Yeah, I didn't think accreditation would be their problem. Administratively, UMass knows what they're doing. More along the lines of SNESL's not so great legacy and the reception in the area.
The school is right, its silly for a state the size of Mass not to have a state school, but the legal market in Mass is crazy competitive. Will their market be RI or CT? Or will grads filter into Boston, where there are too many law schools already? The south coast isn't populous enough to support a law school.
