Checking out Yahoo news and came across the following link from SB Nation looking the defensive unit "havoc rate" rankings among major college programs last season:

The havoc rate measures plays ending in tackles for loss (including sacks), forced fumbles, and tipped/intercepted passes.

Clemson and TCU topped the field, with OSU clocking in at number 11...Sparty just ahead of the Buckeyes at 10.
