With Week 17 now officially in the books, the NFL's wild regular season has come to a close.
2013 saw record-breaking performances by newcomers bursting onto the scene ready to bring about a new era in NFL quarterbacking. However, several tried-and-true veterans proved they were not quite ready to relinquish their crown and give up superiority to the next generation.
In a passing league, only the teams with capable quarterbacks can survive. This is a comprehensive list of the best signal-callers in the NFL today.
Because it is the final ranking of the season, every quarterback who saw significant playing time in the NFL will be considered and valued through numerous categories, each weighted differently throughout the season.
I factor in several key attributes for the quarterback position, such as intelligence, arm strength, accuracy, athleticism and leadership.
Wins 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.
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.
