At this point, it's pretty obvious that some Big 12 schools are in favor of expansion, while others prefer to keep the current 10-team format. At some point - perhaps later this month - the schools' brass are going to put it to a vote and decide, one way or the other. The Big 12 requires 75% of schools to vote in favor to make it happen.
According to Jason Williams of The Cincinnati Enquirer, it is "believed" that seven schools are in favor of adding more schools to the conference, with Texas as the main opposer. Williams also reports that it's "believed" that Texas is trying to convince Texas Tech and TCU to vote against the idea, leaving the league short of the numbers it needs.
Texas Tech has long fallen in line with Texas. Both are public universities that have been in the same league together since 1956, when they were in the Southwest Conference. Texas and Texas Tech were founding members of the Big 12 in 1996.
TCU is believed to be following Texas' lead because the conference's power broker reportedly helped the Horned Frogs get into the Big 12 four years ago.
Williams' article focuses on Cincinnati's viability in the Big 12 - he notes that UC "stacks up favorably" when it comes to enrollment and academics.
If Williams' sources are correct, we could see a huge rift coming between the Big 12's schools. We'll know way more one month from now.
