Well it definitely isn't over yet, with Maryland and Rutgers going from the ACC and Big East respectively to the Big 10. With Notre Dame coming in part time for football the ACC made a big exit fee, yet it didn't deter Maryland from leaving.
Don't forget Pitt and Syracuse are coming to the ACC so they'll be ok, but the Big East, especially now with Boise looking to possibly go back to the MWC, things are picking up again
