He's pretty stubborn about his air raid though. Several of his proteges have added more gadgets to the base offense to make it harder to defend. Holgerson, for example, has more motions and a bit more run plays built into his version of it.
This year when UDub beat Wazzu yet again, easily shutting down their offense, it was kinda slipped by the UDub staff that they're able to do this because they've figured out how to defend his base plays and constraint plays yet he won't adapt.
Saban and the defensive staff need to get all the tape for the last ~6 years of UDub D v. Wazzu and figure out what Jimmy Lake was doing. I'm betting on Leach to basically run most of the same stuff Joe Kines had to deal with in 2005 when we play this Fall.
