Ryan Day only made one change to the offensive coaching staff: replacing himself with Oklahoma State offensive coordinator Mike Yurcich.
Beyond that single move, the first-time head coach didn’t see any reason shake up anything on that side of the ball. He retained Kevin Wilson as offensive coordinator, kept offensive line coach Greg Studrawa, held on to running backs coach Tony Alford and promoted Brian Hartline to full-time wide receivers coach after serving as interim coach for the 2018 season.
Day had every reason to alter the defensive coaching staff, though, after the Buckeyes allowed more than 400 yards per game and gave up far too many chunk plays.
