PFF says we have the 8th WORST pass rush?

To be honest I don't agree with PFF's take on our pass rush. It doesnt match with what i've seen on the field.


However, I think we find out if they're correct this week. Tre is obviously out and Benford is practicing with a red jersey, so he may be out. If the pass rush is really a benefit of great coverage then we may realize it on Sunday morning.

 

No, things aren't determined on one week.  

 

And no, if you're down to the 3rd and 4th string corners, your passing defense overall takes a hit.  Just like any team who is down to the 3rd and 4th positional players in any area.

Either your pass rush can get home independent of pass coverage or it can't. 

 

This is true to an extent because you also have to take in context.

 

You don't know what changes an offense will make when facing 2 starting corners vs 2 back up corners.  What do offenses typically do against back up corners?  They attack them.  Well now against 2 back up corners, you have more open.  Back up corners typically are separated on more so QB's see windows quicker.

 

If the QB can get the ball out in under 2.5 seconds consistently, then the only pressure you're getting their are missed assignments and whiffs.

 

I expect teams to get the ball our quickly against us and attack the corners....especially Elam.

Note the big difference in win Percentage.

PFF considers every down as equal. It is not a situational statistic.   Top ranked team wins a lot more of the battles according to their review of the games. 

I can't personally confirm or deny because I don't am not going to review the games at that level of detail.   But they accurately count the sacks and pressures, so it is not like their analysis does not understand sacks and pressures.

PFF has a substantial adjustment in scoring based in the market size of the team for which a graded player is employed.  Skewed for larger markets

 

Can you share a link?  Really interesting.

Am I reading Ed Oliver as a mediocre pass rusher correctly at 58 rating?

It's a flawed stat, but PFF grades pass rushers on their "win" on the initial rush at the snap.  It's like an extension of training camp discussions where we talk about DL X "winning their rep" against OL Y or vice versa. All those sacks against Washington would not count as pass rush wins because they were due to Sam Howell holding the ball too long. Why did he do that? Because the BIlls DBs took away his first read. In the end, it doesn't really matter. All that matters is that the defense made a play. But just like with PFF OL ratings, they are trying to quantify something that is not really quantifiable but because as humans we love numbers and rankings we eat it up.

That's not true... It's a symbiotic relationship between coverage and pass rush

 

Your pass rush could get home fast allowing your corners to not cover for a long time.. masking bad corners

 

A great pass rush could get neutralized by Max protection.. and if you don't have the defensive backs to cover you will lose downfield

 

And a great secondary can also make quarterbacks hold the ball longer.. allowing less of pass rushers to get home ..

 

There are a lot of ways it can happen

Just because you do not like or agree with the grades do not mean that they are trash. 

Every single NFL team as well as 80+ college teams pay PFF for their data. And it's not because these teams like to waste money.

Like I said, good or bad, they're grades are trash. It's not about me liking it or not. I couldn't care less.

 

PFF gets plenty of raw data, which is great. However, they are not football analysts. They are not qualified "graders."

 

Teams pay for the raw data. They are not paying PFF to grade and analyse their players. If they are, they're failing.

Are these calculations all over the map intentionally ? To cause conversation ? I’m not sure why some of these results are so absurdly contradictory to what you’re actually watching.

 

 Are they just determined to be smarter than the old guard prior to analytics. Strange.

 

Yes, but posters can't help themselves so they rush to post it. PFF has literally said they do stuff to rile up fanbases for traffic.

I made it up, but typical follow the money.  NFL Radio is 40%  Cowboys and Cowboys have been meh, forever.  Good D, but meh.

It is all about the money and in review PFF over the years, I don't trust them and it is usually about the fans dollars

None of this changes the fact that a d-line can either get pressure without db help or they can’t.

 

 

Synergy is not the conversation. Individual component effectiveness is.

 

It’s akin to saying “XYZ quarterback can either make plays with a bad o-line or they cant” and someone responding “QB play and line play is synergetic”.

 

Well, yeah… it is… but that doesn’t change the. fact that either the QB can make plays with a bad o line or they can not.

