Does Anybody know what a QB Rating is?

[wayne1218]

They were talking about this on the radio today and for the life of them, they couldn't figure this out. Drew Brees and Tom Brady had fantastic days yesterday.

Brees - 23/30 369 yds 4 TD/0 Int Rating of 156.8
Brady - 29/34 380 yds 6 TD/0 Int Rating of 152.8

Brady had a much better completion %, more yards and 2 more TD's. How in the world does Drew Brees have a higher rating on the day? It makes absolutely NO Sense to me. Anybody??

Any sacks?

Maybe throwing the ball further downfield???

[wayne1218]

I have no idea. I do not think either of those factor in but it is baffling to me really.


I feel stupid not knowing exactly what a QB Rating is but after talking to people today, it seems nobody understands it.

They did find something that said if Brady had thrown for 425 yards instead of 380 that he would have had a perfect rating of 158.3

What?

Huh??


They didn't know why either.

Does the defense they are playing factor into it? I could see that factoring into Brees rating.

[wayne1218]

So sacks do not count, just the stats i listed.

Now it makes even less sense mavs. I thought there would be something i'm missing but i guess not. WTF?

Nope, just the stats i listed and the link mavs provided still doesn't explain anything except the stats they use ... and now i'm more confused!

Here's another link that list yds/attempts in the formula:

Quarterback Rating Formula

It's a very complex formula, that me you or anyone else on this site can't comprehend.

Brees had a better yd per at 12.3 to 11.2

It looks like that is factored in too. So that trumps more yards, 2 more TD's and a much higher completion %? Makes no sense to me. You think Comp. % would be at the top of the list for a QB Rating?

[mavskidd02]

I believe the amount of TD's is factored in very little. I believe the TD:INT ratio is more important than TD's themselves. Which in this case, Brees and Brady have an equal ratio.

I could be wrong however.

I'm not sure either but td's have to be somewhat a factor if it is 1 of the 4 or 5 things asked for in that link you provided. I would assume completion % would be most important but i guess not.

a = (((Comp/Att) * 100) -30) / 20
b = ((TDs/Att) * 100) / 5
c = (9.5 - ((Int/Att) * 100)) / 4
d = ((Yards/Att) - 3) / 4

a, b, c and d can not be greater than 2.375 or less than zero.

QB Rating = (a + b + c + d) / .06

Using the formula above, here is where it comes from:

Brees:
a = 2.333
b = 2.375 (capped)
c = 2.375
d = 2.325

Total = 9.408 / .06 = 156.8

Brady

a = 2.375 (capped)
b = 2.375 (capped)
c = 2.375
d = 2.044

Total = 9.169 / .06 = 152.8

So, basically what is hurting Brady is the d, the yards per pass attempt. He is also "hurt" by the capping on the first two. Basically, completion percentage component (a) is perfect and then some, his TDs per attempt is perfect, his INTs is perfect, but his 11.1 yards per attempt is worse than the differences between the categories where Brees is behind him.

It it was uncapped like they do in college BRady's would have been higher. But, with the NFL's system it's behind. But the answer to your question would be the yards per attempt.

Nevermind. Apples post explains it all.
