And to follow what AB was saying allot the time, but also if the defense is up field past the QB in the X time he should be able to be pivoted the defense towards the QB for a sack. Coverage sacks are okay, but both sides need to earn their merits. That's why we spend time tweaking OLB (loopers) to make that coach turn the board off in X amount of seconds. All in all it should be the choice to continue to rush or drop for the pass, neither should be eliminated. And as far as "mugging" of the Wr's; I say in the first burst (snap) you bump then release make the defense play D and the offense make a play. Just my take.
