Their grading system is an opinion poll. They take each play and have random people rate their opinion of a players performance on a scale from -3 to 3. They call it a grade but it is exactly the same method of the "strongly disagree to strongly agree" opinion and psych polls everyone has seen which typically range from -2 to 2.

That makes it subjective. Do you need to be explained why subjective statistics are fraught?

Further muddying the waters is that there is a different number of graders each with their own subjective evaluation doing each of these player grades.

That makes normalization between each player -something they do not even try to do- impossible.
I don’t neee anything explained to me. At the end of the day their grading system isn’t lying. It’s grading great players high. And piss poor players low. Diggs is the rare guy who these ratings fail. I’m not defending them but their grading system isn’t any better it worse than anything else out there.

Shutdown corners limit options for the opponent.

INT's change games. They can even change seasons.

Never mattered to me if Diggs could be considered a shutdown, especially after only two seasons. Give him a few more seasons and he will be both if he isn't already.

Give me a playmaker over a shutdown any time.

I remember a game vs the Giants; Romo had a couple of TDs, no pics, high YPA and completion percentage. And we won the game.
Eli had a pic and several bad misses and basically was worse in every statistical area and the Giants lost; by the way the last time the Giants had the ball he was lousy.
And PFF said that Eli rated better for that game.
From that time on I treat PFF as it deserves.
Like the Garbage it is.

I don't trust PFF but I do trust my own eyes when I see #7 catching the ball and going the other way with it.

Trust your eyes! What a novel concept.

Some fans would rather trust what PFF tells them, even though they have already seen it with their eyes!

I don't understand the criticism of PFF. They're giving Diggs the 2nd highest 'adjusted' coverage rate of all CBs since 2006.
You really don’t understand the criticism?

When their ratings 1st came out he was considered a below average CB. Now he is considered one of the best CB’s.

Darrelle Revis never had more than 6 Ints but he changed the way the Jets could play defense for years. Diggs isn't doing that for us, so while his play is fine and his INTs certainly help make up for plays he has given up, it's not like he is shutting down half of the field. I think the question is would people be saying the same thing if Diggs had 4 INTs instead of 11, which is far more likely where that number will be this year? Maybe we would.
1st of all no CB has ever shut down half the field. The best CB’s of all time had the ability to shut down a teams best receiver, but not half the field.

Diggs is a very good CB. Believe your eyes, not PFF.

The first & most apparent reason Diggs has a lower grade than you might expect is that he gives up a lot of yardage between interceptions.

It’s what the people here do.

Jerry used to spend big in free agency and fans said: “Jerry is trying to buy a championship. That’s why Dallas is always in cap hell. He throws money at free agents because he can’t draft. You can’t build a team that way!”

The battle cry of the mad fan then: “Special Teams draft!!!”

Now, the front office thinks you pay too much in free agency for big ticket players, and fans say: “Penny pinching Jerry and Stephen can’t do free agency. They just want to save money by only using the draft. You can’t build a team that way!

The battle cry of the mad fan now: “Dumpster diving!!!”

There is more to running a FO than going for broke and spending everything you have, and then not doing anything at all and just trying to get freebies. Those are two extremes that are usually done by people who have no idea what the heck they are doing. Don't have much grey matter necessary to decipher on when to pay and who to pay. That takes football knowledge. This is what these knuckleheads lack. So both cases above are true.

It’s not flawed. Alll I’m saying is it’s generally saying what it’s suppose to say. I’ve never seen them over a season call a bum a great player or vice versa.

PFF is a source that uses their own analysis to measure how good or bad players are. It isn't perfect, so it's up to the particular audience member to use their own discretion to determine the merit of their claim.

I generally take it with a grain of salt. For some reason, PFF gets people's panties in a bunch. That's probably 65% of their schtick. It actually works well for them. Because when people whine, other people will go click to see what the whining is all about, etc. And sometimes, those people end up being consumers of PFF.

PFF be like, keep whining; send them our way.

I agree. There’s no perfect stat or analytical tool that can accurately gauge how good a player is. I think you can take some bits and pieces from some of them to help with your own conclusion.
