| 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.)
