I'm not sure if it was lack of vision or Texas blocking things to preserve options (among other things), but if the Big XII had picked up UL, Pitt, Cincy and WVU, they could have had a shot at luring Miami, FSU, and Clemson. At that point adding Memphis is a reasonable fit when you look at culture, proximity and beefing up basketball. Back out TCU and you have had a decent East/West divisions (or leave in TCU, nix Memphis, and send Iowa State East).
EAST Pitt, Cincinnati, Louisville, WVU, Memphis, Clemson, FSU, Miami
WEST Iowa State, Kansas, Kansas State, Oklahoma, Oklahoma State, Texas, Texas Tech, Baylor
WVU and TCU were football-driven picks and not market driven picks. Maybe the model is changing for them, or not. I guess it's better being mentioned than not being mentioned.
