I have seen Dallas defense point out the play and defend it before the snap of the ball. There is a ton of film every team looks at and no one is throwing new stuff out there. Hell every game I watch it is not hard to figure out what a team is about to do, if I can figure it based on down, distance and tendency of a team I know damn well NFL teams know it too. I'm glad Cooper pointed out about the stop route and how Philly was defending it and disappointed that Linehan does not use certain plays to setup a different play. DB will normally back off on stop route out of fear of the double move and getting beaten deep, Dallas and Linehan need to do better about setting up plays off of base plays they run.
I would also add Dak has to make those changes as well at the line of scrimmage based on the coverage
