If you think adding TCU and WVU is the same as having Nebraska, Colorado, Texas A&M, and Mizzou then I feel sorry for you. The last 10 years is the last 10 years. Go look at the historical #s between all the programs you just lost plus add in the market value, fan bases, and tv sets they lost with all this re-alignment. The big12 is most certainly not better off and there isn't even an argument. Then start thinking about all the other sports, academics, stadiums and things that are important to a conference.
lol TCU having a good 10 years. The last time they were relevant at all was like the 1950s before this run they had going shuffling between the power house conferences of the MWC, WAC, and CUSA.
West Virginia has a good historical football program, no doubt about that, but it still doesn't make up for what's lost.
