The "pressure" at USF is not compatible to the pressure at UT.
At UT, the boosters OWN the program and demand tons of off-the-field junk from their coaches. They also have the (no longer realistic?) belief that they should be a top 5 program every year. At UT you are a failure as a coach unless you win 10 games every year and bow down to rich morons is cowboy boots weekly. Then, on top of the crazy expectations and boosters, you have to deal with the school owning its own TV network. It's a horrible job (but the money is great).
At USF, all you need to do is win some games and smile for the cameras.
