Keeping to their assignments is key to playing run defense. The Jets were getting sucked up inside, and the linebackers were not keeing their spots on the outside. This is where the new scheme will come in.
There will naturally be more players in the box, especially when the Jets run the “46”. That scheme brings 8, sometimes 9 in the box on one play. To put it simply, it brings more defenders into the box than the offense can block. With all the traffic on the inside, there will be freer defensive players on the outside to stop outside sweep plays.
If the Jets can get this down, the defense will be set to retake the league by storm.
As of now, they are on the “edge” of greatness.
