QBR is a formula, just like the original "Quarterback Rating". The specific formula isn't disclosed, though, so it is anyone's guess exactly what the variables and calculations are. The problem that the OP is complaining about is the fact that QBR doesn't take into account how heavily the offense relies on the QB who is being evaluated. A backup QB can come into the game late during a blowout victory, complete a few easy throws, and leave the game with a higher QBR than either starting quarterback. It only attempts to evaluate how well the QB performed in the plays that he was involved in. That being said, even if you accept the fact that QBR has built-in limitations, it still seems to do a pretty horrible job.
Gotcha, I thought when it was first coming on they explained that they watched every play and assigned as number to each variable with the formula. Thanks for the explanation bud.
QBR is just completely hilarious because they refuse to disclose the formula. If they did, criticisms and suggestions for improvement could be made. As it is, anyone who even remotely follows the NFL can tell it's one of the worst rating systems ever created. What else do you need? But ESPN insists on touting it all over their website as if it's relevant.
Any rating system that makes Sanchez look like he played good or great or better is a farce and should be discounted... U dihnt knew?
IF a QB threw 3 passes all for TD's and another QB threw 45 Passes with 1 td and 2 picks who had the better effect on the team and game? QBR is BS but lets not fall in love with Yards passing for a qb bcuz a screen can net 90+ yards, ask E. Manning and V. Cruz. Making throws that count, thats throws in the RZ, that has been the money zone for Sanchez, and one thing he has excelled at I beleive.
QBR measures a QB's decision making process. For example, Mark had to decide whether to use his left hand or right hand when handing off to Greene all day.
You can't effectively "rate" a QB. Stats don't tell the whole story, and while breaking it down to a play by play basis is good in theory, it becomes very opinionated. From a statistical stand point the most important stats in my opinon are, INT %, 3rd down passing (1st down %), Red Zone efficiency and 4th Quarter passing when down by 10 or less or up by 7 or less. But even those don't tell the whole story.
the best measures to me are YPA and turnover ratio (how often a QB turns it over). It's a very good way to take a snapshot with just two stats, and it's far better than using QBR.
Sanchez could have had exactly the same numbers he had and if the Jets lost the game I guarantee his QBR wouldn't have wound up where it did. The thing is too subjective. It relies on interpretation by viewers after the fact and that interpretation is the root of the problem. The reviewers are going to be positively inclined towards a QB whose team won and negatively towards a QB whose team lost. They're going to have eyeball issues based on their predisposition at the time they review the plays. If ESPN really wants to take a stab at making this thing work they need to isolate their reviewers from the games and the scores as they happen and then feed them individual plays out of sequence with only the down and distance known as the play is being reviewed. They need a double-blind review system.
I don't think Shonn Greene factors into QBR. Remember, Sanchez had a higher QBR against the Bills when he threw 3 TDs. He only threw 2 in this game and had no turnovers and completed 60%. I'm sure that all factors in. Sanchez had a solid game, hence the good QBR number.
the problem is the average fan thinks a QB needs to throw for 300-400 yds to have a good game. Sanchez didn't need to do much but whwn called upon he made some nice throws converting big 3rd downs in the 1st half.
Bingo. People only look for negatives, hence the ONE "negative" stat he had that game, 80 yards. People will think it automatically means he played bad. But again most fans are simpletons.
Of course Sanchez didn't play badly against the Colts. He was effective with what they asked him to do. But, at the same time, I really don't think it mattered too much WHO was out there at QB this past Sunday. That shouldn't necessarily be a knock on Sanchez, though.
The average fan knows that Sanchez wasn't exactly instrumental in this win, either. If they watched the game, they know that Sanchez made a few plays. Sanchez also DIDN'T convert a few third downs too, one inside his own ten yardline on the Jets' first drive, which resulted in an Indy fieldgoal after the punt and the Colts' only lead of the day. This is Sanchez's type of game totally. He operates well when the defense and run game are clicking. He's a system quarterback, and an effective game manager when the rest of the team is playing well. He threw for a couple of TDs and made a few throws...didn't make mistakes, which was probably his most important contribution. He played well given his duties in that game, sure...but you gotta watch how much credit you give him in a game like this, where it wasn't even a contest for very long. And I don't think you give the "average fan" (whatever that's supposed to mean) enough credit. Anybody that watched that game could see that Sanchez played well for the most part with what they asked him to do.
ESPN's QBR is one of the most useless and worthless stat ever invented by human beings. Quarterback rating (actually, Quarterback rating DIFFERENTIAL) already is an extremely accurate predictor of how the QB (and the offense, by the same token) will function. No fluffs, no gadgets. Just cold hard facts.
You haven't seen Alex Smith play. Sanchez has come from behind to win games. He can do it if he has good enough of supporting casts. He has done it a few times in his short career already. (You cannot say Jets did their best to bring Sanchez protections and weapons, can you? I know Jets did not do that, if that means anything to you.) Ok. Sure. I am no Sanchez homer. But to call him a 'system quarterback' that will only do well when other things click is flat out wrong.
First of all, I have seen Alex Smith play numerous times, and that has nothing to do with Sanchez. I've also seen Sanchez's come from behind victories. If you look at those in say 2010, you'll see that Santonio Holmes caught short passes on critical plays and turned them into game-changers at the end a lot more than Sanchez did. And who put "Sanchez" in the position to come from behind and win these games all on his lonesome? Nobody? Sanchez IS a system QB, and he depends on defense and the running game to even put him in position to pull one out at the end, which he has contributed to in the past. Yeah, Sanchez has made plays in critical situations, but he also hasn't. Fact is that he is LUCKY to have the opportunity to be put in those situations based on the play of the rest of the team...and they are mainly close games, not ones where Sanchez imposes his own will for any sustained period of time, which is the mark of a great quarterback. I think you may in fact be a Sanchez homer. "We won the game, so Sanchez must be good."
There are QBs that CANNOT DO THAT, given the same opportunity. Sanchez is not one of them, obviously; that's what Alex Smith reference was aimed at. (Maybe you were too obtuse to get that - for that I apologize.)
