I think we all know by now that Cooper Rush is a high-IQ quarterback who makes quick decisions but doesn't have great arm strength. The Commanders essentially challenged him to go deep and if they weren't so handsy with our receivers, it would have worked.
He completed one of the deep play-action passes (to Brown, two were interceptions erased by penalty and at least one other turned into pass interference. Those were all go routes.
Even though we scored 25 points with help from those penalties, I would think this would be considered the blueprint for beating Rush. Play the run and the short stuff and force Rush to try to go over the top. With better corner play, there's a good chance you'll be able to catch up before the ball gets to the receiver unless it's a throw like he made to Brown, which happened only once on those routes.
