And no, it's not the lack of running IMO. I don't have the stats but I'd speculate that many runs inside the 10 result in no yards or a loss. Probably averaging less than two yards a carry in that situation. I'm sure someone who knows how to find the stats can confirm or prove me wrong. Either way, I am of the belief that a run that probably won't score, and may not get you any yards at all, is mostly a wasted opportunity to take a shot at the end zone.
I think the QB is part of the problem as he doesn't appear to be especially comfortable throwing the ball inside when we're between the 20's. I'd guess that these throws are made even more difficult inside the 10. They develop very quickly and the QB has to be able to make quick decisions, one thing we know dak does not excel at.
Some of it has been just plain unlucky. Beasley drops and easy one. Other big plays inside the 10 have been called back by penalty. I thought he pass last game to gallup was extremely well executed but somehow, gallup did not see the pass. And let's go back to penalties; they've killed us there too many times.
I'm saving play calling for last. Everyone complains about it. But the way you can tell no one really knows what they're saying is that many of the complaints are not consistent. Of course more people want more runs but like I said, I don't believe that the solution (or else a preschooler could have found it). Some people want to run zeke up the middle, some want to run outside, some want a read option. Basically whatever did not work that last play was the wrong one even though we've seen many of them fail recently.
In terms of passing, some wants slants, some want fades, some want picks. Well, the truth is none of us really know what they're running on pass plays unless it's a fade. We all saw how lucky we got on cooper's last TD. Basically, the db can take away a slant or a fade if they decide to do it (last play not withstanding). But the bottom line on play calling is that most fans don't really know what they're looking at, aside from the fact that it didn't work. Now, this is not to say the play caller should get no scrutiny. His job is to help the team score. I just think complaining about specific plays we should or should not run is pointless and always hindsight thinking.
So in the end, I place part of the blame on the qb that is not so good at executing passes in tight spaces, and he often holds the ball too long, leading to sacks or penalties. I place part of the blame on the OC because the buck stops with him but I'm not going to pretend like I know what he should do differently (because I don't). And I place part of the blame on luck. I mean, how many times have we had a first and 10 right at the 10 yard line this year? Seems like a lot.
