The problem I see with the consensus choices Lakes and Heartland or Lakes and Plains is Michigan and Michigan State aren't Heartland or Plains and Ohio and Purdue aren't exactly Lakes region either. If you're going to break it down at all you can't designate regions because the Big 10 threw that out the window as soon as they put the two Michigans in the western division and Wisky and Illinois in the eastern one. X and O make about as much sense as anything.
