The B1G does not have a contiguous state requirement for expansion, so - in theory - they could easily take both Oklahoma/Texas without worrying about also grabbing Kansas in order to connect their states. I do agree with Stever that the next SEC TV deal will sky rocket (at least its most likely), but I do think the academic association for state universities (especially of AAU status) is a huge value in itself. I do not think that Texas would move to the B1G without another Texas-affiliated school to come along with it; and I am unsure if the B1G would take-on that demand in order to get Texas. I think Texas, long-term, is a much easier fit (if they ever were to move) for the SEC, as A&M is already present (I know the schools aren't jumping at the chance to realign currently, but that could change in the future) as well as bringing along a TCU (which would solidify the Dallas market).

For the B1G, long-term, it might very well be easier to push west and begin a raid on the PAC with Colorado. Denver is a huge market for B1G alumni, and it has been rumored that CU has been underwhelmed (like a few) with the PAC Network. I still think an Oklahoma/Kansas pairing is most likely (if there is a Big 12 raid) for the B1G (w/ Colorado and Iowa State likely if they move to 18), with Texas/OK State going to the SEC (w/ TCU and WVU likely if they move to 18).
