The ACC would be the PAC 12 right now if not for the long grant of rights. That would probably be better for FSU, Clemson, and anyone else making it into the SEC or Big 10. But the GoR is doing exactly what it was meant to do: keep the ACC together.
And we're not locked in, there's an out built into it.
If the ACC schools really want to stay together and everyone is just upset about not being able to negotiate a new rate, there's nothing stopping us from dissolving the GoR and negotiating a new, higher dollar contract. It's not happening because as soon as that happens schools will bolt and the conference will die.
