The shakeups on the Buckeye coaching staff are continuing.
According to BuckeyeGrove.com’s Marc Givler, Ohio State defensive coordinator Greg Schiano will not be returning to the program.
It’s been reported by 247 Sports that the new co-defensive coordinators will be Michigan defensive line coach Greg Mattison and 49ers defensive backs coach Jeff Hafley.
Defensive line coach Larry Johnson was named associate head coach as well as remaining the defensive line coach.
This comes on the heels of last week where there was reports that Michigan defensive assistant Al Washington was rumored to be taking a position on the defensive staff. With Mattison coming to Columbus, it makes more sense that Washington would be on his way as well.
Mattison is a long-time assistant coach in both college and the NFL. The 69-year-old has worked at Illinois, Cornell, Northwestern, Western Michigan, Navy, Texas A&M, Notre Dame, Florida and Michigan on two seperate occasions during his 48-year coaching career.
He also was the linebacker coach for the Baltimore Ravens during the 2008 season before being elevated to defensive coordinator for the 2009 and 2010 seasons.
His two stints in Michigan were as the defensive line coach from 1992 to 1994 under Gary Moeller and defensive coordinator under Lloyd Carr from 1995 to 1996. He returned to Ann Arbor as the defensive coordinator under Brady Hoke from 2011 to 2014 before moving to defensive line coach.
Besides working under both Jim and John Harbaugh as well as Moeller and Carr, Mattison also worked under Urban Meyer at Florida where he was the co-defensive coordinator and defensive line coach on Meyer’s staff and they won the 2007 National Championship defeating Ohio State 41-14.
Hafley has been a college assistant in Pittsburgh and Rutgers but since 2012 has been an NFL assistant coach. The 39-year-old worked under Greg Schiano at Rutgers and with the Tampa Bay Buccaneers.
He also spent time with the Cleveland Browns under Mike Pettine and was with the 49ers under Chip Kelly and Kyle Shanahan as the defensive backs coach for those teams.
As for Schiano, the rumors have been out there since Meyer announced his retirement in early December that there was a chance Schiano wouldn’t be retained as co-defensive coordinator. Earlier this week, Alex Grinch left Ohio State to become the defensive coordinator at Oklahoma.
The Buckeyes’ defense wasn’t as strong as in recent years giving up 403.4 yards per game (tied for 71st in the nation) and 25.5 points per game (tied for 51st in the nation) while also losing their best player Nick Bosa to injury early in the season.
Adding Mattison to the defensive staff looks like it’ll help as he’ll join forces with defensive line coach Larry Johnson who is one of the best assistant coaches in the nation himself.
With Johnson’s recent track record of Ohio State defensive linemen and Mattison’s at Michigan that include Chase Winovich, Rashan Gary, Maurice Hurst and Taco Charlton, I don’t expect the Buckeyes defensive front to miss a beat in terms of recruiting and on the field product once the 2019 season begins.
If anyone was worried about if Ryan Day was going to be able to carry the torch Urban Meyer left him in Columbus, it looks like Day has picked it up and is sprinting with what he’s been able to do in the short time he’s become head coach of the Buckeyes.
