Maryland was the only ACC team willing to risk having to eat the $50 ACC exit fee. If Maryland can negotiate it down to $20 million or so, it sets a precedent and the ACC is done. I predict the Big 10 goes to 18 with Georgia Tech, Virginia, North Carolina, and Duke, and the SEC to 16 with NC State and Virginia Tech. Of course, the SEC would prefer UNC to NC State, so it could end up being Syracuse or BC to the Big 10 instead.
The remaining good ACC programs (Clemson, Florida State, Miami, Pittsburgh) will wind up in the Big 12, while Wake Forest and the other dregs may end up in the "Big East", which is essentially a rebranded CUSA now.
