The DVOA stats show the same. The offense is ranked 13th in the 1st half, 26th in the second half.
We are also pretty terrible for every scoring differential except being ahead by 2+ scores, which goes back to what I said at the beginning of the season about passing efficiency being the differentiator between good and bad offenses. It’s great that we can run the ball well when ahead, but we need more firepower in the passing game for the running game to matter against decent or better opponents.
