How is QBR calculated?

This makes no sense....They saying he had a bad game

Total quarterback rating - Wikipedia

it's not a good formula for game by game basis.

but obviously it definitely has some merit for seasonal basis


Single-season QBR leaders[edit]
The following is a list of the ten all-time best single-season leaders of the QBR statistic in the NFL:[20]

How is Total QBR calculated? We explain our quarterback rating

Examines all of a quarterback's contributions

ESPN’s Total Quarterback Rating (Total QBR), which was released in 2011, has never claimed to be perfect, but unlike other measures of quarterback performance, it incorporates all of a quarterback’s contributions to winning, including how he impacts the game on passes, rushes, turnovers and penalties. Also, since QBR is built from the play level, it accounts for a team’s level of success or failure on every play to provide the proper context and then allocates credit to the quarterback and his teammate to produce a clearer measure of quarterback efficiency.

Leaving out key areas of impact can make a quarterback’s performance look very different. Omitted from Cousins’ stat line, for example, are his 6 sacks taken, 3 fumbles (1 lost) and 2 pre-snap penalties on Washington’s offense. Rodgers, on the other hand, took only one sack, did not fumble and drew a number of defensive penalties that kept drives alive. Each quarterback impacted the game through these plays, but none of them are reflected in the traditional stats.

The lack of context for each play also increases the distortion of the performance. Most would acknowledge that a 7-yard completion on third-and-10 is not a successful play, but base-level statistics treat all yards equally. Coaches, players and fans know what wins games; it only makes sense that the statistics that judge the most important position in the game do, too.

In the NFC wild-card game referred to above, Rodgers started slow but manufactured five straight scoring drives and posted an 87 Total QBR. In comparison, Cousins’ errors cost him the game, and despite throwing for 119 more yards than Rodgers, Cousins had a Total QBR nearly 30 points lower. QBR is a measure of efficiency, so Rodgers created far more value per play than Cousins did.

fukk QBR, I stick with the old school quarterback rating.

how did cam have a higher qbr than arod??? less tds/ less yards/ less yards per attempt/ less sacks

WTF

 

[South Paw]

qbr is trash, espn and dilfer created it

gotta use old QB rating

fukk QBR, I stick with the old school quarterback rating.

that ain't no damn better.. they basically pulling this shyt out their ass and stuck with it... might as well delete any ratings and just look at the stats.. they just adding up random calculations and making it a number "rating"




The NFL passer rating formula includes four variables: completion percentage, yards per attempt, touchdowns per attempt, and interceptions per attempt. Each of those variables is scaled to a value between 0 and 2.375, with 1.0 being statistically average (based on league data between 1960–1970). When the formula was first created, a 66.7 rating indicated an average performance, and a 100+ rating indicated an excellent performance.[3] However, passing performance has improved steadily since then and in 2017 the league average rating was 88.6.[4]

The four separate calculations can be expressed in the following equations:

where

ATT = Number of passing attempts
COMP = Number of completions
YDS = Passing yards
TD = Touchdown passes
INT = Interceptions
If the result of any calculation is greater than 2.375, it is set to 2.375. If the result is a negative number, it is set to zero.

Then, the above calculations are used to complete the passer rating:

{\displaystyle {\text{Passer Rating}}=\left({(a+b+c+d) \over 6}\right)\times 100}

QBR gives receivers most of the credit for YAC breh. so according to QBR that long TD rodgers threw was really a 11 yard pass and receiver did most of the dirty work.

and i never liked QBR cuz it makes too many assumption and favors mobile QBs. i know it is supposed to look at the context and it's kinda has some DVOA in it, but i still don't understand how many things like how they come up with expected points.

there's just too many variables and it really is not a pure statistics. and trying to understand the context has limitations. for ex. converting 3rd 20 has more expected points than 1st and 5. that's very logical on paper. but not all 1st and 5 is equal. what happens a QB avoids pressure twice avoiding jj watt and clowney at the same time and escaped to complete a hard earned 6 yards into a triple coverage? isn't that more impressive than an easy pitch and throw 3rd 20 against a blown coverage?

i get that they are trying to look at the context. but it's really impossible to really quantify it because every possession and every throw has its own story.

Keenum had a higher QBR than Rodgers despite 3 INTs

QBR sucks, real stats heads agree it's a joke of a measure

Don't worry about it at all

Basically the old quaterback rating seems like the right thing to go with. That shows really how you played cuz all these nikkas BALLED week 1

Dak Prescott last year was ranked 4th in QBR but 17th in Quarterback rating.....Clearly Dak ain't the 4th best QB in the league but 17th last year seems more accurate.

it's definitely better than QBR, but passer rating also have some limitations too. it puts too much emphasis on yards per attempt and it's only for the passing.

but it's much more reliable than QBR for sure

Stats died with Nate Silver

Unless you're talking about baseball where it's mostly 1v1
