Since 1932, NFL quarterbacks have thrown a total of 755,936 passes, and completed 413,777 of them, for an overall completion percentage of .547.
This is 5,179,019 yards (2,942.64 miles).
Interestingly enough, there is only an average variance of about 4.164 yards per completion.
The passer rating, based on overall totals, is 71.7, with a median of 68.1.
Of course, the completion percentage and passer rating (which was not established until 1971), have climbed relatively steadily since 1932, but I suspect in the near future there will be a "leveling off" of both.
This is just a start. I'm still parsing out some of the data, and I hope to have something more in-depth soon. I really want to break things down by decade and by the number of teams in the league. I think that would make for some interesting data.
