Jim Harbaugh hasn’t been one to bite his tongue. He’s willing to say what’s on his mind if he feels it’s necessary.

Following Michigan’s 28-21 loss to Penn State on Saturday night in Happy Valley, the Wolverines head coach talked about some potential inconsistent officiating that occurred throughout the contest. He wasn’t nearly as adamant about bad whistles being a factor as he was after the Ohio State game in 2016, but you could tell there was some frustration.

Early on, it seemed like Penn State did get the benefit of two non-calls that could’ve easily been whistled as pass interference. There was also an illegal man downfield penalty that cost Michigan a touchdown. Harbaugh spoke on a few of those calls after the game.

“It’ll be interesting to compare some of the different scenarios in the game in terms of the calls,” Harbaugh said in the postgame presser. “Lavert [Hill]’s holding penalty that resulted in a touchdown [for Penn State] on third-and-11, versus a couple of those at the end. Some of our receivers were getting tackled there the last couple plays of that drive.

“It’ll be interesting to see the lineman down field, the one they called on us and took off a touchdown compared to — especially the one that stands out in my mind was Hawkins going for an interception and a guard knocking him away. So, there’s a few. The OPI they called on us for the OPI that I thought should have been called on them on their first touchdown.”

There did appear to be some contact that went unnoticed early in the game, but whether or not it was a consistent theme throughout the contest is up for debate. Michigan still had plenty of chances to win the game.

Michigan dropped to 5-2 with the loss and is now 3-2 in B1G play this season. The Wolverines will host Notre Dame in Ann Arbor next Saturday.
