If it end's up being him, I would call it a meh type of hire.
For one, when White had to replace Frost at UCF, Heupel wasn't the top choice. IIRC, he was #3 or #4. While that is fairly common, it's important to note since he has backtracked each year while in the job.
Next, all the talk was about how UT was passed Fulmer and they were ready to commit to competing. They were going to spend and spend big. White as AD was a really solid hire and I think that elevated expectations for the coach even more. While some of the names being throw around were long shots (like Franklin), there were much bigger names than Heupel being discussed, though some had character flaws (Lane, Freeze, etc).
Time will tell, but in terms of "winning the press conference", I think this falls a bit short.
Random poll.....which fan base do you think is happier with their hire...Auburn or Tennessee (assuming JH)? I would say Auburn probably feels better, but they also had a head start.
