It's pretty simple, I think.
He has to challenge for the East. Serious challenge, one that either we win, or remains close right up to the last game or two of the season.
I don't know if that translates into 9 wins, or 8, or 10, but that's what it will take.
This season was--or would have been, in a normal year--a 6-6 result. Add three cupcakes, take away one harder game, and you have a "normal" schedule, a schedule just like every team in the SEC plays, every year. So, 6-6.
Which is not as horrific as some of you portray, with all the hair you're pulling out and gnashing of teeth you're enjoying. Don't get me wrong, 6-6 is certainly not good. It is _not_ where we should be in Year 3. He failed, this season. Specifically, he lost to Kentucky and Arkansas, two games he absolutely should not have lost. He stuck with JG too long. He didn't have the offensive line as developed as their collective natural talent indicated they should be. The receivers weren't getting open. The defensive backs were spotty at coverage, both man-on-man and zone. All parts of the team made dumb mistakes far too often, resulting in both penalties and turnovers.
So sure, we should've been much farther along in Year 3 than we were. But it still wasn't as bad as some here are making out. It wasn't "the worst season ever." It wasn't close to that. It wasn't nearly as bad as Butch's last season (remember: we did have 3 cupcake games that year, and still went 4-8...Under coronavirus conditions, that would've been a 1-9 year).
So, all that said, Pruitt's in a dog house. Yes, with Phillip Fulmer. Who loves Tennessee a helluva lot more than he likes Pruitt, though I do think he likes him just fine. Who, I believe (though I could be wrong here) actually loves Tennessee even more than he loves his own well-being. And would sacrifice himself for the program, if it came to that.
So I don't think Fulmer would have any trouble firing Pruitt & Co. if we don't see success in Year 4.
And the undeniable definition of Success in year 4 of a proud program with our lineage is being back. Back to challenging for championships.
Nothing less will do.
