Strangely enough he was in first All Nba team 4x in a row, which is a fantastic achievement for someone being under 25 years old, which just few others in Nba history achieved. How is this possible, if +/- clearly shows that he's not impactful player? Can non impactful player made 4x in a row first All Nba team?

If someone truly believes in +/-, conclusion should be simple, Luka is not even top 3 Mavs' player this season and not even top 100 Nba player. That's what +/- model is saying. Something works or something doesn't work.


I'm addressing these points because they are relevant to the broader discussion, but I will try to leave you alone after this Bob.

+/- stats in general are better served to identify outliers than they are the middle of the pack. The players who are so impactful, rather for positive or negative, that their presence seems to overwhelm the rest of the players in context can be identified with relatively small sample.

This is relevant in an MVP discussion because by definition, these are the players who should be overwhelming their teammates in a positive sense, and generally, that's what we see. Take a look at the top MVP candidates on the whole, you're going to see huge +/- numbers. And so where we see an MVP candidate where this is not the case, and has never been the case, there's something that needs to be identified that's keeping the player in question from showing up in these stats like most of the players seen as his peers are.

It should also be made clear that guys who have big +/- numbers in more limited roles are guys we need to be cautious of using that data for. If a coach is purposefully limiting a guy's minutes, for example, so that he gets to play with lineups that play to his strengths and cover his weaknesses, then +/- data for that player is biased in a positive direction. Doesn't mean everyone who plays in limited minutes is being helped in this way, but caution is advised. What I'd generally advise to a coach is that if a player is putting up huge +/- numbers in limited minutes, and the coach doesn't have a reason why he is avoiding playing the player in other contexts, he should give it a try. But if the coach knows why he's playing the player in one context but not another, then the player's +/- data is only telling us that the coach is probably being quite shrewd.

A lineup example of this is the classic Warrior death lineup with Draymond Green at the 5. Super-effective when it was used but Kerr used it in limited minutes. Maybe he was wrong to do so, but Kerr was also thinking about how effective it was as a change of pace. An opposing team that didn't scheme with the expectation of the Warriors playing a super-small lineup all the time could be exploited by a small lineup.

This also relates to approaches along the lines of what Nick Nurse and some other newer coaches do where what they want is to be able to continually change their on-court strategy over the course of a game so that the opponent can't get comfortable. It works in general so long as you've trained your players to be able to "play multiple" - change schemes and change roles in schemes - more adroitly than opponents.

Re: how could he make All-NBA if not impactful? 2 big things here:

1. All-NBA is just the opinions of people, and those people can be wrong. It's important as an analyst to understand how these people are coming to the conclusions they are, but once you understand that, if you're looking at some facet of the results that they don't understand as well, there's nothing all that concerning about disagreeing with them.

And yeah, there should be no hesitation in thinking that experienced posters in the analytics space might understand the data better than the official voters. That's just a known thing. The voters are absolutely getting better than they used to be, but historically you're largely talking about guys who are in the job they are in because they like sports and like to write, not because they have STEM expertise.

This also relates to why it took decades for the 3-point shot to be properly exploited. The people making the decisions historically, while they are knowledgeable about basketball culture norms, aren't the people you should expect to make data-based leaps.

2. As I've tried to be clear, I'm not saying Luka is not impactful, only that relative to the outliers who make up MVP ranks, he's doesn't measure up. It's certainly very impressive that he can handle as much of the playmaking burden as he can, and it's possible that having him play like this is the best way forward in terms of playoff resilience, but in terms of it resulting in huge on-court impact as a matter of course, we're 6 years in and we just haven't seen it.

Does that mean I wouldn't vote for him for All-NBA? No. I don't typically focus on stuff like All-NBA that much and would naturally see him as a bit weaker of a candidate compared to most because 1st team typically pits MVP candidates again each other, but it's not the case that there are typically 6 guards that look like MVP-level impact guys. Right now, for example, there's really just Shai and then a huge gap, so some non-MVP candidate guy would need to be placed on the 1st team, and it's possible Luka's as good of a candidate as any.

As I said, it's fine to bring up some things along these lines, but if all you're doing are finding reasons why the struggles of Luka's teams have nothing to do with Luka, you missing something essential.

