Ohio State's defense is currently ranked No. 2 in the country. Say what you will about the level of competition, but that's quite the turnaround from last year's unit that was plagued by missed tackles, poor angles, and busted coverages.
Revisiting the Purdue debacle is not something folks want to do, but the game in West Lafayette was a prime example of what Ohio State's defense was in 2018. Watching a 5-foot-9, 180-pound true freshman run circles around Buckeye linebackers and break tackles from safeties en route to the end zone wasn't a pleasant sight.
