Honestly, this never even occurred to me, but it seems like a possibility. MVictors put the idea into my head, and now I can't get it out.
At least it splits up OSU and PSU. We already know that Iowa and Wisconsin are split, so the only question is whether Iowa should be in Nebraska's division, or not. I'll guess they will be:
- Michigan, PSU, MSU, Wisconsin, Minnesota, Northwestern
- OSU, Nebraska, Iowa, Purdue, Indiana, Illinois
For what it's worth, I could live with this if M versus OSU must absolutely be broken up for some reason I can't see.
