In all honesty, that probably would be a good place to go for him. McDermott knows how to coach offense and put a lot of points on the board, and they have a good nucleus of players returning.
But rumors on Twitter are that Virginia, Indiana, Ohio St, Michigan, and Mizzou are among the teams that contacted him. It would suck twice as much to lose him to another Big Ten school, but it is what it is. I don't really blame him for leaving, he finished his degree - it's just the timing of it is very unfortunate.
