Your players here need to be very strong run defenders, don't have to be as athletic, but need to rush the passer in a pinch.

The bold part is a bit off - collapse the pocket, sometimes, but never really pass rushers. A 1 gap system relies more on the 3-4 DL applying pass rushing pressure than a 2 gap system. You'll notice sometimes that a 2 gap 3-4 will also put a DL on watch for a draw ( Dorsey often has this role for the Chiefs, hanging out by the line vs working upfield ). All depends on the system, game plan, and play call.
