FireChan Posted September 27, 2014 Posted September 27, 2014 Invalid no, but it does make it so they can give a hand up to who they feel like. Example, Tom Brady is 22nd on the list with a 2-1 record and brees is 7th with a 1-2 record. I know there are other factors but that's just going by qbr. Brady put up 12 against the Raiders. Brees played way better in his games. I don't see the problem.
Orton's Arm Posted September 27, 2014 Posted September 27, 2014 (edited) I think the QBR vs. the old rating is an interesting debate. The new system definitely factors in some important elements that had previously been ignored. However, the thing about the old rating is that while it may not be great for one or two games, it's fabulous for an entire season. Outside of points scored and given up, is there a better predictor of success than the differential between a team's offensive and defensive (old-style) QB ratings? To be honest, I'm not a fan of the old quarterback rating system. John Elway's career quarterback rating was 79.9. Kelly Holcomb's was 79.2. Holcomb emphasized short, high percentage passes; thereby boosting his completion percentage. Elway didn't. Quarterback rating is going to make Holcomb look better than he should vis-a-vis Elway; because it takes completion percentage into account. Jim Kelly had a career quarterback rating of 84.4. Rob Johnson's career quarterback rating was 83.6. A QB who throws the ball away to avoid a sack hurts his rating; whereas the guy who takes the sack protects his QB rating. A third problem with quarterback rating is that a 5 yard pass + 45 yards of YAC is treated exactly the same as a 50 yard pass. YAC (yards after the catch) is an interesting dilemma for any quarterback rating system. Joe Montana would hit his receivers in perfect stride. A five yard pass could turn into a nine or ten yard gain. I could easily see giving Montana credit for a significant portion of that YAC. But if a QB throws a screen pass to a stationary WR, and if that WR then rips off 45 yards of YAC, it's not clear why that YAC should be treated as though it was air yards. (Which is how quarterback rating treats it.) Unlike quarterback rating, QBR attempts to differentiate between YAC for which the QB was at least partially responsible, and YAC that was purely the result of the efforts of the receiver and his blockers. Unlike quarterback rating, QBR takes down and distance into account. Suppose a quarterback completes a 5 yard pass on 3rd and ten. That completion will be pretty good for his quarterback rating. But it will hurt his QBR. Edited September 27, 2014 by Edwards' Arm
Kelly the Dog Posted September 27, 2014 Posted September 27, 2014 Yes, I know...I'm having a moment of hopefulness. It'll pass in about 15 hours, at the latest. I assume when you say 15 hours you mean 15 minutes, yes?

Do I need to dissect how patently absurd that statement is? It is akin to saying that we can't complain about a lifetime .200 hitter in baseball cause he is 2-4 today which makes him a .500 hitter on the day.

The Wiz Posted September 27, 2014 Posted September 27, 2014 (edited) Brady put up 12 against the Raiders. Brees played way better in his games. I don't see the problem. I agree with Brees having better games but some of the metrics they use that skew the numbers. Staying with these two guys vs vikings. Brees had a huge game 27/35, 293 yards and 77% completion. Passer rating of 120.3 but a QBR of 79.8. Brady against the vikings went 14/21, 149 yards and 66% completion. Passer rating came out to be 103 but a QBR of 86.5. That's my issue with the "clutch index" and "probability to win" based on the passing game. If you are winning 24-7 and throw a 4 yard dump off it increases the probability to win. I understand it should increase because keeping the ball when you're winning increases your chances of finishing the game that way. But then compounding the probability to win with the clutch factor when you're already winning increases the total QBR. The QB isn't doing anything more or less than he has all game but is getting additional points because of it. JMO. EDIT: Also Brees threw 2 TD, 0 INTs and Brady threw 1 TD, 0 INTs. Edited September 27, 2014 by The Wiz
Boolay Posted September 27, 2014 Posted September 27, 2014 All these fabricated QB ratings are useless. Bottom line you want your QB to get yards passing, throw TD's, avoid interceptions and generate first downs on passing situations consistently. Any system that rewards a QB for a 2 yd pass on 3rd and 9 is worthless.

