Houston adds noting to the viewing audience for the Big 12 - last time I checked you already had Texas - which you will probably find more Texas fans in Houston than Houston fans (guessing here - but my experience in big cities is that top U in the state has the fans with the local school just sort of oh aint they cute type thing)
Yes there are alot of Texas and Aggie fans in Houston, but there are still alot of Houston Cougar fans down there. Khan did a few years in Houston and I was a frequent visitor. Adding the University of Houston does further sew up that recruiting ground and TV market, and it also adds star power back to the UH name, making it easier for them to recruit and complete.
I honestly still see the Big 12 completely imploding sooner than later. Forget the entire sports angle - Texas is one of the few schools in the nation that could both bring something to the CIC and benefit from being a part of the CIC... which is why I still think somehow they end up in the Big Ten.
The Pac-12 has it worked in their TV deal you cant have your own network, so we cant go there. Going to the SEC doesnt enhance our academics or recruiting, and we were making SEC money before the LHN came along.
I could see the Big 10, but theyd probably have to take Oklahoma too, and find a way around the LHN, not to mention youd **** off Nebraska immensely since they left to get away from us to start with.
