Following last week’s announcement that co-defensive coordinator Alex Grinch would be leaving Columbus after one season to take a position at the University of Oklahoma, multiple reports are now surfacing that the Buckeyes’ other defensive coordinator — Greg Schiano — is on his way out as well, and that a rather surprising name might be taking his place.

BuckeyeGrove’s Marc Givler is reporting that Schiano will not return for the 2019 season; and while he didn’t have any sources as to who would officially be taking his place, he did indicate that a coach or two from TTUN were on Ryan Day’s radar.

In fact, in a separate report by 247Sports’ Sam Webb, it seems that 69-year-old defensive line coach Greg Mattison is leaving the Michigan Wolverines’ sideline to join Day’s staff. Mattison is a staple in college football, having worked at Michigan in the 1990s before leaving to coach at Notre Dame, Florida under Urban Meyer, and then as the linebackers coach and defensive coordinator for the NFL’s Baltimore Ravens under John Harbaugh.

Mattison returned to Ann Arbor in 2011 as the defensive coordinator under Brady Hoke, and was retained by Jim Harbaugh as the defensive line coach.

Reports also indicate that Day would like to bring current Wolverine linebackers coach Al Washington to Columbus as well. While this is just conjecture, it would seem as though Day is going to keep with the recent OSU trend of having co-coordinators on both sides of the ball. With Kevin Wilson and the recently hired Mike Yurcich on offense, and potentially Greg Mattison and a younger co-coordinator on defense.

The other names rumored to be up for a D-Cor job under Day would be Michigan’s Al Washington and Cincinnati’s Marcus Freeman — of course a former Ohio State and NFL linebacker as well.
