Drevno has been the offensive line coach and offensive coordinator for three seasons and the offense has continued to struggle. He accepted an analyst job with the Wolverines last month. Warinner was Minnesota's offensive line coach in 2017 before leaving for MI. He was Ohio State's offensive line coach in four of his five seasons, and he also held that title at Notre Dame, Illinois, Kansas, Air Force and Army. Warinner will be Michigan's offensive line coach in 2018, according to FOX Sports' Bruce Feldman. Wilton Speight left the Purdue game and was lost for the season with a back injury, while Brandon Peters missed the second half of Wisconsin and the Ohio State game with a head injury.
While the offensive line showed marked improvement in the running game throughout 2017, it wasn't enough to salvage an abysmal offensive season in which the Wolverines ranked 105th in the nation with 348.9 yards per game.More news: Most Active Stock: Southwestern Energy Company (NYSE:SWN)

MI hired Jim McElwain as wide receivers coach earlier this week and he would seem to be a respectable candidate to step in for Drevno, though 247Sports is hearing that the program has not yet decided their next move. The former National Football League player and Florida Gator spent four seasons in the National Football League with brief stops with the St. Louis Rams, Cleveland Browns, New Orleans Saints and San Diego Chargers.
