as others have indicated, there are several poor assumptions.
1- Sarks is ready to coach NOW. what makes you think he will wait two years for the TN Job?
2 - Freeze seems interested in jumping back into Power 5 NOW - again, what makes you think he'll wait around for a TN offer?
Some other school will and these coaches - and others. How many times has TN seen this movie? Other schools move and get what they want, TN fiddles around and screws it up.
3 - How LONG do you honestly think a coach needs to win? To say that Pruitt needs 2 more years...because...he needs to coach up his own recruits...is just nonsense for several reasons. First, he hasn't demonstrated he can't coach the talent that is at TN currently. We have players not developing, and we have very good players not playing up to their abilities. Why is that? Second, he's showing his weakness in recruiting now - players are buying what he's selling.
None of these points hold any water. Pruitt seems to be in over his head.
