The Will linebacker to the left rushed with the linemen creating a four man rush. The Sam linebacker was responsible for the fullback. One middle linebacker dropped as a robber into the middle of the field and the strong safety came over to cover the slot receiver. The other middle linebacker was responsible for the tailback.
All of the receivers had man to man coverage and the help came in the middle of the field about 10 yards deep and then deeper in the middle of the field with the free safety. Jackson just had to blow by his guy and make the "skinny cut towards the middle of the field where the free safety had no time to catch him. It was a great call and great execution.
