Did I hear something correct last night?

Supposedly, Kurt Warner's game against the Chargers produced a QB rating of something like 158.3. This was the ninth time in NFL history that a QB had done this in a game. His statistics were something like 24 for 30 for 390 yards, 4 TDs, and no INTs.

My question is... if this produced 158.3, wouldn't 25 for 30 be better? I know the rating system has tables and formulas but this is just common sense. He could have done better, n'est-ce pas? http://www.ChiefsPlanet.com/ubb/confused.gif

kcbob,

I think the way the formula is, 158.3 is the max the rating can be.

kcbob,
I'm not 100% sure, but I believe in the rating systme 158.3 is as high as the rating goes. It is not an unlimited measuring system.

I'm not certain what the formula criteria are and I certainly don't understand the whole thing. However, upon it's creation, it was believed that NO QB is going to connect on 100% of his passes so they set the "perfection" bar a little lower. Kinda like grading on a curve.

Well I think it's fairly obvious that the maximum rating is 158.3. Maybe I should restate my question and ask "Why is there a max in the first place?"

Then again, I could see a max if it was something like 100. A batting average max is 1.000. I understand that. But 158.3???? I'd like the drugs they were doing when they came up with that. http://www.ChiefsPlanet.com/ubb/wink.gif

Is everyone ready to attend QB rating 101??

The QB rating is broken down into 4 factors:

Factor 1:
(pass completions / Pass Attempts) / .2

Factor 2:
(yards / Pass Attempts) / 4

Factor 3:
(touchdowns / Pass Attempts) / .05

Factor 4:
(.95 - (interceptions / Pass Attempts)) / .04

((Fact1 + Fact2 + Fact3 + Fact4) * 100) / 6 = qbrating

There will be a test! http://www.ChiefsPlanet.com/ubb/smile.gif

The system is designed to grade a QB's effectiveness over the course of the season, rather than rate his performance for a single game. Thus, while a QB might complete 95% of his passes in one game, it is highly unlikely that one would complete that percentage over a season. (The season record is 70.55%.)

Same for interceptions. To attain the highest possible score on that component, a QB would have to have no interceptions for the season. (Not going to happen.)

The average yards/pass perfect score requires an average of 12.5 yards/completion. The NFL record is 11.17 and has stood since 1957.<P>

And to obtain the maximum possible score on touchdowns/pass requires that he throw a touchdown 11.9% of the time. The record of 13.9% has stood since 1943.

And not to pick nits, but the formula for completion percentage is:

((100(comp/att))-30)*.05=x

*note:if x is less than 0, x=0, if result is
more than 2.375, x=2.375

Yards gained per attempt:

((yds/att)-3)*.25=y

*note:same as above note

Percentage of TD passes:

((TD/att)*100)*.2=z

*note: 2.375 maximum value for z

Percentage of INT:

2.375-(((INT/att)*100)*.25)=a

*note:if a is less than 0, a=0

To calculate total QB rating:

((x+y+z+a)/6)*100=QB Rating<P>

Thanks guys, my head hurts now, and my screen just got blurry. My eyes lost the ability to focus.
I just fell down and can't get up.

Good, milkman. We've been in sore need of a replacement since Mrs. Miller passed.

Great Dan...just provide the opening for one of our you-know-whats to say something like:

"That just illustrates that Grbackup can't hit a receiver in-stride and allow them to keep running. They're having to dive for bad passes."

Is there a website that gives week by week QB ratings? I was wondering what Elvis got last Mon night. Thanks. I see his season rating is up over 95 http://www.ChiefsPlanet.com/ubb/biggrin.gif

But, bkkcoh, if your formulas are correct, where are the "tables"? And if it is strictly formulas, there should be no maximum. Or am I missing something?

I think that is a big reason Grbac's rating isn't higher than it is despite 12 TD's vs 4 INT's which is one of the best ratios in the league at this point. The downfield attack results in a lot of incompletions (and the 9 drops week 1 didn't help either) and thus if you have a lower completion percentage, you have a lower yards per attempt, and both pull your rating down. This is a major reason why the short passing offenses of the West Coast offense give QB's higher ratings, because they throw short quick passes and let the recievers work after the catch, which improves completion % and thus yards per attempt...

Mr. Dole:

I used the stats for EG the last 3 games and got a qb rating of 105.2. This is close to the 105.4 that is listed on the Kchiefs.com site.

If one of the components of my rating is as far off as you say it is, how could I be within .2 of being correct. I figured this is just off because of rounding inconsistencies.[sp]


kcbob, check out post #9 as far as the limits the factors can be.

So what's with these mythical "tables"? Now it sounds like it's all a straight-forward(?) formula.

Thanks, all.

bkkcoh:

Bob Dole doesn't find where Bob Dole stated you were "far off." If your formula produces results within 99.81% of the NFL's convoluted calculation process, Bob Dole would vote for it without reservation.

Bob Dole was simply pointing out that is not the "Official" method of calculation.

(Bob Dole thinks maybe you were directing your comment to someone else...)

kcbob:

Bob Dole can't figure out what you're talking about with the "tables" comments. It's pretty easy to create a spreadsheet that allows you to enter the QB stats and spits out the results, and there are Java and Flash based calculators floating around on the web.

Bob Dole likes <a href="http://www.brucey.net/nflab/media/rating.html">this one</a>.<P>

Kcbob,

Here is the link to some of the information Mr. Dole was giving out.
