QBranking.com was created to add flexibility to the standard passer rating which was adopted by the National Football League in 1973. Although the passer rating was never intended to be a quarterback rating, it has increasingly been used as such by fans and media. How often do you hear football commentators criticize a quarterback's performance based solely on their passer rating? Never mind that interceptions and incomplete passes may not be the quarterback's fault. Maybe the ball was perfectly thrown but dropped or deflected right into arms of a defender. Or maybe a quarterback has benefited from skilled players that routinely turn 5 yard screen passes into 80 yard touchdowns. QBranking allows us to compensate.

For example, you can set the interception component weight at 60% and, say, the yards per attempt weight at 140%. In this scenario, Sid Luckman's 1943 season ranking increases from 107.55 to 114.719, while Tom Brady's 2007 season ranking decreases from 117.718 to 112.51. 

In addition to assigning weights, you can substitute yards per completion for yards per attempt. It's always bothered me that two of the four components are basically measuring the same thing - completion percentage and yards per attempt.  For example, a quarterback who throws a lot of short passes for a high completion rate will have a similar yard per attempt as a quarterback who throws a lot of long passes for a low completion rate. Using yards per completion allows for distinction and avoids redundancy.

Statistics were gleaned from Pro-Football-Reference through a very tedious process of going through every team that ever existed, looking at their career passing statistics, and then copy-and-pasting the data using the CSV feature they have (thanks PFR, your site is fantastic.)
