It might be happening, and soon. Chatter has picked up after the most recent last straw. Today I've gotten two reports that Brandon is resigning in… a couple hours(!). One comes second-hand from within the department, the other second-hand from the regents*. Premium sites seem to have the same chatter.
Prior to what seems like a major shift today but after the most recent last straw I had heard that the next bye week (ie, after Northwestern) was a point at which something might happen, with another independent report from within the department asserting that knives were being sharpened, and a report from one of the events being held in the run up to the regents' election that he was done in a couple weeks.
The the emails supposedly blunted a lot of pushback Brandon's supporters were trying to muster. While you should keep in mind that someone who would relate this to me might be inclined to believe such a thing, John Borton is… uh… not so inclined, and he asserted that white flags are being waved($) inside the department. Sorry if that sounds like self-tootin'. Nobody likes a self-tooter.
*[Note: I endorsed Mike Behm. I should clarify that none of this comes from him or his camp.]
I am told by several sources there will be a 1:30 press conference at UM involving the president to discuss AD Dave Brandon
