To some extent yeah it's an every QB issue, but this was a bad miss. TE running free up the seam against a straight cover 2 is as easy as it gets. As I said in another post in this thread IDK if its really a Dak not seeing the field issue or a Dak is being handcuffed by the coaches issue. That is one that a Rogers, Brady, even a Romo would see, make an adjustment, and take advantage of easily. Dak is plenty good enough to make that throw.
Watch it again. Then watch it again. Each time focus on Dak's head, the position of both safeties, and the linebacker in the middle of the field as the DT broke free to invade the area Dak would have stepped up.
Now offer a commentary about what the temperament would have been with a poorly thrown ball because Dak could not step into it. Throwing late which allowed the safety to come over. Or not enough gusto on the ball the linebacker wandered back and deflected it, or worse intercepted it.
And in the final analysis, what Dak saw, and what he believed he saw, also requires an understanding of where this was in the game, and how many more times Dak would have the ball back with time enough to win. If that didn't end up in the other team's hands because of the lateness of him seeing the TE.
Then factor in that McCarthy wants him to risk less. Which speaks to your comment about coaching.
I agree he could make that throw. He made some much more difficult in the game.
