Depends what we refer to by pressure.
In terms of losing their job, Sumlin is at the top of the list because of the QB transfers and other mess (how the mighty have fallen).
In terms of faith in a coach and where they will take the program......and you all can deny it all you want......if on 9/24 Tennessee loses to Florida......again.....mattresses will burn. People will declare Butch a great guy, but not the man to take Tennessee where they eventually want to go.
Now, I can already see the replies "what if we go 11-1" yada, yada, yada. If Tennessee loses to Florida, they aren't going 11-1.
But, I am convinced that if Tennessee does not win the East this year, this fan base will lose all faith in his ability to get it done. They will credit him for bringing the program back to respectability, increasing the level of talent, making Tennessee relevant again, etc. But, they will also conclude that if they want a championship, they are going to need another guy.
JMO.
So, yeah, Butch is under a different kind of pressure. But, he ain't losing his job. He's not losing his job with a 7-5 season.
