In a nutshell, the Steelers defense rattled the Bills. Chalk it up to whatever you wish: Allen getting limited time in preseason, Dawkins getting COVID, Diggs not being 100%. The bottom line is the Steelers smothered the Bills offense. They were never fooled and never out of position. They closed plays like a guided missile. It was a punch in the mouth that should tell us we ain't all that we think we are.
