A lot of experience walked out the door of Tim Drevno's meeting room in January.
And a new coach walked in.
It'll be a new day, a different look and an interesting year for Michigan's offensive line as the Wolverines will look to rebuild a unit that lost three starters -- and struggled to produce during big moments in all three of the team's losses in 2016.
Drevno -- Michigan's offensive coordinator/centers and guard coach -- will be joined in the offensive line room by run game coordinator (tackles/tight ends) Greg Frey this season. They'll also likely have three new starting spots to fill.
