I've heard some speculation that if OU leaves the Big 12 to a conference that Texas doesn't join, that Texas will stop playing OU as "payback". Very interesting. Supposedly UT/TAMU is off the table if TAMU leaves for the SEC. But there is a huge dynamic at work with the OU/UT game that some folks might be overlooking. That is that the OU/Texas game brings in millions in revenue for the state of Texas every year. Assume that each OU fan who travels from Oklahoma to the game, and I'm going with a low estimate of 30,000, spends only $500 each at the Texas State Fair and hotels/gas stations in the area. Even with that estimate that is $15,000,000 flowing into the state's coffers for the game. And every single year that cash flows in only one direction. And I think we all realize my estimate is lowballing it to a high degree. I wouldn't be surprised if the actual figure was $30,000,000 or higher.
It's my contention that even if UT itself wants to drop OU from the schedule, that there is no way that it could politically be accomplished. Frankly I'm amazed that the politicians in OKC don't demand that the game go to a home/away system so that Oklahoma doesn't bleed millions in revenue to Texas every year, but the politicians in Oklahoma have never been reknowned for their brains (or common sense, or incorruptability, lol).
