I don't think people are "glad" he lost his scholarship. He reaped what he sowed. He wanted to get hammered at the game and run onto the field. It was selfish and totally unacceptable behavior. 106k+ fans, many of which who were hammered, managed to watch the game without running onto the field. It's not normal or acceptable behavior to run onto the field- it is completely inappropriate, illegal, totally selfish and completely self-absorbed. You know how many students who graduate with debt would kill for the opportunity he had, to attend school completely free of cost? He had that opportunity and this is what he did with it.
As a fan it pisses me off that someone would run onto the field and disrespect both teams, the university, and themselves. It's just embarrassing. It's also not his first run-in with this: he bragged on twitter and had photos of him on the court at Madison Square Garden.
