It’s as simple as this. The situation that JH came into is not the same as what every other HC walks into. What he faces right now is absolutely unprecedented in our football history.
All true... and meaningless with regard to how much time UT can afford to give him. If he doesn't do something to prove himself a great coach within the first 3 years then recruits won't listen... and they do not CARE what his situation was.
There are a number of things that could establish him. Getting a couple or 3 wins against UT's "big" SEC opponents in the first 3 years would definitely qualify. Re-establishing dominance over UK, Vandy, Mizzou, and USCe would be a big step that could be sold to recruits. There are a number of ways he can earn credibility.
The thing he cannot do is have a losing season or appear to be treading water or backsliding.
In short... he has to have something to "sell" that's tangible.
A championship caliber coach? For crying out loud man are you insane? Are you one of these deluded fans that thinks oh we are TN and we should expect championships?
Are you one of the deluded fans that think championships are won by luck? High expectations are a foundation for great results. That's pretty much universal and nowhere more true than in a college football program. If the fans accept a low target... the program will undoubtedly hit is consistently.
If all new HC jobs were equal in difficulty, then your point would stand. They aren’t. So you can stammer on all you want about oh if he isn’t any good by year 3 then he has to go. But it’s a dumb way to think.
No stammering. History across top end college football programs.
But the "dumb" way to think is that "fairness" or starting difficulty have anything to do with it. I'll agree that it isn't "fair" that Heupel walks into a mess and will have to perform at an amazingly high level to survive. That doesn't change the reality of what happens if you keep a mediocre or worse coach past 3 or 4 years. If a guy isn't a good coach then more time won't make him a "better" coach fast enough to make up for the dearth in talent created by his on the field failure.
