A part of the fanbase gave up on him a long time ago and another will never give up on him. I’m in the middle but lean more towards not giving up on him. Has Michigan met expectations under Harbaugh? no. Has Michigan beat Ohio State under Harbaugh? No. Has Michigan played in the Big Ten championship game under Harbaugh? No. 3 big no’s but he’s mostly checked off the rest of the boxes. He’s won virtually every game he’s supposed to win (at Iowa in 2016 and the bowl game vs South Carolina are the only 2 you could question) and of his 13 losses, 11 have been to teams that finished the season ranked in the top 16, 9 have been to teams that finished in the top 8 and 3 have been to playoff teams. Yes he should occasionally win some games that Michigan is not favored in but it’s hardly a reason to fire him. 3 of his 4 seasons have ended up double digit wins, 2 of the 4 have ended up with BCS bowls (or whatever they call it). 2 of the 4 seasons they were in a projected playoff spot until the last regular season game. So yes he needs to make the leap soon and have a season where he goes to a big ten title game or ideally make the playoffs but at the same time I think he’s done more than enough to justify his job. I know fans are total lunatics here, but if everything you just described happened at Bama or Texas, and they went winless against Auburn or Oklahoma respectively, that coach’s seat would be red hot. I don’t root for or against UM or Harbaugh, but it seems like he gets a pass from the media at least.