Since this is a PFF thread, I thought I'd ask - has anyone read the new book about PFF from Matthew Coller (ex-WGR producer) yet? I'm thinking about it since I've always wondered how exactly they attempt to normalize these grades across the many different things they grade and across all the different graders they employ. I know PFF provides apparently useful analytic data to tons of teams; and I don't really have a doubt they have a bunch of talented numbers guys there. The grading system on the other hand seems to produce head scratching results frequently. 

 

Link to book I'm talking about.

You can have the best d line in the world... And if the other team block 7 you're not getting pressure..

 

Then you need defenders in the back that can cover

 

It's not as simple as you make it sound.. there are lots of moving components on every play... And even the greatest d line can get neutralized with a game plan so you need to have more

 

And that wouldn't make it the d lines fault... Because 7 beats 4 and 5 usually... You're not generating pressure... So you need defensive backs that can cover 

 

It's a chess match out there

 

It's certainly not as simple as your front can create pressure or not... Because you can neutralize the best front with Max protection..  then it's not creating havoc

 

And you need to have people in the back that make plays

Not gonna lie, PFF made me feel a little better last week when it claimed Tre White's rating thus far this season was something like 63, but in the back of my mind I was also thinking "yeah but they're also full of *****".  And not even a week later, we have a reminder of why that is.  Smh

PFF has a stat PRP: A formula that combines sacks, hits and hurries relative to how many times they rush the passer. This ignores win percentage. 

Ed Oliver ranks 16th in this stat.  (ahead of Nick Bosa).  Maybe this can make fans feel better.  I find it helpful if people actually understand the things they are bitching about.

In no universe is Ed Oliver remotely close to Bosa. 
 

Just because they throw a bunch of numbers at you that somehow make sense to them (they don’t), doesn’t mean they’re accurate in any way. 
 

Bunk.

You don't really understand it.  Its barely worth the time to explain it.  But the PRP measurement is a totally objective measurement, and there is no dispute about the components going into it.   As an an analogy, pretend its early in a baseball season, and some random hitter like Ty France is 20 for 40 and batting .500.  And Aaron Judge is  8 for 40 and batting .200.    Your concept would be "its bunk" to say Ty France has a higher batting average than Aaron Judge.   
 

It would be very simple minded to assume that someone publishing the batting average stat is claiming Ty France is a better hitter than Aaron Judge. They are just publishing a statistic.

As if anyone needed any more evidence that PFF is a joke.

 

 

Is there any forum where they get challenged on crap like this? It sounds pretty indefensible. 

 

On a side note, why do all these people on TV sound funny?    😋

I understand it just fine. It’s garbage. And your analogy doesn’t work.

Yep! I prefer watching the football games. I don’t know what we get this week with Groot out and Von unlikely to play much, if at all. But if you watch the games it’s obvious….they are GETTING AFTER THE QB!

Well, that is just a terrible analogy. I mean TERRIBLE! We are watching football, and judging what we are watching. I don’t feel a need to ignore the facts to date.

 

I don’t care if you are watching a new guy, or a guy in pin stripes. You seem to be suggesting that we are (according to some subjective opinion) that one is better than the other, therefore we should grade on some kind of a curve. That works for biased people who are not objective about the football we have seen this year, but I’m not buying that crap.

Individual pressure rates, QB hits, sack percentages, etc. are all really strong for many of the individual players on the line and collectively.

 

PFF is spouting BS on this.

Anything can be analyzed, and a scoring system established to determine results.  The more complicated the input variables the

less the results can be judged successfully.

 

Football is an extremely complicated game.  There are 22 players on every play all with assignments that can change in a split second.

Any system that tries to analyze a football play without knowing exactly what that play is and the counter opposing defensive call is

problematic at best.  Everything in football is to create confusion for the opposing side.

 

The reason there are so few good QBs in the NFL is because it's a tough game to control.  That chaos is hard to minimize and the speed

between a successful play and an unsuccessful play is frighteningly fast.

 

Data and analytics are useful but attempting to rank everything from 1 to whatever is extremely difficult.  While I can applaud the attempt

to do this I take it with a pretty big grain of salt.  No one knows this more than NFL coaching staffs IMO.
