Ask an Indiana offensive player what their offensive x-factor has been the last few years, and surely, Greg Frey’s name will come up.

The IU offensive line coach helped guide a rushing attack that produced thee All-American seasons from offensive linemen and four 1,000-yard rushers in the last three years.

But now, Frey is reportedly leaving Bloomington for a different B1G East school.

The Wolverines reportedly hired Frey to take over tackles and tight ends, according to Scout.com’s Sam Webb:

Michigan running backs coach Tyrone Wheatley left the program to take the same position with the Jacksonville Jaguars. With that, Jay Harbaugh will now be the new running backs coach.

Frey will technically take Wheatley’s spot on staff.

This will be Frey’s second stint at Michigan after he served on Rich Rodriguez’s staff from 2008-10. He helped coach future NFL offensive linemen Taylor Lewan, Patrick Omameh and Michael Schofield.

At Indiana, Frey was nominated for the Broyles Award in 2015 after helping IU to its most productive offensive season in school history. He had been at Indiana since the beginning of the Kevin Wilson era in 2011.

It remains to be seen what kind of impact the move would have just a week away from National Signing Day.

UPDATE: Michigan confirmed that Frey will join the Wolverines staff as the new tackles and tight ends coach.

“It is an honor and privilege to be able to return to the University of Michigan,” Frey said in a release. “I am humbled and excited about this opportunity to work with Coach Jim Harbaugh, one of the leading minds in all of football, while joining an amazing staff that he has assembled at Michigan.

“I look forward to watching our student-athletes develop as great men, students and athletes. I’m ready to get to work representing this University and football program.”
