Harbaugh has been in Michigan since 2015.
2015 Michigan finished 3rd in their division with a record of 10-3. They did manage to beat Florida in the Citrus bowl, 41-7.
2016 Michigan finished 3rd in their division with a record of 10-3. Florida State beat them in the Orange Bowl 33-32.
2017 Michigan finished 4th in their division with a record of 8-5. South Carolina beat them in the Outback Bowl 26-19
2018 Michigan finished tied for 1st in their division with a record of 10-3. Florida slaughtered them in the Peach Bowl 41-15.
Michigan is 1-9 when they play top 10 teams.
Just wondering how much rope Michigan will give Harbaugh and how much more they'll tolerate before they move on.
