From Shaggy...
I'm working on a more in-depth story, but the reason Texas is tapping the brakes on any frenzy about other school additions (Fla St, Clemson, etc) is because DeLoss Dodds is convinced Notre Dame is moving to the Big 12. Initially, it was ND's non-football sports. But now, there could be some formula built into the Big 12 that would allow ND to function - at least in the short term - with its NBC contract in tact before being phased into the Big 12 as a whole football member.
DeLoss, I'm told, wants that ironed out before anything else gets ironed out. It's complicated. But it's fascinating.
The top priority is Notre Dame (at least in Texas' eyes) and then everything else.
I know that one other factor necessary for ND's consideration is that they want a minimum of 4 OCC games, and 5 would be better. That requires a small conference (12, 5division games & 2-3 cross division games) or a pod system with 16( which has NEVER been successfully done long term before). This is a major limiting factor, and will require some compromise probably on both sides parts. The 16 might be easier, but is way riskier. Adding some of ND's traditional rivals might be part of the process. GT and Miami would be the obvious ones, and I'm not sure where Miami's administrative head is at. They are about to get slammed hard by the NCAA. Their administration is talking about reducing their athletic funding and emphasis. And their relevant historical financial data (attendance, etc.) is trending downward so that they won't be able to keep up in facilities or top level coaches, becoming only a coaching stop rather than a destination. Their current status is no worse than some of our current members, except their infractions record is way worse, and the trends are equally bad, and then the forthcoming penalties. That's a lot of negatives to overcome, and a lot for the B12 to swallow. They would ONLY be invited as part of a ND package, & ND would have to sign first.
Not sure what other items would have to be worked out, or who else would be attractive or tolerable to both ND & the B12. NCAA might have to change rules to allow 16 teams on a pod system with rotating divisions for the championship, not sure.
