This may well all be true; the point is that we don't have the luxury of giving him the training he needs to be an HC. We needed to hire a HC (or someone with the right skill set). He doesn't have it. Maybe he'll get it. Why do we have to be the ones to give it? That says a great deal about our hiring process.
Maybe it all works out and the Big 12 reaches down and plucks us out of FCS 2.0 in 5 years.
