Coryell, the traditional I-formation, etc., the devil is in the details. There are very few teams that are truly "out there" in comparison to the competition. It's mostly about talent, execution and playcalling acumen.
But when you guys decide to turn out the college game, that's when this is going to get choppy. You have all the NFL offenses, plus the spread-option, flex-option, flexbone, wishbone, triple option, HUNH, run-and-shoot, pure spread, single wing, double wing, wing-T, and if you're going for the historical as well, the Notre Dame box plus a couple of others. Moreover, the amount of crossover between a college team running an Erhardt-Perkins derivative (i.e., Alabama) and a team running the Rodriguez/Meyer spread-option (i.e., Ohio State) is virtually nil. Then you have to account for wildcat packages, etc.
Just get ready, the college game is going to seriously keep you guys up at night.
