The way some of those negotiation points go, especially the stuff that kind of gives JHU an out at any time, leads me to believe it's more likely the ACC or B1G, who might jam them up with exit fees and other junk.

Still, I don't think it rules out any of the conferences who were rumored to approach them: ECAC, Big East, CAA, or the Patriot...

Or, maybe the Ivy?

Not the Ivy. They don't need another team.
