I don't think ND to ACC makes sense at all.
Why would they be an exact conference equal with NC State when they could have a Texas type setup or share a bigger pie with less pieces in the Big Ten. It contradicts everything we know about their ego.
It's the fourth most logical place for their football behind Ind, Big Ten and Big 12.
Your statement doesn't make sense. ND said last summer that if they did join a conference because the Big East collapsed, it would be the ACC. Why do you believe that Notre Dame could be the big dog in the Big 10? I doubt that Ohio State and Michigan would roll over and surrender their control of the conference to Notre Dame.
