Jim Harbaugh’s sleepover worked.

Quinn Nordin, the nation’s top kicker, once said told the Michigan coach that it would be “extremely difficult” for him to flip from Penn State.

One Harbaugh sleepover and official visit later, that was accomplished.

Nordin announced on Wednesday that he committed to Michigan over the likes of Penn State and USC.

Nordin visited USC last weekend, and had maintained a relationship with former Michigan special teams coach John Baxter, who left for Southern California at the end of the season.

But in the end, Nordin will stay in his home state.

The three-star Rockford, Michigan native gave the Wolverines another boost on what’s already been an eventful signing day.

Michigan landed four-star cornerback Lavert Hill over the likes of Michigan State and Penn State earlier in the day. Hill was also one time a Penn State commit.

The Wolverines currently boast the seventh-rated 2016 class in the 247sports rankings, but they could get a major boost if consensus No. 1 recruit Rashan Gary chooses Michigan over Clemson.

And for the record, Harbaugh didn’t sleep in Nordin’s room during their highly publicized sleepover.
