The ACC's number one motive is money. They want to make it a powerhouse football confrence, and an even better basketball one, only to generate more revenue. I suppose they arent happy with an explosive Duke vs MD, UNC vs Duke B-ball rivarly, and a football confrence with an elite FSU team and excellent squads at NC State and Maryland. Its all about making the rich richer, Karl Marx is spinning in his grave
I do not know the legality of the situation, but from a fan's (ACC fan nonetheless) perspective I think the ACC is being greedy, and the Big East is getting dealt a joker.