Re: vice versa. If the facts were opposite, then the stuff I say about Shai, I'd say about Luka, and vice versa.

Is it possible Shai's situation is something that will turn out to be noise? Sure, not impossible.

Will this change anything about Luka situation? No. The only thing that will change the fact that Luka's never shown MVP levels of season impact is Luka showing just that.


1. I didn't hear any believable explanation, why SGA is in his 6 year suddenly become extremely impactful player either.

2. You're using stat that primarily reflects impact of lineups, but don't want to have conversation about those lineups? :lol:

3. I have to say I find it funny how you have extreme belief in very questionable stat, which at best seems having big problems in distinguishing between impact of the lineup and impact of a single player. And although you're saying that you're open for different evaluations of players, you in reality are not.

4. There's really nothing more to say, I will leave you alone with your strong beliefs.


1. I know I've already talked in this thread about a) Shai's shooting efficiency, b) Shai's turnover mitigation, and c) Shai's steals. These are all things that Shai is doing that have improved this year.

Beyond that, while we can have further discussion, I feel a need to emphasize again: You're trying to say that I cannot accept the data from this season unless I can explain it, while I'm trying to say you shouldn't reject data from this season unless you can explain why it should be rejected. It's not the same thing.

Perfectly fine for you to say that you're skeptical about Shai's growth in +/- this year until you've seen more sample, but you're looking to dismiss the stat entirely, which is just not a move that an analyst should ever look to be doing.

2. I'm all for talking about lineups, but from what I've seen you're mostly looking to use lineups from this year as a reason why Doncic doesn't look great with +/- stats while brushing aside the fact that this is just how things have always been with Luka for his entire NBA career.

Further, while I'm all for examining Shai's lineups in more detail, what I've already said is that the things I'd look for to indicate that his teammates are the impactful ones that supports such a conclusion. From what I see, you're trying to tear Shai's candidacy down on the basis of his teammates without lifting any of them up as actual rivals to Shai. Everything statistical about OKC this year that I see, whether box score or plus minus, is pointing to Shai being by far the most valuable player on that team.

3 & 4. So we keep talking past each other here. I'm keeping explaining to you how we make use of correlation and sample size to infer causal explanations in the the field of stats, and you keep coming back as if I haven't address the whole individual vs lineup thing when I very much have. You talk about me as having the closed mind, but conceptually you're just not understanding the basics of this stuff that has been part of the analytics discussion since long before you were on this site.

From what I can tell, you're just not really interested in the possibility that some of the things you think you know about statistical analysis aren't true, and so we're not going to get anywhere trying to discuss these finer points.


I'm just saying, if you want to use stats that are primarily describing what is going on with lineups, you at least have to pay attention about things that have huge impact on lineups. You're not overly interested to do so. (Luka's impact was always small, so no need for serious discussion, and SGA's impact, although being worse than Luka's first 5 years, was great in first 50 games, no need for understanding, how that huge jump is possible. And no, a little better TS% and more steals can't explain his jump in +/-). +/- might have some value, but only, if you thoroughly understand what is behind those numbers. The difference between SGA and Luka in +/- can't be explained with what we can see on the court for sure.

I explained that Luka has average career +/- because Mavs D was always bad. I presented you comparison with Steph, who was always bad defender, but had fantastic D around him until recently, which resulted in plunging +/-.

If I don't understand something, I try to see how data reacts in different situations. And +/- reacts very predictable, when we use it for evaluating lineups and totally unpredictable, when we use it for evaluating single players in different environments. Or better yet, we can easily predict in which environment will best players have great +/-.

Tell me, how will you defend +/-, if Luka makes sudden huge jump in +/- in year 7, playing exactly the same? Or in year 8? Or when he changes team? Seeing how +/- behaves, I guarantee you, he will have great +/-, when he plays for the top team.

+/- is nothing different from other basic or advanced stats. It can be used to help double check, reinforce, or verify something, but it is not the hill to die on. You put Rodman on a NCAA team and let that team compete in NBA, rodman would get his but the team would be blown away by total RBs. You can point out that KG never sniffed first round 8 years in a row and how the other top 30 players had done otherwise. Use the results to justify the point you want to make sometimes makes you sound invincible, and you can brush away all other evidences suggesting Rodman/KG was an impactful rebounder/player.

