QB Passer Rating

It is arbitrary and capricious, and makes little sense,  a perfect game by a QB would need to be 100 percent completion rate, no fumbles or negative plays by said QB, and a victory in said game. This is what a perfect QB rating actually is. 

Ok, so let's say your receiver drops a perfectly thrown pass. Does that mean you didn't play a perfect game because your teammate screwed up?

 

I think the metric shows that if you perform at a certain level, you essentially max out your chance to win. You could perhaps do better, but if you are performing at a 158.3 level, you are basically playing perfect football as a QB and giving your team the highest possible chance to win.

 

And it is weaker as a one game stat anyway. It is stronger the more games you add. I remember Geno Smith had a season with the Jets where he had a game with a perfect 158.3 rating as well as a game with a perfect 0.0 rating. That has to be rare.

top 5 in order  last year were Tua, Mahomes, Jimmy G, Hurts and Geno   So not sure it has a ton of merit but it heavily favors completions percentage/west coast style short pass offense

Passer rating, to me, has always served as a general “efficiency” metric. There’s an argument that completions are weighted too heavily, but as we know, most WR average over 10 yards per catch and running backs anywhere from 6 to 8, so completions usually equal extending drives. 
 

As with any efficiency metric in sports, there’s a way to game the system to inflate the metric (namely, checking down and taking safe completions). That doesn’t make the metric invalid, it makes it imperfect. 

Not to mention that short, sustained completions eats away the clock and keeps the ball away from the other offense.

And those QB's were a combined 52-20 wins/losses last year. I'd say there is definitely correlation with passer rating and winning, and I'd bet the statistical analysis would bear that out if you ran the numbers.

What are you evaluating with the “eye test”? A subjective judgement of who is the “best qb”? An objective judgement of who is the best passer?  or something else?

It's definitely subjective which is why you have these objective measurements.  The areas that come to mind that are pry impossible to measure are how complex the offense is, what the QB is asked to do, and the quality of the personnel around them (coaches and players).

Team passer rating differential is the most predictive stat (outside of actual points scored and given up!) in all of football: https://www.si.com/more-sports/2011/06/23/most-importantstatpasserratingdifferential. Right now, the Bills have a team passer rating of 106.7 and opponents' collective team passer rating is 66.4. 

 

It's a good stat despite not being perfect. 

ANY/A is the QB stat most correlated w winning which is why among other reasons I prefer it when measuring QB performance

 

So I don't know if ANY/A differential is measured but that's what I would use.

Agreed. Also hurdles and angry run stiff arms should count. 

Subtle jabs at the opposing teams' silly emoticon t-shirts after a touchdown should count as well.

This kind of makes sense actually. If you are only hitting at a 50% rate and have SIX HUNDRED yards, your wide receivers are doing OBCSCENE work and you are being way too risky with that ball lol. Bringing in a hyper-unrealistic scenario doesn't really prove anything. The important thing to ask about a metric is, if you watch a bunch of games and understand its general score distribution, does it match up with what you saw from a quarterback in that game? Usually it does for me, at least it does it better than QBR which I believe is not even open-source. And it's not like anyone who hates passer rating has a better metric they point to and rely on. The reality is, any time there exists something that can theoretically be quantified in one easy number there will be humans who try to do it because it's a useful tool.

Thanks- there was obviously an explanation for the "random" numbers, because nobody who develops metrics for anything just makes stuff up like OP implies. Cool to have the explanation, and that's usually the gist of it, shaping the distribution of performances so it is a bell curve around some mean to reflect the reality of the performances 

Ah, but you've identified the snag with this method yourself 

I already said ANY/A is a better metric

ANY/A is a flawed metric because a QB who goes 1/9 for 90 yards is rated the same as 9/9 for 90 yards.

I don't like either passer rating or QBR.

 

As for passer rating, as I understand it, it's about efficiency and not about productivity.

 

For example, imagine a QB plays an entire game and goes 3 of 5 for 50 yards.  The reason he doesn't throw much is because he sucks so the OC doesn't call many passing plays.  But because the D is entirely focused on the run, the QB was able to complete 3 of his 5 attempts.

 

Imagine a different QB completes 30 of 50 passes for 500 yards.  Statistically, it's the same game: 60% completion rate, 10 y/a, and all that.  But this QB was an unstoppable force, throwing on nearly every play and racking up the yards.  

