People are making a lot out of Motta's poor showing. Maybe he got hurt, maybe he has a motivation problem or maybe he was not properly prepared.
Eifert was better than expected, Wood about as expected, T'eo a bit below expectations, Riddick got hurt and Motta well below expectations. That isn't much in the way of a data set.
We got beat by Alabama about every way you can get beat. They had a decided physical advantage on us, our staff got out-coached and two key members of the defense (at least) played the worst games I've seen them play.
You can have the greatest strength coach in the world, and if the players don't put in the extra effort it won't matter. He can't do the lifting for them.
I do think the formal training table has helped things. We didn't have the late season nosedive that we saw, particularly under Weis.
It ultimately comes down to Kelly. Presumably he understands that having a physical advantage over as many opponents as possible will make his job easier.
