With one more week of regular-season action left to be played, the QB power rankings are just about finalized. This is also true for the NFL's playoff picture.
Week 17 will be critical for some teams hoping to keep their seasons alive, while other teams look to lock down a division or home field.
It's already been a record-breaking year for quarterbacks and the fun is still going.
For these rankings, every current starting quarterback in the NFL will be considered and valued through numerous categories, each weighted differently as the season progresses.
Each week, I factor in several key attributes for the quarterback position, such as intelligence, arm strength, accuracy, athleticism and leadership.
Wins will also give quarterbacks a slight boost in addition to their individual performances. The statistics used to help determine the ranking system are pulled from ESPN.com, NFL.com and Pro Football Focus (subscription required) unless stated otherwise. Personal observation and opinion will play a key role as well.
Note: Total QBR is a scoring system that assesses everything a quarterback does on the field. It can be explained further via ESPN.
Also, Pro Football Focus grades every single play of the season to generate a cumulative point total, which weighs into the metric as well.
Other key statistics considered are passer rating, touchdown-to-interception ratio, yards per pass attempt, fumbles lost, rushing yards per game, completion percentage, etc.
