This defense is looking more like the one Mike Nolan ran these last 2 weeks, unable to stop the run with any success, result of limited pass rushing opportunities and offenses seeing easy run/pass options in 3rd and manageable distances.
The issues aren't within just one area, it's throughout the personnel and defensive scheme:
-We seen huge gains on the ground both inside and on the edge.
-Defensive Line stunts have created huge rushing lanes to exploit, where backs get to the 2nd level with ease.
-Using 3 safety looks over more of a traditional alignment makes it harder to defend the ground attacks.
-There are some issues with the personnel throughout the unit.
-Lack of discipline or so called gap responsibility.
Some possible solutions:
-Quinn needs to dumb down his scheme, no more stunts/twists up front, has to be more conservative.
-Bring back more of a traditional front with a linebacker replacing Kearse inside the box.
-Play bigger personnel, Zimmer used to employ 2 1 Tech's inside, we might have to do the same. 3-4 Fronts were established to defend the run better, maybe use that alignment more.
-Bench players who freelance and lack discipline. Make them accountable for their play.
-Offense needs to force teams to pass the ball more often by playing ahead.
