Fellow Steelers fan! I was telling people this before the seasons started - of course it helps when you have the DL and LB the Steelers have. Fast, physical and smart. The whole point of the 3-4 is to cause chaos, make the QB think and rush every play. We never blitzed once under Diaco. The 3-4 doesnt work without a blitz. I love the defense because if your corners are good, the pressure on the QB causes mistakes and when your corners are bad, the QB can't get the through off/your helping contain with the zone.
