NFL passing offenses have steadily improved for decades, making statistical comparisons between today’s quarterbacks and those of the past almost meaningless. In 2018, quarterbacks are playing at all-time high levels: The league average in passer rating, touchdown percentage and completion percentage are all the highest in NFL history.
But that changes when quarterbacks are playing against the Bears. Against Chicago, passing numbers have been set back 30 years.
The average passer rating of quarterbacks facing the Bears this year is 73.0. That’s by far the lowest in the league and well below the league average passer rating of 93.1, and to find a year when all quarterbacks played as badly as quarterbacks play this year against the Bears, you have to go back 30 years: 1988 was the last season when the league average passer rating was below the 73.0 rating the Bears are allowing this season.
