We have to break the season into two parts with this offenses. For the first 10 games, the offense was very effective. There wasn't much garbage times yardage accumulation because the Cowboys were in most of those games or at least were moving the football. The Green Bay game was the only one where they fell behind by a lot early. But in that game they were running and throwing effectively. But they kept giving up the ball or committing stupid penalties to kill drives. The Vikings game was close too. The Vikings are a really good defense and the Cowboys moved the ball well on them. They had to throw it but it was working because the Vikings were giving up the passing game to stop the run.
But the last 3 games, particularly the last 2, the offense has been almost as putrid as the defense. I blame Dak for most of that. He has regressed to the Dak with poor mechanics and it shows. But there have also been dropped passes, poor blocking, penalties and some bad play calling. They gave up on the run too soon against both the Bills and the Bears. I thinks it more than just good defense. The Vikings have a good defense and the Cowboys did okay against them. The Redzone offense which was so good early int he year has been horrible. It like they get inside the 15 yard line and have no idea what to do next.
I think Dak's issues can be corrected. He just needs to focus on setting his feet when he throws. I also think they can adjust the play calling to help him out. Definitely run the ball more.
I think the problems on defense are going to be hard to resolve. They may be short a few horses on defense to ever been really good.
