During the offseason, Football Outsiders publishes a wealth of interesting quarterback statistics from the previous season. These include play-action splits and pressure splits, which have not been released yet for 2016, and passing plus-minus, which I will be discussing here. The usefulness of these stats is that they use their tracking data to provide context to each quarterback’s performance. For example, pressure splits describe how often quarterbacks are pressured and how they perform when under pressure relative to when they are not pressured.
The yearly passing plus-minus articles are written by Scott Kacsmar and debuted last year (covering the 2015 season).
