When Ryan Day was officially named the head coach at Ohio State, he made big changes to the Buckeyes' coaching staff, and particularly on defense.
It wasn't all that surprising considering how the 2018 season played out. Despite talent at every position and within multiple levels of the depth chart, the Buckeyes defense was routinely gashed.
It started right out of the gate with Oregon State hanging 31 on Ohio State in the season-opener. The Buckeyes only surrendered three points the following week to Rutgers (which doesn't count because Rutgers), but the leaky boat continued to sink.
