'Havoc rate' will likely determine success of Ron Roberts' Auburn defenses

The "havoc rate" in college football refers to the percentage of plays in with the defense recorded a tackle for loss, sack, forced a fumble, intercepted a pass or broke up a pass. The term is designed to measure the chaos a defense can create on a consistent basis, and it's a term that new Auburn defensive coordinator Ron Roberts will use over and over as he attempts to create a defense that can help the Tigers win championships.
