Mizzou should be in the Plains division with Wisconsin going Midwest.
I tried to come up with this a few weeks back when I heard about the Super League concept. I wanted to balance it competitively a little more and came up with this:
West: Washington, WSU, Oregon, OSU, Cal, Stnaford, USC, UCLA, AZ, ASU
SW: UT, Aggy, Arky, LSU, TTU, TCU, Baylor, Houston, SMU, Tennessee (not a great fit, but spreads balance)
Plains: Utah, BYU, CU, KU, KSU, Nebraska, ISU, Mizzou, OSU, OU
Midwest: tOSU, Mich, Mich St, Wisconsin, Minnesota, Iowa, Ilinois, NW, Purdue, Indiana
Big East: ND, Penn State, WVU, Cincy, Louisville, Cuse, VA Tech, Pitt, Rutgers, BC
SE: Bama, UGA, Auburn, Vandy, UK, Ole Miss, Miss St, Florida, GA Tech, South Carolina
ACC: FSU, Clemson, UNC, UVA, Duke, Miami, Wake, UCF, NCSU, Maryland
