With the second week of the NFL season officially behind us, the quarterback situations across the entire league are beginning to shape up. Some QB's have taken a significant fall from last year, while others are on the rise heading into these updated QB power rankings after Week 2.
This week brought us a new starting quarterback in Jacksonville, while we may have seen the last of one in Cleveland, at least for a while.
Playing well one week does not guarantee a move up the rankings. This list bases quarterback performances directly off of 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. Considering we're in the early stages of 2013, I am currently putting more weight on last year's performances along with this year’s preseason.
In addition, I have given consideration to a quarterback's long history of stellar play by factoring in his total career "Approximate Value," courtesy of Pro Football Reference. I've also given points for Super Bowl victories.
After that, 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 ranging from basic to advanced.

Personal observation and opinion will also play a key role each and every week.