When we have the enormous amount of information, it is important to filter or make sense out of it. If X-ray at Denver airport kept giving an alarm that Shaq is an alien, 20x in a row, don't announce Shaq an alien but consider upgrade or fix your X-ray. There could be anomalies.

Why isn't Jayson Tatum getting more MVP buzz?? His team is miles ahead of Denver(7 less losses) and his numbers are great. He should be the leading MVP candidate and I'm a Denver fan.... I don't see how Jokic is winning this MVP unless Denver somehow climbs to #1 in the west.

He's getting buzz, he's listed 6th, but his team is too good to attribute all of the success to him, 4 all-NBA level players, 1 all-D level player, and 1 former all-D all-NBA player, and his stats are a notch below Jokic/SGA/Luka/Giannis.

I think we've reached the end of productive conversation to be honest, but I'll address the big thing as well as your last paragraph:

The big thing here is that you're focused on an idea of goodness which should be the same across all situations while I'm focused on value. To you, an indicator that a player's context makes him considerably more valuable is a sign that the indicator is flawed, where I just see that as how things work in team dynamics.

How will I defend +/- if Luka makes a huge jump in +/-? I don't think I will be defending +/- so much as I'll be jumping aboard Luka's MVP bandwagon, just like I've been expecting to do for years now.

Re: guarantee Luka will have great +/- when on top team. I'll just emphasize that to me "great +/-" is about the entire family of stats. If Luka is not able to stand out from his teammates by any version of the metric, then he won't be a "great +/-" in my assessment.

And the thing is, Luka's teammates in his Off minutes have already looked fundamentally solid for quite a while. The general rule of thumb is that for a star to lead a team to a title, you need a supporting cast that can tread water (neutral or better +/-) when he's off the court. And here's how the teammates of various guys in this MVP discussion have done in the minutes without him over their career:

Kawhi +3.3
Luka +0.6
Embiid -1.9
Giannis -2.5
Shai -2.5
Jokic -5.7

And then as a ground truth, the ultimate bad supporting cast situation was Garnett in Minny:
Minny KG -8.4

So this is the fundamental thing really: Luka's On numbers have looked worse than we'd expect, and his Off numbers have looked better than we'd expect basically for 6 years now. And so while you are trying to make arguments for why Luka would look better if only, you really also need to explaining why it is that Luka's teammates have actually looked a lot better than we'd expect if we were looking to use "But he has such bad teammates!" argument.

As always when I say this: I'm not saying that Luka has zero impact or that the team literally doesn't get any worse without him - stars play against the best opposing lineups after all - only that when we compare various MVP candidates who are all supposed to be in roughly the same boat carrying their teammates while facing the best the opponent can throw at them, Luka really hasn't had it rough.

So, forgetting about the actual buzz for a second and just looking to normalize for actual team success with a player, I'll repeat part of a stat I mentioned a few days back:

If an "OnWin" is the number of games a player had a positive +/-, here's how how the major MVP candidates stack up by that measure this year:

Jokic 40
Shai 39
Edwards 37
Giannis 36
Tatum 36
Kawhi 33
Luka 28

So you can see that the gap between the Celtics and everyone else is really about how well they do beyond what they're doing with Tatum on the court.

The top two MVP contenders by the Bontemps poll are also, by this simple measure, the top 2 MVP candidates based on how well their teams are doing on the court.

Incidentally, Tatum's actually looked better by this measure in the past. A similar polling of just MVP candidates by this metric in either '22-23 or '21-22 would have had Tatum on top. I didn't side with Tatum then, but I thought he was a serious candidate. This year by contrast, I see him as a bit weaker. Still quite possibly a Top 5 guy, but that's about it.

And I guess you believe off numbers more than how many games Mavs are actually winning with him and how many without him? ;)

So you can see that the gap between the Celtics and everyone else is really about how well they do beyond what they're doing with Tatum on the court.

The top two MVP contenders by the Bontemps poll are also, by this simple measure, the top 2 MVP candidates based on how well their teams are doing on the court.

Incidentally, Tatum's actually looked better by this measure in the past. A similar polling of just MVP candidates by this metric in either '22-23 or '21-22 would have had Tatum on top. I didn't side with Tatum then, but I thought he was a serious candidate. This year by contrast, I see him as a bit weaker. Still quite possibly a Top 5 guy, but that's about it.

