The one thing the Big 12 cares about is money. The reason they have resisted expanding so far is because there aren't teams available that make a 12 way split as lucrative as a 10 way split.
The Big 12 doesn't need to add teams to improve recruiting, and it doesn't need to add teams to improve the quality of football. It may need to add teams so that it can have a playoff. If that is the case then UConn is in play. We may add more revenue than any other available candidate.
Nothing surprises me when it come to CR, and Memphis and Cincy may well be the choices, but UConn has to be a strong candidate; and I suspect that a lot of the recent buzz about UConn is because people are figuring that out.
The Big 1o decided that they wanted to be more than just a midwest conference, so they came east, let's hope that the Big 12 is just as smart.
