Pursuit in Multiple-40

Coaches, depending on front in our 4-4, we usually ask our backside DE to chase, and our backside LB to collapse. We figure that if the run does break, the LB's better speed should help him pursue from the collapse. DT's fill their gap, then squeeze down the LOS after checking counter. We feel that if they turn and cross face too quickly, they are too prone to counter and cutback.
We assign cutback responsibility to the collapse LB and the backside ILB, who we ask to double step on any kind of split flow.
The idea of a pursuit landmark is an interesting one Coach Campbell, it would definitely help in maintaining gaps until a DT or DE is sure it's true flow away. We like our DT to anchor, and occupy OL to allow LB corps to scrape and make plays, but giving them a landmark would increase their participation in pursuit.
