Michigan's 2015 recruiting class looked like an all-timer in the summer.

Now?

Not so much.

Scout.com's Sam Webb reported Tuesday that 2015 five-star running back Damien Harris has officially decommitted from Michigan and Brady Hoke.

Harris is the second high profile 2015 player to back out of a Michigan commitment in the past two months, as five-star wide receiver George Campbell did the same in December.

Ranked as the No. 1 running back in the class of 2015 by ESPN.com, Harris -- from Berea, Ky. -- had been the focus of social media speculation for more than a month about whether or not he'd be sticking with his pledge to the Wolverines.

One of the main connections that tied Harris to Michigan seemed to be former offensive coordinator Al Borges.

Harris' prep coach at Madison Southern High School -- Jon Clark -- was a staffer at Auburn with Borges in 2007. After Michigan opted to fire Borges earlier this month, both Harris and his family expressed how surprised they were by the move.

New Michigan offensive coordinator Doug Nussmeier visited Harris last week. But, apparently, the effort didn't quite pay off.

For what it's worth at this point, 247sports.com reported that while Harris is firmly decommitted from Michigan, the Wolverines still remain No. 1 on his list of schools at the moment. However, he's not tied to anyone anymore.

Without Harris, Michigan's 2015 recruiting class now dwindles down to four committed players at the moment: four-star defensive back Shaun Crawford (Lakewood, Ohio), four-star defensive back Tyree Kinnel (Huber Heights, Ohio), three-star offensive lineman Jon Runyan (Philadelphia) and two-star kicker Andrew David (Massillon, Ohio).
