The Michigan-Ohio State rivalry is getting kicked up another notch this offseason with the Buckeyes taking an assistant from the Wolverines. Ohio State announced the hiring of Michigan defensive line coach Greg Mattison as its new co-defensive coordinator. Mattison will serve in the role with former San Francisco 49ers defensive backs coach Jeff Hafley.

"I love the idea of having two coordinators on defense," said Ohio State coach Ryan Day of the hires. "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.

"Jeff is a rising star and highly regarded as one of the best secondary coaches in the country. His NFL knowledge coaching the secondary is only going to enhance and improve what has become a marquee area for the Buckeyes. Greg is a terrific coach. His experience as a coordinator and his knowledge of the Big Ten is extremely important to me.

The Buckeyes recently lost co-defensive coordinator Alex Grinch to Oklahoma. Greg Schiano, who served as co-defensive coordinator with Grinch, looks to be headed to the NFL.
