Are you implying other sites don't do things that turn out to be wrong.
Sounds like a strawman to me...
There was no straw man fallacy present here. In fact the only straw man being presented here is by you. Nobody brought up any other sites, they only mentioned the one you brought up, PFF. You bringing up other sites is a straw man argument.

PFF Stands on it's own, doesn't matter who or what does what or how often. PFF's OL and QB grades on their own are bad, and have been proven fautly time and again. Their very own discriptions of what and how they do things bring into question their very methods.
While they might have some value to teams that know the in's and out's of each game so they can remove the errors in PFF, fans don't have that ability so the site is next to useless for the fans.
