In 2010, only five QBs threw for 4000 yards, with guys like Brady, Rodgers, Roethlisberger, and Romo missing the cut. In 2009, ten QBs threw for 4000 yards. There have been 48 total 4000-yd seasons in NFL history, and 36 of them have happened in the last four years.
So it's pretty clear that the game has changed so that 4000 yards is not nearly as impressive as it used to be. Incidentally, Namath was the first ever 4000-yd passer, back in 1967.
I'd be more interested in a points per yard stat, or something to that effect, and how it translates to winning.
Not to be nit picking or anything, but, I don't think you have the stats quite right. According to the website you listed, it's not "48 total 4000-yd seasons" it's 48 total QB's who have thrown for 4000 yards, a total of 110 times. Here's the quote from the website:
Overall, there have been 48 different quarterbacks who've passed for 4,000 yards in a season. The group has combined to do so 110 times.
So that dilutes the accomplishment even further!
