WVU is a solid school, football wise.
TCU got a fortunate boost from Texas politicians. I think they may be trying to rebuild the SWC minus Arkansas.
WVU has a small population, and little to offer in terms of dollars in TV revenue, but they are a good team. I actually wish them well. Their small school need all the dollars they can get and they are hoping to educate a traditionally poor rural populace. That alone is worthy of admiration and I hope they give Texas and OU fits.
I do not think the Bevo 12 lasts long, even with the grant of rights. Last I checked, the Big 12 office signed that TV deal but almost none of the schools have actually signed the GOR. I am guessing that Texas and OU take a few years to let "legal departments review the language." You can bet that the Big 12 will be around as long as Texas wants it to exist, and not a moment longer.
In all this, I say the B1G and SEC win. B1G is not looking good today, but A&M and Mizzou (much as I hate to say it) are solid additions to the SEC.
