OK. 6 things

Third down.

The offense has to be better on third down. They have to extend drives, let the defense rest, and at least cross mid-field more often.

On defense, they need to be able to make stops on third down BEFORE the other team crosses mid-field. I don't necessarily have a problem with a bend but don't break defense. But the defense seems to let the opposing offenses cross mid-field too frequently.
