Guess I am going to be the exception here. And, I am only half hearted in thinking this way, but .... here goes.
I miss the Big 12 because the North carried with it the feel of the Big 8 sans Sooners and Cowboys. And Oklahoma was still both an in season possibility and a conference championship game possibility. There is very little chance we see Oklahoma this year. There would have been a fairly decent chance in the old league.
Driveable games are huge. I love me some Manhattan, Lawrence, Ames.
Also not going to be really feeling games against Purdue, Illinois, and Indiana (well, at least in theory on Indiana). The bigger teams Mich, Ohio State, Penn State, Wisky and Mich State have been fun, but the new is worn off already.
Lastly, I wanted to get more shots at the Longhorns. The only way to erase the bad taste of those set backs would be to beat the ever living out of them enough times that Texas fan stops wanting to talk about it anymore.
