NFL 2019: Defensive Havoc and Efficiency Through 8 Weeks

Every four weeks of the College Football and NFL season we are releasing our offensive and defensive havoc rate report. What we are looking to identify what teams are the best at creating havoc, and what teams are the best at defending havoc.

What is Havoc Rate? The Football Outsiders produce an in-depth analysis coined the Five Factors which include the havoc rate measure. We added third-down stops to go with total sacks, TFL’s, fumbles, INT. We added third-down stops because we believe that defenses that can get off of the field more often tend to be more successful even if they are doing it with lesser common havoc rate stats (sacks, INT’s, fumbles, TFL’s). We use the same metric when measuring offensive efficiency. The teams with lower havoc allowed, and a low number of third-down stops correlate to having more success.

In addition to the 2019 totals, we added the 2018 Total Havoc Rate and created a YOY differential to ID the teams who are improving vs. those who are regressing.
