If that's the case, we should be doing the same when they run screens.

But screens are not going to win this game. We need to attack their weakness - at present, if they have one, it's their defensive line. They have some undersized guys in there. We need to focus on running the ball and ball protection. With their DTs thinned out, that's our best chance. And, if we can keep them in single-high safety the entire game, we might be able to sneak in a few shots down the field.
