They use stats to create the basis of their grading system but the stats based on the outcome of the plays (that aggregate into what we football fans call "stats") are not incorporated into the grade. That's the best I can do in terms of explaining this to you. I've tried, every link from PFF has tried, yet you just keep on keeping on. LOL

PFF uses the term "context normalized-scoring," which is based upon statistics. Hell, any serious metric or analytic systems are based upon stats and expectations, and looks at what players do against those expectations, but If you don't think that stats play any part in a players grades, be wrong. At the end of the day, it's heady anyway, so everyone is not going to understand everything. I'm done with this conversation for now. But just know, it's OK to be wrong.

It's hilarious watching you crash out while being completely wrong. Every link you posted regarding player grades specifically told you that they aren't incorporating stats into these grades, that it's based on their evaluation individual plays. That sent you scouring the internet where you came back with soccer grades as some type of gotcha before you shifted to pass protection grades where you misunderstood that they were using stats to create the basis of their grading system but not in the actual actual creation of the player grades. Pointing that out sent you back to the internet to dig some more where you came back with their "Advanced Coverage Grade" metric which is separate from their player grade.

It's a piece of information. Yeah, I would expect the PFF guys to know how to use the tool they created.

PFF uses these metrics in player evaluations, and use those to come up with player grades. It's NOT separate. My god!

I never said that it was "the greatest player evaluations tool," but it is a tool. You have to know how to use the tools, so...obviously PFF guys should know how to do that.

That's separate from their player grades which is what we were talking about. But good lord this is way more important to you than it is to me and I don't really care to keep reading through the links you're desperately digging through to try to find anything to support your dear PFF. At the end of the day, I hope you're right and I hope PFF is the greatest player evaluations tool ever crafted because it sure seems like Tepper is building an analytics team that he could've just gotten with a $120 subscription.

They're explaining it, but they're still using stats, just within the context of their system. Damn, man.

You're full of it. Stats are fundamental to their system.

Which they're just using to explain how they developed their grading system. The stats have nothing to do with the way they grade a play which they explain by showing two gifs of two separate plays with different outcomes but the same PFF grade. Are you even reading this stuff before you link it? The statistics or the outcome of a play has nothing to do with a player's PFF grade for that play. They tell you that over and over in every link you post. It's literally an arbitrary system that they came up with to create a framework for grading player performance.

What are all these? Could they be stats? Coverage Metrics Several standard metrics are commonly used to evaluate players' effectiveness in pass coverage. These include passer rating allowed, yards allowed per coverage snap, completion percentage allowed and PFF's 0-100 coverage grade. https://www.pff.com/news/nfl-advanced-coverage-grade?utm_source=chatgpt.com To say that PFF doesn't use stats in its grading is simply incorrect, period.

Statistics is such a broad term, but PFF has to use them to some degree. They just have their own measurements and grading systems which incorporate some statistics in their grades.

You're right, but they also use stats in the NFL per my last post, as you're so obviously trying to deny.

Pass-Blocking Stats PFF collects many stats that help define each block. https://www.pff.com/news/pro-how-pff-grades-pass-protection?utm_source=chatgpt.com

Dude, that's a page talking about their soccer grades.

Oh Jesus, my inlaws live about 10 minutes from Legoland and I'm gonna be down there in a week. Yeah, not looking forward to it but honestly it ain't any colder here at the moment so you're not missing out. Honestly, I just don't pay a whole lot of attention to PFF grades. I just enjoy poking fun at the people who view them as gospel. Hell, at the end of the day, I hope they're right. Because all evidence is that David Tepper is one of those guys.

https://www.pff.com/news/pff-fc-all-you-need-to-know-about-how-grades-are-calculated?utm_source=chatgpt.com To establish the expectation for each grade, PFF uses statistical models. These models learn what typically happens in a given scenario for each facet of play by using characteristics of the event as explanatory variables and the given play-by-play grade as the response variable.

No need to review data according to some. What is this "data" of which you speak? Could it be advanced statistics? Surely not!

Umanmielen's confidence obviously isn't going to be squashed by much of anything. He's come to play from day one.

I love his confidence

Which grades were incorrect? Not defending LLMs in case I'm giving the impression. I'm just more interested in reviewing the data to make sure it's correct before debating it. I'd check PFF myself (got a sub) but am fn dying at Legoland in Florida while my 9yr old runs rampant.

They don't use stats for their player grades. Period. They straight up tell you that. https://www.pff.com/grades "Their system" was arbitrarily created by them. A PFF grade reflects PFF's opinion of a player's performance based on an evaluation system they constructed. That's it, that's all. It's a piece of information. It's not an end all be all of anything.

Well it saves on cash if you can rely on a rotation of guys because your front seven is so good. Ron Rivera made Kurt Coleman look like a god, for example.
