It's clear that the Cowboys are a run first team. The only player on offense that other defenses are scared of is Zeke. Our WRs are possession WR that have trouble getting open. There are no deep threats on this team. Our HOF TE is not going put up big numbers. Our other RB are ok, but nothing great. When Zeke is in the game, the defense is scared of what he might do. This opens the passing game up for us. Without Zeke, our scheme is run the ball and short passes since the opposing defense doesn't have to worry about the deep pass. Dak is struggling and has lost some confidence for sure. He's been put into a position that he has had to deal with before. Last year, losing Dez for a span didn't effect him, but this year losing Zeke has effected the entire offense.
This is on coaching and scheme. The scheme is a predictable offense that doesn't try to hid what they are doing. They just line up and say, "Beat Us" if you can. Well, they can and often without Zeke.
