Who says they don't hit home more. They added better blitzers. Front 4 no pressure brings just as many problems. Time kills most secondaries not blitzes.
For instance, that Dalton throw to Green doesn't happen with a good blitz. Designed rollout to get away from front 4. If Van Noy is coming hard to the strong side, could be a sack. That couble move took time even with 7 back there.