 

Passer rating doesn't measure productivity, only efficiency.  It would rate the two performances equally. 

 

That's like saying a RB with 2 carries for 12 yards had as good a game as a RB who had 30 carries for 180 yards.  Both averaged 6 ypc.  But one back influenced the outcome of the game in a meaningful way, the other didn't.

A QB who passes 50 times for 500 yards and zero TDs must’ve done something wrong lol

But it’s a similar argument against passer rating. It disproportionately eliminates efficiency whereas passer rating disproportionately favors it.

Passer rating favors completions, not efficiency

 

If they took the completion/attempt out of the equation and left the YPA alone it would be ok, still doesn't account for sacks

 

any/a also has more realistic relative values for TDs and INTs imo

Can't disagree  My point is a game manager qb with a strong run game is going to look better in this system  All 5 of those qbs had good to great run games

The only positive thing that happens from passing is completions. That’s part and parcel to the rules of football.

 

Not all completions are equal. But if you aren’t completing passes, nothing good is happening.

Completions are baking into YPA is my point

 

There's no logical reason why a completion should be worth upwards of 20yards when a TD is only worth 80

Josh getting the “perfect” 158.3 brings to mind the issue I have with the Passer Rating.   It is so dumb.  So, Josh got the “perfect” score.  Was he perfect? No.   Did he complete all his attempts?  No.  Many QBs have received the perfect rating and there is no common defined data for them to get it.

 

First, I’ll take that part on.   To me, a perfect score should be for a QB throwing one pass for a TD for 99 yards.  The only way to match that should be to go 2 for 2 with both passes for 99 yard TDs.  Their system is flawed.  There are 4 calculations based on Pass Attempts, Completions, Passing Yards, TD Passes and INTs.   
 

One of the calculations is:

 

d = 2.375 -  (INT/ATT x 25).   
 

WTF!!  Where did they come up with the 2.375?   What does the 25 represent?
 

Then there’s a comment that if any calculation is greater than 2.375, it is set to 2.375.  If any result is less than zero, it is set to zero.  What?!!!

 

Many numbers we experience in life in the US of A are based on tens and hundreds.  Why do they have a perfect score be 158.3?
 

 

I agree there is a flaw. but I think you take it to far with the 1 pass for 99 yards argument. 

IMO it should be perfect Attempts/Catches no INTs or Fumbles.  If you go 24 for 25 thats not perfect. The QB would score high just not perfect. It should represent perfect execution from the QB for the game

No, they aren't.  Yards are baked into YPA. 1/10 for 100. 10/10 for 100. Same YPA. 9 completions NOT baked in.

yes they are lol, they're right there. you're just figuring out that maybe they're not as important as you think

How could they be there?

 

The YPA is the exact same if you complete one pass vs 10 passes.

 

Football is predicated on achieving 10 yards to achieve first downs to sustain drives. A QB who completes 1/10 passes for 100 yards is achieving the same yardage, but not contributing outside of one play. A QB going 10/10 for 100 yards could be contributing to multiple scoring drives. A QB going 1/10 cannot by definition of the rules of the game.

 

YPA exists with this gigantic blind spot. It's not that great of a stat lol.

 

You want to say completions are overvalued in passer rating. I think that's a fair critique. But they are essentially neutralized in YPA because getting lucky with a broken play is the treated the same as methodically driving on a defense.

 

Tua has consistently been a top leader in ANYPA (#1 last year, #1 this year). Is it because he is the best QB in the NFL, or because he has the some of the best big play weapons in the NFL?

 

Brock Purdy is #2 this year.  Is he the best QB? Or is it the same thing as above?

 

Josh had less ANYPA than Jared Goff last year lmao. Your stat ain't that great.

Tua has consistently been a top leader in AYPA (#1 last year, #2 this year). Is it because he is the best QB in the NFL, or because he has the some of the best big play weapons in the NFL?

Josh had less AYPA than Ryan Tannehill, Jared Goff, and Jimmy G last year lmao. Your stat ain't that great.

any/a is the stat i use. I don't know what apya is. Allen was 6th last year behind hurts, tua, mahomes, goff, garoppolo. passer rating would have put him 8th..not a huge difference

 

the point about completions is known...you aren't going to be able to convince me that a completion for zero yards has significantly more value than an incompletion. If you believe it that's fine.
