If it was an actual declaration of that statement, then that is some of the ridiculousness that I am speaking of. If it was simply one of their homemade grading stats that showed him excelling at one particular aspect, that is something much different, although still silly.
Either way I do agree that any kind of site that makes up their own grading systems etc is going to not only be controversial a lot, but they are going to outright fail miserably a lot too, and I think that your point is correct that we've seen that from PFF.
My only counter-point was that it is my opinion that there is still some useful information in there at times, so I personally don't automatically discredit every single stat or story here like some do, just because it's PFF.
