Ohio State's defense took a lot of heat for its lapses in an October loss at Oregon. What's different for the Buckeyes in the Playoff?

The Ohio State defense has been playing lights out since the match-up with the Ducks, giving up less than 12 points per game and the secondary hasn’t allowed a passing touchdown since that day in Autzen Stadium. On the other side, the Bucks are a patchwork on the offensive line. The unit has performed well at times. Other times, not so much.
