Ryan Day is moving quickly on organizing his staff. According to reports, the new Ohio State head coach has already named his new defensive coordinators.

Monday afternoon, it was reported by Rivals.com that Greg Schiano would not return to Ohio State in 2019 after serving as the program’s defensive coordinator for the past three seasons. Following that news, Pete Thamel of Yahoo! Sports reported that Jeff Hafley, who served as the defensive backs coach for the San Francisco 49ers, would become a co-defensive coordinator for the Buckeyes.

The other co-defensive coordinator will be Michigan defensive line coach Greg Mattison. WolverinesWire also reported Monday that Mattison was leaving Ann Arbor after his eighth season with the program.

Hafley hasn’t been on a college sideline since 2011, when he served as the defensive backs coach at Rutgers. Mattison, however, has a lengthy career in the college game.

Day took over as Ohio State’s head coach on Jan. 2, following the team’s Rose Bowl victory over Washington on New Year’s Day.

The newly-appointed head coach is wasting no time in assembling his staff for the 2019 season.
