Michigan has filled out its coaching staff.
U-M has hired Indiana offensive line coach Greg Frey to handle tackles and tight ends, plus serve as the run game coordinator, according to themichiganinsider.com's Sam Webb.
Jay Harbaugh, who coached tight ends in his first two years at U-M, now will coach running backs, filling the vacancy left by Tyrone Wheatley's departure for the Jacksonville Jaguars.
U-M offensive coordinator Tim Drevno will continue to work with the interior offensive line.
It's a similar setup to what U-M coach Jim Harbaugh had in his final year at Stanford (2010), when Drevno handled the interior line while Greg Roman coached the tackles and tight ends.
