The offense definitely had their ups and downs this year but lets look at the numbers...

Scored 20+ in 13 games. 8 teams (including the Giants and Texans who are in the playoffs) didn't average 20 ppg for the season.

Scored 30+ in 9 games.

29.3 ppg for the season, 2nd in the NFL

Meanwhile our defense was 31st in the NFL giving up 28.4 ppg.

By these numbers, the offense had plenty of weeks where they scored enough points. I don't get what your vendetta is with the offense. Sure it wasn't what we've seen when we were at our peak but our offense is better than most. However, you can't overlook how bad the defense has been not only this year but for a while now.
