The BigXII stays intact unless the bottom tier BigXII schools can find an equitable landing spot. ESPN/FOX made the BigXII work by overpaying for content. ESPN/FOX can also make dissolution work if it's in their interest. If ESPN ever found that it could make more money from the ACC network by expanding the network footprint with the likes of Baylor, TTU, OkSU, KSU, ISU then it would be game over for the BigXII. Deregulation of the CCG/Divisional Round Robin Requirement (ACC and BigXII driven) would completely open the door to this kind of ACC expansion.
