Lack of Execution is the coaching staff not having them prepared enough. But only so many times you can run to the sidelines before you realize it isn’t work yet they keep doing it. It’s not the players. It’s bad coaching.
Asking too much from the defense. Having no offense whatsoever is asking the defense to somehow win the game for you being on the field for most of it.
So what I haven’t seen is any of the play calling helping. No hot routes, no RBs out of the back field, few slants. These would make it much easier for the passing game.
This is honestly one of the worst offenses I’ve ever seen in my entire life. We can’t get out of our way. And I think we’d struggle even if there was no defense out there.
