I say we drop Northwestern and let them go to the MAC. For additions, I would consider Louisville, Nebraska, Mizzou, West Virginia, just off the top of my head. Those are the toughest teams immediately outside the Big 10 region that I can think of, and Mizzou and Nebraska are even reaches geographically. After that, our closest neighbors are pretty soft. We would have to travel through a couple of campuses to get to the meatier teams in any direction. I hate Notre Lame too much to consider them, and they would have to scrap some long-standing rivalries to join any conference right now. But it would be nice to beat up on the Hamburlgar's domers every year for a change.
