Cattle (S) & Hat (N), Brains (N) & Brawn (S), named divisions worked SO WELL for the B1G . . . .Pretty similar to yours but I would make it strictly a North/South split:
North: ISU, KSU, KU, CU, WVU, Cincy, BYU, Utah
South: AZ, ASU, Tech, TCU, Baylor, Hou, Ok St, UCF
North would be strong this year but I could see it being balanced long term.
