As we’ve been pointing out this week, the passing numbers were off the charts in 2011. No records were safe, many fell, and many of them went to Drew Brees and the record-setting offense the New Orleans Saints put together this season.

Some quarterbacks made the previously lofty benchmarks of 5,000 yards and 40 touchdown passes look like older, mortal numbers such as 4,000 yards and 30 touchdowns. Four of the top six seasons all time in passing yardage belong to 2011, as do three of the top seven seasons in passing touchdowns.
Thought this might be a good read

The average game in 2011 consisted of:
44.36 points; the highest number since the 1965 season (46.1).
34.0 pass attempts per game per team (2nd highest in NFL history behind 34.8 in 1995).
20.4 completions per game per team (2nd highest in NFL history behind 20.5 in 2010).
All-time record-highs were set in gross passing yards per game (244.8) and net passing yards per game (229.7).
Only 2.82% of all passes were intercepted (2nd lowest; NFL record is 2.74% in 2008)
The league-wide yards per attempt (YPA) was 7.20, which is the highest since 1965.

While a lot of those numbers only put 2011 near the top, the season did break several league records in regards to passing.
