I've said it for a couple years now -- Ohio State simply doesn't have anyone on their defense that strikes fear in other teams. They don't have it in the secondary, they don't have it on the defensive line. Eichenberg was the only guy I was impressed with on their defense. He showed vast improvement, IMO.
OSU has had a national championship offense the last two years and a soft defense. Bringing pressure and stacking the box helps nullify getting pushed around, but it opens the defense to exactly what Michigan did to them. Long runs, big pass plays. You leave everyone on an island. It is the EXACT same defense Don Brown used at Michigan when OSU would put up 50-60 points on us.
