You simply cannot fire a coach for cause with NCAA violations and fire the AD who wanted him and then turn around and hire a guy who was fired for the same thing. It's not happening. That's thing number 1.
Number 2, even if UT offered him the job, with possible big sanctions coming, he's not going to want the job. He will go somewhere where he can have success immediately.
Look for a very safe, unexciting hire. Not a no-name hire like in years past, but not someone who excites you.
Also, the next coach at UT will not be the one to lead UT back to a championship. It will be the one after him.
