Somehow we’re already a quarter of the way into the NFL season. Time definitely flies when you’re having fun—as is always the case with an opportunity to watch the great game of football.
With that said, there’s a lot to talk about this week, with several new names entering the fray, while a ton of quarterbacks are moving up and down the power rankings after the fourth week of action.
Playing well one week does not guarantee a move up the rankings. This list bases quarterback performances directly off one another, so even though QB "X" may have had a better game than last week, he still is not a lock to maintain his current status among his peers.
Every current starting quarterback in the NFL will be considered and valued through numerous categories, each weighted differently as the season progresses.
I factor in several key attributes for the quarterback position such as intelligence, arm strength, accuracy, athleticism and leadership.
Wins throughout this season will also give quarterbacks a slight boost in addition to their individual performances based on several metrics. These statistics come exclusively via ESPN.com, NFL.com and ProFootballFocus (subscription required), unless stated otherwise. Personal observation and opinion will also play a key role each and every week.
In the end, the essence of a power ranking with regard to quarterbacks really should consider this question: If I had one game to win and needed a quarterback to start for me, who would I want as my guy?
In order to best find this ever-changing answer, the consideration of previous years will diminish with each passing week. As it currently stands, there isn't much weight given to the past anyway. It factors about 10-15 percent given the four-game sample size in the 2013 season and will only get smaller as the year evolves.