There was a 16 game stretch during which the Ravens went 15-1, with Trent Dilfer at the helm. Those 15 wins included playoff wins and a Super Bowl championship. On the other hand, there were plenty of times when the Broncos went 7-9 or 6-10 with John Elway under center. I do not believe that Trent Dilfer was a better quarterback than Elway. Nor do I believe that he played at an above-Elway level during that 16 game stretch. What I do believe is that the Ravens were much better at non-QB positions than most of the Broncos teams for which Elway played. Citing a QB's "record as a starter" ignores the fact that football is a team sport, and that non-QBs can also affect the outcome of games. I agree with Brees having better games but some of the metrics they use that skew the numbers. Staying with these two guys vs vikings. Brees had a huge game 27/35, 293 yards and 77% completion.

I agree that on the surface, it seems odd that Brady's QBR against the Vikings was higher than Brees'. I'd have to dig deeper into the stats before concluding why this was the case. If (for example) Brady was much better at converting third downs, or avoiding fumbles, or something of that sort, then his higher QBR would not necessarily reflect a flaw in that metric. But if Brady was merely being rewarded for the fact his team was in the lead, then it probably does demonstrate a need to improve QBR. My impression is that the much-discussed "clutch factor" weights how heavily each play is graded. If the game is on the line, your plays will count three times as much as plays in garbage time. Also, if your team has pretty much won the game, then that reduces the "clutch factor" associated with whatever short, safe passes you throw after your team has secured victory. Meaning your early game plays (when both teams still had a chance of winning) are more heavily weighted than your late game plays. But if you're still not sold on QBR, there's another, much simpler statistic which reveals many of the same things as QBR. This statistic is air yards per attempt. (After clicking on that link, it will be necessary to sort the list by air yards per attempt.) Air yards per attempt isn't the right tool with which to measure every quarterback. Suppose that Joe Montana throws a 5 yard pass to Jerry Rice, hitting him in perfect stride. Because Rice didn't have to slow down and wait for the ball, he was able to get 4 yards of yards after the catch (YAC). Montana deserves his share of credit for that YAC; and air yards per attempt wouldn't give him any of that credit. But let's say a QB doesn't have Montana's gift for hitting receivers in perfect stride. In that case, air yards per attempt is a perfectly valid measurement tool. It strips away the things the receiver is able to do on his own, after the catch. It gives the QB credit only for the portion of the play for which he was personally responsible. 67.7% of Manuel's total passing yards have come because of YAC. That's the third highest percentage of any starting quarterback in the league. Through the first three games of the season, Manuel is averaging 2.28 air yards per attempt--the third worst average of any starting quarterback. There are eleven quarterbacks averaging over four air yards per attempt. One of whom is Ryan Fitzpatrick. Manuel is not currently playing like a top-25 QB--at least not if his stats through the first three games are any indication. I assume he'll be given at least the rest of this season to try to improve.

San-O Posted September 27, 2014 Posted September 27, 2014 (edited) Serious question: why is that half of football a good representation in comparison to the other 25 halves he's played in the NFL? Well, first let me say after posting and reading and watching the Bills and E.J. play, most people are going to see whatever they want to see. I believe it shows what his game is about, or how the Bills are using him anyway. o Mostly very short or behind the LOS passes. o Accuracy issues. o Doesn't see the field well. Commentators point this out several times, not that they're always right. o Bad reads. o Has good running ability: that one play where he was almost certainly sacked showed some great athleticism. That play in particular was interesting to me as it was his only completion of the 1st half over 2 or 3 yards. All others completed passes were at most 2 yards past the LOS or behind the LOS. Also, there were almost no mid/intermediate passes with the exception of the one over the middle which was at the turf/feet of Watkins I believe. He did throw 1 nice long ball to Goodwin on the right side deep, which was not caught, and another left side deep which was almost picked off had Watkins again I believe played a little DB. This is what I am seeing anyhow. Edited September 28, 2014 by San-O

With yards per attempt making Lewis look better than Manuel, and QBR making Manuel look better than Lewis, it was no longer clear to me which QB had had the statistically better season. (As an aside, Lewis's yards per attempt made him look like a solid backup/decent starter. His QBR made him look like chopped liver. Without knowing which statistical indicator was more valid, it was hard to form a firm opinion of the guy. This year's preseason, and the end of his time in Buffalo, pretty much resolved that dilemma.)
