If you lose 38 - 40, yes you failed to score enough points, but scoring points was not the problem.
When judging / ranking offenses people use scoring not yards, just like on D people use scoring D not yards D.
We were bottom half of the league in scoring.
And doing so favors passing teams. Do you think its a coincidence SEA, SF and CAR led the NFC in wins and all 3 were near the bottom in passing yards per game.
