The playcalling is fine. Dak has to pull the damn trigger. The OL is giving him plenty of time. Again, Dak has to pull the damn trigger.
The NFL has figured him out. Load up on Zeke, zone out the middle of the field so Beasley can't hurt you there, make sure the left defensive end doesn't fall for the play-action bootleg, and keep Dak in the pocket. Cowboys solved.
Romo would laugh at these fronts. They're 70-yard touchdowns waiting to happen. Then, they'd have to back off, and Zeke would have room to roam. That's what the elite veterans do.
