I figured as much.
Ohio State had a Top Defense last year:
1st in the Nation in Pass Defense: 150.15 ypg
3rd in the Nation in Rushing Defense: 82.8 ypg
1st in the Nation in Total Defense: 233.00 ypg
1st in the Nation in Scoring Defense: 12.8 ppg
4th in Pass Effiecinecy Defense: 98.73 rating
5th in Pass sacks: 3.31 pg
8th in tackles for loss: 7.92 pg
Ohio State also had a Top 3 defense two years ago. I don't expect that to change this season.
