After the Big Ten takes Stanford, UCLa, USC, Oregon, Washington, and ASU, Big 12 could gobble up Colorado, Arizona, California, and Utah though. THAT wouldn't be a nice division down the road:
WEST: BYU, Arizona, California, Utah
SOUTH: Texas, Tech, Oklahoma, OSU
EAST: WVU, Cincinnati, TCU, Baylor
NORTH: Kansas, KSU, Iowa St., Colorado
