They may be able to attempt to frame the AD but are they sure that the reporter who broke the story doesn't have more proof of Urb's awareness of the problem. If the Board throws all their eggs in UM's basket then new info comes out there may be a push to cleanse the Regents seats.
Yeah I'm fine with them trying to blatantly pin this on the AD. Exactly zero people are going to fall for that so if they actually go through with this dumb plan it will be even more of a disaster for them down the road.
