Ohio State’s defensive backfield stunk in 2018, but it probably wasn’t the fault of the players on the field. Ohio State’s defensive problems, their coverage lapses, missed tackles, and downright strange personnel decisions came not from the talent making (or not making) the plays. It came from a coaching staff that lasted just days after the coach that had hired them retired and handed the job over to new head coach Ryan Day.
Safeties coach Alex Grinch lasted two days. Defensive coordinator Greg Schiano and linebackers coach/the best man at Urban Meyer’s wedding Bill Davis lasted five. Cornerbacks coach Taver Johnson was seemingly never formally let go, he was just replaced by Matt Barnes.
