I don't know....was Hoiberg qualified to coach a Big 12 team when ISU hired him? Gatens actually has more experience coaching than Hoiberg did when ISU hired him. That seemed to work pretty well for them. Not saying it would work in this situation, but it's not like it's not been tried and worked before either.
I think it's also safe to say, TJ Otz, was the man behind the scenes. If Gatens gets an assistant coach or 2 like that, go for it.
