Today, we’ll look at some of the defensive trends under first-year defensive coordinator Jeff Hafley, including blitz rates and coverage usage among other trends.
The Packers' defense finished the season as the 4th most efficient defense in EPA/play (-.066) and 7th in defensive DVOA. Not too shabby for Hafley and his wholesale change from a 3-4 under Joe Barry to a 4-3 in less than a year.
Installing a predominantly 4-3 cover-3 style defense of the Seattle scheme/”legion of boom” mold under Pete Carroll of the mid-2010s, Hafley revamped and re-styled the scheme along the way at various stops, first picking up the scheme with Robert Saleh in 2017 with the 49ers.
