I work for the site so am happy to deal with the questions people have regarding it.
Firstly the rankings aren't worked out by looking at stats, the stats are more something provided as a seperate entity, though often they work in tandem.
As for the low rankings of some players ... we can only go on what we've seen this year. So while we have Tom Brady down the rankings none of us would say he isn't better than some of the guys below him. But he hasn't played as well as some this year, because of the injury. We're not telling people who are best players, but rather who have played the best this year (not taking into account garbage time which we don't grade, degree of injury or level of opposition)
We aren't trying to fix the results its just through a combination of the gradings people accumulate over the season
Any questionable rankings, hit me up and I'll do my best to explain. As a team we're in the fortunate position of watching every player in detail and sharing our views (I watch way too much football as it is
) so feel confident in backing things up.
The overall rating thing was something we considered not implementing, but in the off season I'm keen to offer a feature that lets the user weight the different categories in each position.
