Pro Football Scout 365: Defensive Efficiency Rankings Examines Havoc Rate W/3rd Down Stops.
What is Havoc Rate? Havoc Rate is a popular stat used to measure the aggressiveness of a defense by taking the total number of sacks, INT, fumbles recovered and dividing the total of all three by the total number of offensive/defensive plays. How can we use Havoc Rate to measure offensive/defensive efficiency? The answer is simple, the team with a lower havoc rate against their offense, does not allow sacks, INT's, fumbles and converts third downs. The opposite is Defensive Havoc Rate which takes the same stats (sacks, INT's, fumbles and 3rd down's not converted) divided by total defensive plays to get a defensive havoc rate. The obvious difference is that you want a higher havoc rate on defense. Defensive Havoc Rate W/3rd Downs Not Converted Leader in 2018. The 2018 Chicago Bears led the NFL in defensive havoc rate with 50 sacks, 27, INT, and 9 fumbles recovered (8.5% havoc rate). Football Scout 365 decided to juice this stat up by adding 3rd downs not converted to the equation. The reason why is that we believe 3rd downs not converted can be treated just like a turnover. The Bears defense faced 219 3rd down attempts stopping the opponent from converting on 144 of those attempts (22.9% Havoc W/3rd not converted added). 2018 Defensive Efficiency
