Just saw someone retweeted a Mullen tweet and it says, "Spending time w/ @coachjim4um and the Michigan football coaches today brought back some good memories" and he had included a picture of the Gator Bowl trophy in a case w/ a sign above it that had the score on it. I wouldn't have thought anything about it if he hadn't tagged Harbaugh in the tweet and included the picture. Another SEC coach firing a shot across the bow?
