ALLENDALE — Jim Harbaugh shook up his offensive coaching staff this offseason.
But he's still not sure whether or not that new-look staff will feature an offensive coordinator.
Speaking with reporters at Grand Valley State's football camp in Allendale on Sunday, Harbaugh said he hasn't decided whether or not he'll formally name an offensive coordinator before the start of the 2018 season.
Michigan currently has passing game coordinator Pep Hamilton, offensive line coach Ed Warinner and wide receivers coach Jim McElwain on staff.
