I don't feel the Big12 should add anymore Texas programs- we already have Baylor, TT and TCU. Any Texas school added would be the 6th best school in Texas.
Look at other conferences and it is unusual for a conference to have more than 2 teams from the same state. ACC has 4 NC schools and Pac12 has 4 CA schools. In both cases, 2 of the schools are the premier state schools
If the Big12 expands, it needs to expand its footprint. Expand the Big12 brand, not focus it. I am torn because it would seem BYU & Cincy are the obvious choices. But IMO the Big12 would be better off to go east or west. I guess they could do both if they expanded to 12 or 14.
Don’t really think a per-state limit is a good way to approach things. If Houston is the best TV money and competitive option then let’s do it. Bonus points for being a great recruiting metro.
