Not a given in general, but in regards to duncan, who posts net-rating splits that top even magic for his prime and with lineup-adjustments looks like the 2nd or 3rd most valuable player of the last near 30-years, and who we've seen this effect before with other teammates, I'd say it's rather likely. Perhaps 2005 is an exception, perhaps not.
Hmm. So I think there's a point along these lines that makes sense to me:
If a superstar who plays big minutes puts up huge RAPM, and he has a teammate who plays less minutes and puts up a bigger On/Off with a smaller RAPM, the most likely explanation is that that the big minute guy is playing on average with weaker lineups around him.
On that note, if a player's impact also happens to look bigger when you take him out of a team entirely then the rapm or the on/off, there's a good chance both of those metrics are sleeping on his actual value though as always you have to be careful with context and about sample-size
Duncan has the uniquely(and i really do mean unique) lopsided minute distributions, the big rapm, and a indirect/wowy portfolio with the last bit maybe gesturing at mount rushmore case(and rapm not really dismissing the possibility) to go with proof of concept with different systems and different teammates.
Lots of reason to consider any on/off discrepancies a product of noise rather than a reflection of his actual value, though again, the 2005 --playoffs-- might be an exception.
I'm confused about the "when you take him out of a team" point. I thought we already went through this and saw that while the team missed Duncan more when he didn't play a game during the regular season, the data favors Ginobili in the playoffs.
And yes, 2005 is clearly different in general, and I think folks should really consider how they'd think about the situation if the Spurs had fizzled out in the playoffs, because it's really what we should expect to happen if Duncan was the sole outlier talent on the club.

Add it all up and you get

300Make of that what you will.
Okay, so if I'm reading what you said right, you're talking about '04-05 playoff minutes.
Rasho played 38 minutes in the playoffs with Ginobili and without Duncan.
Rasho played 12 minutes in the playoffs with Duncan and without Ginobili.
I was talking before about regular season, so let me put what that looks like:
Rasho played 499 minutes in the regular season with Ginobili and without Duncan.
Rasho played 267 minutes in the regular season with Duncan and without Ginobili.
I'd say it's analogous to a point, except that the playoffs are a lot smaller. Some of that could be expected just from the playoffs being a shorter season, but it also has to do with:
Yeah, I missed "regular season" though, as has been pointed out before, we got large samples of the spurs without both, and it was duncan they struggled without.
I don't know what the minute distributions for all the bad teammates is, but when a team does just fine without you for substantial samples, the on/off(at least for the rs) saying otherwise is probably noise(barring major team context).
Look what's undeniable is that both Duncan & Ginobili are outliers by +/- indicators throughout their career. I understand that the conversation we're having can't help but have a lot of Duncan vs Ginobili going on, but I'm not trying to say Ginobili should be ranked higher in general than Duncan.
I'll admit I'm using the context of the thread to discuss the '04-05 playoffs which is a very specific moment over the course of their careers where I see Ginobili as the team's MVP, and when we talk about just that type a sample it makes sense to think about noise...but we know what the career data tells us too, and it tells us that no-doubt-about-it-superstar Duncan had a teammate who also put up huge impact indicators as a matter of course.
This then to say that trying to use "probably noise" to explain things away here just doesn't make sense to me.

Rasho played 7.6 MPG in the playoffs.
So I think a likely explanation here is that as Pop trimmed the fat in the playoffs, that meant that there was less time to be played with "bad" teammates, and so players who spent the regular season playing a bigger fraction with the "bad" are going to play with better teammates in the playoffs.
With this in mind, it makes sense to say that a guy like Ginobili might look better by On-Off in the playoffs compared to the regular season.
This doesn't explain Ginobili's general RAPM improvement in the playoffs, nor the stark difference between he and Duncan in the 2005 post-season, but it's something to look for as part of a general trend as coach's shorten their rotations.
i mean rapm isn't impervious to those effects, though i would be curious what the 5-year comparison looks like during the stretch you have many penned as a potential 5-peat centerpiece. As i highlighted when i did the cheema break-down, with the exception of Lebron James, everyone who played 200,000+ regular season possessions or 20000 playoff possessions saw a drop for their career marks in the postseason. Though maybe you are referring to something else?
When you refer "isn't impervious to those effects", do you mean RAPM has collinearity issues too?
If so, that's certainly true, but if you're looking to reject all the data we have that can be used to show playoff impact (raw +/-, W-L with/without you, RAPM) it feel like there's nothing left but the regular season default.
Always fine to say "I'm not confident enough in the sample to weigh it significantly", but when you're saying stuff like "probably noise", that's a very different slant in my eyes.
Re: referring to something else? Honestly I was just going by memory from looking at stuff previously.
But if we use Cheema's
25-year post-season study, we can see that there are plenty of guys with a bigger postseason RAPM compared to regular season, and that Ginobili is one of them.
To just list Duncan & Ginobili here:
Duncan: RS: 4.592, PS: 4.289, Diff: -0.303
Ginobili: RS: 3.724, PS: 5.169, Diff: +1.445
Gionbili has 23,031 postseason possessions listed btw, so I think he should qualify based on your stated thresholds, though I must say that I'm not particularly concerned about that threshold. Small sample is always a problem, I don't think we need to get to 20K of something before we have a sample worth considering.

Someone who spends a decent amount of time with bench players is basically by definition playing with worse teammates, but if he can feast against inferior opponents well enough, his +/- data will be inflated.
But as I've said, thing is such a role would predict that come playoff time such a player would either be less impactful or play less minutes or both. And Ginobili's indicators go 180 degrees in the opposite direction.
I don't think it's entirely that, but yes that is a potential factor to. In soccer you will get supersubs who fans clamor for to get more minutes but they are specifically deployed in favorable situations for them to produce and often see that per 90 peroduction drop if they're moved into the eleven.
I don't know how much that is a factor here though
Sounds like what you're talking about is the ability to sprint rather than run a marathon.
In baseball, closers are guys who often just pitch for a single inning to finish the game, and they basically hold nothing in reserve. They couldn't pitch a whole game like that, and so it's not an apples-to-apples conversation when comparing them with other pitchers.
I think it's reasonable to ask about particular players only being able to play like they do because their minutes are limited. The classic guy I think of like this is Bobby Jones back in the '70s. Ginobili is possibly the best known example from his era, but you could also look at guys like Nate McMillan from the '90s or Alex Caruso today.
I believe that the question should be considered for all of them, but also that they are all also different guys with different bodies.
Well, it's also about being deployed situationally in favorable situations for you to perform as opposed to simply being deployed regardless.
Right, which is certainly something I've already spoken to in this thread. If you'd like to make the case that Ginobili's minutes were being cherry-picked based on the opponents in the game, go right ahead, but while I think the question is a good one to consider, I don't think that's what was happening with Ginobili, and in general I don't think that's what's happening with guys who are playing more On than Off.
