There's a big difference between not scoring a bunch while moving the ball, and not scoring a bunch AND not moving the ball.

Dead last, against a Dolphins team that ranked 22nd in yards allowed last year. Dead last in 1st downs this week as well, with 9. Single digit first downs, only team in the NFL to pull that off. 21% on 3rd down, 33% on 4th down.
Oh, and the worst time of possession in the entire league.
I subscribe to the theory that you're never as bad as the worst you look, and never as good as the best you look, but man, this was just a horrible offensive showing. To be comparing them to those offenses is night and day at the moment.
