I can imagine why he'd want to leave. They are in a power conference but they aren't a power team, they are pretty remote from the rest of the conference (they're practically in Idaho), and they don't pay competitively. Also, their athletic department budget is apparently sub-par. That said, I can see why he'd want to stay as well. They gave him (and his father) a shot, he may like the city, he may like the players, etc.
