So you could say that Jim Harbaugh was less than pleased about a pass interference call against Jabrill Peppers.

The Michigan coach thought the Penn State receiver was guilty of offensive pass interference. Instead, the Wolverines were dealt the flag.

That led to a classic Harbaugh freakout on the sidelines:

Maybe he was still livid about the overturned targeting call, too.
