Harbaugh was critical of the officiating in Michigan's 30-27 double-overtime defeat against the Ohio State Buckeyes, per Adam Rittenberg of ESPN.com:
I'm bitterly disappointed in the officiating. Can't make that any more clear.
Two penalties called all day [on Ohio State]. Multiple holding penalties let go, multiple false starts. The official on my side, who is supposed to be watching that, is concerned about whether our coaches are in the [coaches' box] or not. Their coaches were on the field, practically in the huddle at times.
Wolverines fans were particularly incensed with the spot of the ball after J.T. Barrett's one-yard run on fourth down in double overtime. The Buckeyes picked up a first down after officials reviewed the play and determined the call on the field should stand.
ESPN.com's Bill Barnwell thought Harbaugh and Michigan's collective frustration was misplaced since the Wolverines had allowed Curtis Samuel to gain eight yards on the previous play:

Harbaugh should be furious - so many of those referees had a chance to make a tackle on that third-and-9 swing pass and didn't wrap up2016-11-26 21:36:00
Harbaugh also pointed out what he felt were bad calls earlier in the game, according to USA Today's Nicole Auerbach. He highlighted a pass interference penalty on safety Delano Hill in the fourth quarter as well as an incident in which the Ohio State defense impeded wideout Grant Perry on a pass in the second overtime.
Given the stakes of the game, it's easy to see why Harbaugh was so upset. With two losses, Michigan will have a hard time getting into the College Football Playoff.
Should Colorado beat Washington in the Pac-12 Championship Game, the Wolverines may secure a semifinal berth. In that scenario, they will have beaten the Pac-12 champion as well as the Big Ten champion—be it Wisconsin or Penn State.
