Basically, their team of "300 plus staff" give a grade to each player of between -2 and +2 on each play, and then they tweak and "normalize" those numbers in some way that makes sense to them, and finally they convert it all onto a 0-100 scale. As Dam points out, subjective input factors HEAVILY in these analyses and, by the way, what makes the -2 to +2 initial scale appropriate to begin with?
People just like this stuff because it attaches a number to a player's performance that give the impression of significance and objectivity, but looking under the hood reveals that it really doesn't and often the PFF numbers simply do not make sense - such as Leonard being ranked behind Vander Esch. These kind of things then generate lots of discussion, which has the unintended effect of boosting PFF's profile even more - so PFF isn't going anywhere anytime soon. |
It's real life Madden. Hey look so and so has a grade of 85 but our guy is a 92, he is sooooo much better. If it was really effective they would be transparent about it. I am trying to track their ratings of draft picks a few years back to see how accurate their predictions were, having trouble finding a lot of them though. Shocking.
