This is Misopogon - I'm leaving this board post up in case anyone comes hearing a rumor about Michigan defensive coordinator Greg Robinson and a resignation. A rumor was posted on a Rivals board, and a moderator refuted it. At the moment, it seems like someobody made something up, and then someone else with information called it ridiculous. Michigan's defensive coordinator is Greg Robinson, and there is zero information, credible or otherwise, suggesting otherwise. Carry on.
That's it and that's all.
2 separate people have said it, though sourcing is unclear at this point, so it could be false / someone screwing around.. Have to say that I think if he did resign it would be the best move for both parties at this time.
My apologies if I'm just making a bad joke worse, but it is Halloween after all. Mods - feel free to take this down if you've got info to the contrary or think that it is just BS.
UPDATE: One of the guys has now backed off, saying it isn't a done deal. Seems fishy...
UPDATE 2: Now a Mod has refuted. Go back to thinking whatever it was that you were thinking before this happened.
