If Texas and Oklahoma do move to the SEC, it could be the end of the ACC as a major conference ($$$ wise) even if ND were to sign on as a full conference member. The ACC has been paying out $10 million per school less than the SEC and $20 million less per school less than the Big 10 even with the ACC Network being added.
Do you really think the addition of ND alone with a WVU, Cincy, or Houston to get to 16 members would position the ACC to get the same TV dollars as the SEC with Texas and Oklahoma as well as the Big 10 with perhaps the addition of Kansas basketball and Iowa State or Oklahoma State?
My fear is ND would tell the ACC to ***** off and join the Big 10 for the big bucks. I know there is a first rights agreement with ND should they decide to join a conference with the ACC, but if ND wants into the Big 10 everything is negotiable. The only conference realignment that I can remember that fell through was Texas, Oklahoma, etc. to the PAC 12. Other than that, anyone who wanted to go elsewhere has been able to do it.
If I were the ACC commissioner, I'd get an estimate as to what TV package would be available if the ACC were to add ND, Texas, and Oklahoma. I would think it would definitely get the ACC into the tier of the SEC and Big 10. Then, bring it to ND, Texas, and Oklahoma and see if something could be worked out. A football conference with Clemson, ND, Texas, Oklahoma, FSU, and Miami would have the brand recognition to go up against the brand recognition that the Big 10 and SEC currently possess. You'd be looking at a 18 team conference with a WVU or Houston added as filler. Gotta think big people as Texas and Oklahoma have made it known they are free agents now.
