I'm surprised how many ways there are to gauge the strength of the Big 12 by using Texas Tech as the selected piece of evidence.
I'll never defend Tech. They stink, but I don't see where the bottom-feeder dictates conference strength. Most of the time, you look towards the top of the league, and then note how strong the middle is, and then maybe bother with the bottom feeders.
So for the Big XII you have Kansas, Iowa State, and Oklahoma at the top. In the middle you have West Virginia, Oklahoma State, Baylor, and Texas. At the bottom you have K-State, Texas Tech, and TCU.
I would take any of those middle teams (WVU, Okie State, Baylor, or Texas) and I would pick them to win the Missouri Valley this year.
I'll use the UNI fans tactics to make my case. UNI beat Virginia Tech 73-54 and George Mason 71-65 in OT. West Virginia beat Virginia Tech 82-51 and George Mason 91-65. Clearly West Virginia is better then UNI and would easily win the Missouri Valley title.
Also of note... Iowa State swept West Virginia this season which clearly shows that Iowa State would destroy UNI regardless of where the game was played.
