It's not a question of watching the soccer team. It's a question of putting her in the best position to succeed, and apparently Schiano and his family think that is best done by not moving. He's got plenty of money, and he can afford to follow his preferences.
BTW, while several in this thread insist that Schiano wants to come back here, I really don't see any reason why he would want to. He would have to do the same job he did before: make the team respectable. What glory is there in doing that again? Maybe he thinks he can make Rutgers a consistent top 20 team, but that will be hard to accomplish now that we have a tougher schedule than in Schiano's first reign. Yes, there were good teams in the Big East, but he didn't have to contend with Ohio State, Michigan and Penn State every year. And I'm sure Schiano is very well aware of all of the barriers here to constructing a top 20 team.
