For a second straight weeks, concerns about officiating are coming out of Ann Arbor. Pass interference calls over the last two Saturdays have been of particular concern for Jim Harbaugh and Michigan.

On Saturday, a pass interference penalty was whistled on a Michigan defender as a pass was intercepted during the Notre Dame game. It was a questionable call (at best) in real time. When the replay slowed down the play, it was pretty clearly a blown call.

Below is the replay of the play in which Michigan was called for pass interference:

There’s really nothing there. And instead of a turnover for Michigan, the Irish were able to get the ball into the end zone to make the score 17-7. It ended up not mattering in a 45-14 victory for the Wolverines.

Still, secondary coach Mike Zordich isn’t happy about the call. While meeting with reporters on Wednesday, he vented a little bit about the missed call, saying he wants more “clarity” from the officials.

The video of Zordich was posted by Angelique Chengelis of the Detroit News.

This the second straight week Michigan’s staff has been unhappy with the officiating. After last week’s 28-21 loss to Penn State, Harbaugh said it would be “interesting” to see the difference between some of the flags that were thrown against Michigan vs. the plays that Penn State was not penalized for.

Needless to say, there’s been plenty of frustration with some of the officiating that’s happened the last two weeks.
