The NFL season will sometimes show us what we want to see from players; other times, we may see something bad when it isn't there. For fans and media, it's essential to have a way to verify and balance information to prevent favoritism or bias from being portrayed in a negative light.

Thanks to PFF, we will always have an extra set of eyes to examine the football game.
