Pruit grew up in football and has worked for some great coaches. It's in his blood. He has moved around a lot, though, and doesn't seem to stay in one place very long.
He seems to have some decent basic principles about discipline, leadership, teaching, practice, and recruiting. But he doesn't seem to have developed much of an overall vision and philosophy that puts all that together, and may not be as flexible or able to adapt to circumstances. Maybe that will come with experience.
Mostly, He dosen't seem to have the personality, style, vocabulary, intelligence, management skills, polish or charisma to be CEO of a multi-million dollar operation with lots of moving parts. He was plucked out of middle-management ranks and thrust into the spotlight. He inherited a mess, possibly before he was ready or able to clean it up..
Of course it was a great opportunity for him and of course he jumped on it. It's possible he's having regrets. He may have been in denial about the enormity of the task, and may now be starting to realize he isn't experienced enough and maybe not even cut out for the job. Fulmer can help him grow into it if Pruitt will let him and if he can put aside any stubborn pride. We can only hope it's not another example of the Peter Principle in action.
