He was always looking to hog the university's resources for himself (most of the time) or the football team (some times).
The national championship volleyball team, for example, was the target of his demands, and he pissed off a lot of people when he tried to get their resources pulled, even demanding that the training table for the ladies be shut down.
There were plenty of resources to go around, but he was on a big time power grab, and he found out that he wasn't nearly as powerful as he thought he was.
Heck, even Trev Alberts, his old teammate, chopped his salary, and gave him a "win or else" ultimatum.
All of the above, though, pales in comparison to his behavior outside of athletics. I'm pretty sure he's still banned from many of the bars in the city, since he was basically trying to be Johnny Manziel while being in his 40's.
