Tim Drevno's run as Michigan's offensive coordinator/offensive line has come to a close and Ed Warinner is expected to join the team's coaching staff, a source with direct knowledge of the situation tells the Free Press. The source requested anonymity because Michigan has not made these moves official. An athletic department official did not have a request for comment earlier Friday. The news was first reported by TheWolverineLounge and Sports Illustrated's Bruce Feldman. Both reported that Drevno opted to resign. Per the source, with Drevno on his way out, Warinner – who was hired by Harbaugh as an offensive analyst earlier this offseason – is expected to step in as Michigan's new offensive line coach. What Michigan does with its offensive coordinator title remains to be seen. Though the Wolverines did hire former Florida head coach Jim McElwain to be the team's new wide receivers coach earlier this week.
