Someone said earlier I have to break down all the 3rd downs. Said I would. Got started. Saw this. Here's what I got on the first 3rd down after the penalty-

2:53 in the video
3rd & 14
Def- Cover 3, 4 rushing
Offense-
Schultz & Pollard in backfield, Coop Wide Right, CD slot right, Gallup wide left
Gallup runs a post, CD a corner, Coop a go, Pollard is the check down and Schultz stays in to block. First read is at Coop. Nothing there. There's a window for Gallup right after the cut in his route, before pressure is an issue. Pollard has the underneath defender occupied. Pressure comes and Dak rolls right instead of stepping up past the guy Schultz rerouted. Might not matter anyway. Gallup is throwing up his arm as he goes through the route. Possible 2nd window but Dak is on the move and that's a tough throw.
So why didn't he recognize the coverage and go to the backside post window earlier?
Here's the necessary caveats- this is 1 play. This is how I saw it. All QBs miss reads. I saw the next is a 3rd down conversion which could very well be all positive all around.
