New Ohio State coach Ryan Day has announced two additions to the Buckeye defensive coaching staff, and those moves signal the end of Greg Schiano’s tenure as the OSU defensive coordinator.
Former Michigan assistant coach Greg Mattison will join the OSU staff as the co-defensive coordinator, along with former NFL assistant coach Jeff Hafley. Current OSU assistant Larry Johnson will continue to work with the defensive line and also assume the duties of associate head coach.
Hafley will coach the secondary and Mattison’s position assignment is to be determined.
Schiano spent three years as the Buckeyes’ defensive coordinator. Changes with Ohio State’s defense were likely after the 2018 defense set school records for yards allowed in a season. The defense was specifically susceptible to the run, allowing seven touchdown runs of 70 or more yards this past season. Former co-defensive coordinator Alex Grinch left OSU last week to become the defensive coordinator at Oklahoma.
Mattison has spent nearly 40 years as a college defensive coordinator or assistant coach. He served as the Baltimore Ravens defensive coordinator, as well. For the past four years he’s served as Michigan’s defensive line coach, where the Wolverines have put together one of the top ranked defenses in the nation during his tenure. He also previously coached with Urban Meyer at Florida.
Hafley coached with Day in San Francisco. He’s worked with the 49ers defensive backs for the past three seasons, and before that he worked with the Cleveland Browns secondary for two years.
“I love the idea of having two coordinators on defense,” Day said in a news release. “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 brings to the front seven…”
“These are two outstanding coaches and they will provide stability, wisdom and a fundamental approach to everything they teach. They will add to our culture while proving to be excellent coaches and mentors for the young men in our program.”
