Malzahn does a lot of things to put the defense in conflict and causes them to think and make mistakes. He runs a lot of unorthodox formations, motions, and the QB is a potential ballcarrier. I just watched the first two series of the 2013 Iron Bowl. Every Bama run was a direct handoff to Yeldon. Aside from play action, no chance it was anything else. It's kind of like "We are running right directly at you and if we can't physically push you out of the way and/or run over you, this play has no chance." However, on Marshall's early TD run any of three AU players could have had the ball. The WR in motion, the RB, or the QB. The WR brought the OLB upfield and the RB caused the ILB to take false steps. This opened the door for Marshall's TD run. Great misdirection. Didn't have to manhandle either one of those defenders. The scheme took them out of the play. That is great coaching.
I was a little critical of Saban in another thread, and this is one of the reasons why. I don't think what Bama does on offense would have much of a chance with inferior talent. Malzahn, on the other hand, seems to do more things that can be effective without stud players.
If I had to pick a coach to create the Roman Empire out of an elite program, I would pick Saban. But if I had to pick a coach to overachieve with a ragtag unit, I think I would take Malzahn.
That's my opinion.
