As part of a package on Peyton Manning's record-setting season at ESPN.com, I've put together a list of the top passing seasons of all time. Each season since 1950 was translated to the modern offensive environment, and then I developed a "quickie" method to estimate PAR based on conventional numbers rather than play-by-play breakdown. Even after taking into account that offense is up around the NFL in 2004, Peyton Manning isn't the only quarterback having a historic season.
SackSEER grades the 2014 class as a historically strong group of pass-rush prospects... but the player making the most history comes out as a disappointment.