I cannot take a metric seriously that has Edwards ranked 3rd. He is a good player don't get me wrong but I do not even believe he is more impactful than Gobert or possibly even Towns on his on team.

I'm just saying, if you want to use stats that are primarily describing what is going on with lineups, you at least have to pay attention about things that have huge impact on lineups. You're not overly interested to do so. (Luka's impact was always small, so no need for serious discussion, and SGA's impact, although being worse than Luka's first 5 years, was great in first 50 games, no need for understanding, how that huge jump is possible. And no, a little better TS% and more steals can't explain his jump in +/-). +/- might have some value, but only, if you thoroughly understand what is behind those numbers. The difference between SGA and Luka in +/- can't be explained with what we can see on the court for sure.

I explained that Luka has average career +/- because Mavs D was always bad. I presented you comparison with Steph, who was always bad defender, but had fantastic D around him until recently, which resulted in plunging +/-.

If I don't understand something, I try to see how data reacts in different situations. And +/- reacts very predictable, when we use it for evaluating lineups and totally unpredictable, when we use it for evaluating single players in different environments. Or better yet, we can easily predict in which environment will best players have great +/-.

Tell me, how will you defend +/-, if Luka makes sudden huge jump in +/- in year 7, playing exactly the same? Or in year 8? Or when he changes team? Seeing how +/- behaves, I guarantee you, he will have great +/-, when he plays for the top team.


I think we've reached the end of productive conversation to be honest, but I'll address the big thing as well as your last paragraph:

The big thing here is that you're focused on an idea of goodness which should be the same across all situations while I'm focused on value. To you, an indicator that a player's context makes him considerably more valuable is a sign that the indicator is flawed, where I just see that as how things work in team dynamics.

How will I defend +/- if Luka makes a huge jump in +/-? I don't think I will be defending +/- so much as I'll be jumping aboard Luka's MVP bandwagon, just like I've been expecting to do for years now.

Re: guarantee Luka will have great +/- when on top team. I'll just emphasize that to me "great +/-" is about the entire family of stats. If Luka is not able to stand out from his teammates by any version of the metric, then he won't be a "great +/-" in my assessment.

And the thing is, Luka's teammates in his Off minutes have already looked fundamentally solid for quite a while. The general rule of thumb is that for a star to lead a team to a title, you need a supporting cast that can tread water (neutral or better +/-) when he's off the court. And here's how the teammates of various guys in this MVP discussion have done in the minutes without him over their career:

Kawhi +3.3
Luka +0.6
Embiid -1.9
Giannis -2.5
Shai -2.5
Jokic -5.7

And then as a ground truth, the ultimate bad supporting cast situation was Garnett in Minny:
Minny KG -8.4

So this is the fundamental thing really: Luka's On numbers have looked worse than we'd expect, and his Off numbers have looked better than we'd expect basically for 6 years now. And so while you are trying to make arguments for why Luka would look better if only, you really also need to explaining why it is that Luka's teammates have actually looked a lot better than we'd expect if we were looking to use "But he has such bad teammates!" argument.

As always when I say this: I'm not saying that Luka has zero impact or that the team literally doesn't get any worse without him - stars play against the best opposing lineups after all - only that when we compare various MVP candidates who are all supposed to be in roughly the same boat carrying their teammates while facing the best the opponent can throw at them, Luka really hasn't had it rough.


And I guess you believe off numbers more than how many games Mavs are actually winning with him and how many without him? ;)


As I've pointed out, you're trying to use a different stat where Luka looks more impactful to prove that it's wrong to say he's "unimpactful", but aside from the fact that I'm not saying he's "unimpactful", you're never taking these stats and applying them to all the other candidates in any kind of thorough manner. You're looking to stop as soon as you find something that tells you the story you want to believe.

So, forgetting about the actual buzz for a second and just looking to normalize for actual team success with a player, I'll repeat part of a stat I mentioned a few days back:

If an "OnWin" is the number of games a player had a positive +/-, here's how how the major MVP candidates stack up by that measure this year:

Jokic 40
Shai 39
Edwards 37
Giannis 36
Tatum 36
Kawhi 33
Luka 28

As always: I don't use these simple metrics to be the end-all be-all but rather to give data that can easily be understood by anyone.

