Espn QBR
 
I saw this on FF and thought I would pass it along in here

Drew Brees

Terrelle Pryor

Colin Kaepernick 10/16 164 yards 1 td 7 carries 54 yards 2 TDs
Passer rating of 117, but a QBR of 99.8

Basically, if you didn't know this already, QBR is one of the worst stats in football...it is just a big jumbled mesh of numbers that ESPN through together and they refuse to give the formula out to the public.

QBR is a messy made up garbage stat...passer rating, which is a very simple formula which just takes the 4 main categories of passing and treats them evenly, is still the best method to date, although even that is flawed obviously.

25% COMP%
25% TDs
25% INTs
25% Yardage

^^^ that is all passer rating is, and although not perfect, it is a decent metric

QBR over the course of a season averages out and gives a pretty accurate representation of the level of play the player has been at.

Both are just quick glance stats though - if a player has a QB Rating above 95 or so....you can safely assume he's playing at a decent level.

A guy has a total QBR above 60 to 65....you can safely assume he's playing pretty damn good.

Nothing will ever come close to watching the film, but very few people have the time or even care enough to put in the time to do that.

For example, QB Rating is not without "wtf" moments when judging one individual game either.

Mark Sanchez went 12/15 for 180ish yards and 1 touchdowns and had the same passer rating as Peyton Manning who had 462 yards, 7 touchdowns and no picks.

Both stats regulate themselves over the course of a year.

I'm sure his proudest moment was when he BEAT Peyton Manning in the playoffs in Indy :hammerhead:

Sanchize has been with Eva Longoria, Jamie Lynn Sigler, Kate Upton and some SI swimsuit/Victoria's Secret model. Probably anyone he wanted at USC too.

Obvious proudest moment is obvious.

They are slightly less ridiculous over a longer period of time (they don't work at all for 1 game) but you are absolutely right.

so what Sanchez did in his FEW attempts were just as efficient as what Peyton did in MANY attempts...that one makes sense to me

Passer rating is not perfect obviously, no stat is...HOWEVER it is still much better than QBR

passer rating is a simple formula...part of QBR's issue is that no one understands it, ESPN won't release the formula...if you are going to take it seriously then you are forced to do so blindly

QBR has a place because it evaluates a QB's running ability and also weights plays different. If you're racking up yards and a touchdown in garbage time, those stats mean pretty much nothing....and QBR accounts for this. Regular QB Rating values all stats in all times of the game as the same.

I remember a playoff game a few years ago, Pats vs the Jets.....and Brady played pretty bad. But he got some garbage time stats and all of a sudden when people look back on the box score 10 years from now they'll see 300 yards, 2 tds and 1 pick and a 90 QB Rating and they'll say he played very well........

He ended up with a 8.7 QBR, which is much more representative of his play that day.

I also agree, generally, with their scores for Luck this year. When I believed he played average to below average, they had a score that correlated with that. When I thought he played well, he had a good score.

Last year anyone who watched all of the Colts knew for a fact that the regular quarterback rating was not correlating to the level of play he was playing at. His Total QBR was much more in line with reality.

Both have a place in the stat world. Both flawed.

I'd say the PFF grades are the most accurate, at least they base it off film. Although even then you could probably debate how they score for QB's....that's one of the positions I feel leaves a lot open to interpetation on the grades. It'd be interesting to grade a QB on your own using their grading system and then compare it to what the grade they give to that same quarterback.

QBR is a terrible stat. Also, no surprise a Colts fan is supporting it since it ridiculously overrates Luck.

Carbine 10-29-2013 10:51 AM

Re: Espn QBR
 
It overrates him?

He was 11th in QBR and 26th in regular QB Rating - behind Blaine Gabbert.

Exactly. For his level of play 11th was way too high last season. His season last year was so overrated.

As for him being 26th in passer rating - You have to understand that it is a per attempt/efficiency stat and per attempt last year Luck was simply not that efficient.

"Way too high"

Where does 2012 Luck in your opinion? I think you'll be surprised when you list the names out just how close he is to 11ish.

Re: Espn QBR
 
last year Luck threw a lot of INTs and his comp% was very low

he got a ton of praise for the Colts 4th Q victories and his passing yardage that naturally came with a ton of attempts

I think Luck's passer rating is more accurate than his QBR numbers...

this year Luck has a 91 passer rating, which also seems accurate...he is growing as a player
