Strategy in College football is secondary. You just need the best athletes most of the time. That's it in a nutshell. It's all recruiting......and it's all very slanted toowards the big guys.
Want proof?
Steve Spurrier, Nick Saban, Pete Carroll, Lou Holtz, Bud Wilkinson, etc.
All good salesmen (great in the livingroom), lousy on the sidelines.
The only exception I can come up with is Jimmy Johnson. (Don't give me Switzer, he was driving Johnson's Lamborghini and screwed up much of the time).
That stuff works in college. Falls flat in the level playing field NFL, where football knowledge and coaching competence is primary.
