At least, that seems incredibly unlikely. Harbaugh starred as a player for the Wolverines and, despite a lack of big-game success, has elevated Michigan’s program back to a level that Rich Rodriguez and Brady Hoke couldn’t. Still, it might be time for both sides to move on.Michigan was embarrassed by Wisconsin at Camp Randall Stadium on Saturday afternoon. The Wolverines entered the season with Big Ten championship and College Football Playoff hopes. Those goals – while still in reach – seem unrealistic.Would Harbaugh get pushed toward an NFL head coaching job (the New York Giants, perhaps?) if Michigan disappoints the rest of the way? That seems possible now.Rutgers head coach Chris AshIf any Big Ten head coach is going to actually get fired this season, it’s going to be Chris Ash, whose Scarlet Knights fell to Boston College on Saturday.NJ.com wrote on Saturday night that Ash could be fired at some point during the regular season.Watch out for some major changes in New Brunswick.Here’s why Chris Ash might get fired before Rutgers’ season even ends | Politi https://t.co/xHmLi3NwP8 pic.twitter.com/JMujaT1mKS— NJ.com (@njdotcom) September 22, 2019Florida State head coach Willie TaggartFlorida State got a much-needed win on Saturday afternoon, but it wasn’t pretty. The Seminoles nearly blew a massive lead, before winning 35-24.Taggart’s Seminoles are now 2-2 on the season and, even with a win on Saturday, haven’t inspired a ton of optimism so far this season.Florida State might not want to move on from Taggart after just two seasons, but unless there’s a big second half of the season rally, the Seminoles could be forced to.
