The Buckeyes will be replacing Schiano with former MI defensive line coach Greg Mattison and former San Fransico 49ers assistant Jeff Hafley.
While Urban Meyer is no longer calling the shots in Columbus, Mattison does have that connection, as he coached under Meyer for his championship Florida teams.
Ohio State lost one of its previous co-defensive coordinators, Alex Grinch, to Okahoma over the weekend. "I like having a diversity of opinion, but even more I like the expertise and experience that Jeff has in the secondary coupled with the expertise that Greg (Mattison) brings to the front seven".
After speaking with two people close to the situation, speaking on the condition of anonymity, we're told that Mattison is expected to accept a position at Ohio State, coaching in an unspecified role. His NFL knowledge coaching the secondary is only going to enhance and improve what has become a marquee area for the Buckeyes. When Jim Harbaugh took over the head coaching job, Mattison was retained, but as defensive line coach. The only other defensive coach mentioned was Larry Johnson, who will be the team's associate head coach in addition to the defensive line coach.
Considering Mattison celebrated his 69th birthday in November 2018, it's hard to imagine he plans on being Ohio State's defensive coordinator for the next decade. He'll replace Greg Schiano, who was let go recently according to BuckeyeGrove.com's Marc Givler.
Mattison first coached at MI under Gary Moeller and Lloyd Carr from 1992-1996.
Mattison comes to Columbus after spending the last eight seasons at MI.
Ohio State's defense gave up 5.6 yards per play in 2018 and had a tendency to give up big plays.
