Don't get me wrong. I absolutely think Saban is a great coach. But his greatness is 80% the players he recruits and 20% the coaching after.
BYU just doesn't have a stable of horses like Alabama. Of our starting 22...maybe 3-4 could ever start at Bama. Maybe. Saban demonstrates what happens when great athletes get great coaching. Mack Brown demonstrates what happens when they don't.
Bronco...he's working with an entirely different set of circumstances.
