They talked about this on 104.5 the zone in Nashville. The main thing this guy hangs his hat on in his article is that Pruitt talked about GPAs instead of winning or fixing this or that. He actually talked about many things, including fixing this and that. He has talked about the weaknesses of the program since he got there (guys too small, not tough enough, etc.)
I think Pruitt knows what the Vols weaknesses are. The question is can he fix them, which brings up another question, will he be given enough time to fix them?
Coordinators become HCs all the time. So the fact TN hired a Coordinator is irrelevant. Also Pruitt's salary is not too over the top for SEC HCs from what I have read. So basically all sub par points on the authors part, IMO.
Will TN ever be elite again? I don't know, but I do know that they have the facilities, money, etc. to get there. It will really depend on who is running the show. Is Pruitt the guy? Only time will tell.
