The defensive tackles have been manhandled today. That's worrying.
Rutgers is the 2nd best rushing team in the Big Ten. So factor that in.
The rest is only concerning if all of the DBs are hurt for the year.
Denzel Burke is, legitimately, the best defensive player on the team and the second best player on the team. He just cuts the field in half. No one throws at him. Makes all of the safeties jobs way, way easier.