I was responding to someone who felt like Tatum being the star of the best team gave him a huge leg up...but this metric shows us that despite his team being the best, the teams of other players - who happen to be more serious MVP candidates in the eyes of the Bontemps poll - have actually in some ways been better with those players than the Celtics have been with Tatum.

Re: Edwards, Gobert & KAT. Only reason I just listed Edwards honestly is that he's the one getting traction as the MVP candidate of Minnesota. To just list out Minny's leaders here - while putting a 24 minute minimum to cull role players:

Edwards 37
Gobert 37
KAT 34

So yeah, if you want to argue for Gobert as the MVP of the Timberwolves, this simple metric isn't actually arguing against you.

I will say though, to be honest, it's hard for me to understand anyone being skeptical about a stat because KAT doesn't look that great in it. I think by this point we know that KAT is a really flawed player to rely upon.

I explained to you at beginning, I don't believe in +/- as measure of impact of a single player. Stat behaves completely erratic in single games and single games are data that is used for it. I didn't see a single prove that we should take +/- seriously.

You're telling me that his off numbers suggest that Mavs without him are playing equally good, so they should have won similar amount of games, but somehow Mavs are winning a lot more with him. How can that kind of data help us, if it's completely false?

I understand very well how statistical analysis works. I'm not talking about noise in small sample sizes. I'm talking about bad data. Noise is in the small sample sizes for the impact of the lineups, and it's true we're getting pretty realistic numbers with bigger sample size, for the impact of the lineup. And that's why all the best lineups are having very good and very similar numbers. But we're getting absolutely bad data for describing the impact of a single player. You can play bad, average or good, your +/- will be very good, if you're part of the winning lineup. And you can play good, average or bad and your numbers will be bad, if you're part of the losing lineup.

Wemby is averaging 20/10, is the the best in league in blocks, but his on court +/- is - 6. Change Chet with him and he would have had + 10 in OKC. So tell me, what impact is his -6 measuring? His or starting lineup of Spurs? How that data helps to evaluate Wemby? Is Chet generational player and Wemby just average rookie?

I'm not ignoring the data, because it doesn't suit me, I ignoring the data because it simply doesn't have any relevance, because it's measuring different things, not impact of the single player.

Am I missing something or is Luka's unadjusted on/off numbers not that weird. His team has been when he's on the court in non-garbage time minutes. His team is -3 in the minutes when he's off the court https://www.pbpstats.com/wowy-combos/nba?TeamId=1610612742&Season=2023-24,2022-23&SeasonType=All&PlayerIds=1629029&Leverage=Medium,High,VeryHigh. His Time-Decay RAPM is definitely disappointing (where he's 79th), but his long term RAPM doesn't look that weird where he's +4.8 on offense and +0.7 on defense (higher numbers are worse on defense).

You're calling it bad data because it's about lineups rather than players, but that type of separation is what the field of statistics works with. It's why we talk about sample size, correlation & causation.

Re: +/- will be good if you're in a good lineup. Okay to emphasize again:

You're talking only about raw +/-, while I'm talking about the set of different stats that can be created using those raw ingredients, which includes, for example, the on/off data that I've shared with you a number of times, and you've literally responded to trying to discredit with other techniques.

We're clearly going in circles.

Re: Wemby vs Holmgren. I don't think it's at all clear how well Wemby would do in Holmgren's place - it's a great question to discuss sincerely though - though I will point out that Wemby has a positive on/off, which again, you've already had explained to you, and you've already looked to reject.

Simply a question of whether the data looks like that of an MVP candidate.

Can you explain -6 by Wemby? You can use whatever adjustment you want, regression...

I understand very well how statistical analysis works. I'm not talking about noise in small sample sizes. I'm talking about bad data. Noise is in the small sample sizes for the impact of the lineups, and it's true we're getting pretty realistic numbers with bigger sample size, for the impact of the lineup. And that's why all the best lineups are having very good and very similar numbers. But we're getting absolutely bad data for describing the impact of a single player. You can play bad, average or good, your +/- will be very good, if you're part of the winning lineup. And you can play good, average or bad and your numbers will be bad, if you're part of the losing lineup.

Wemby is averaging 20/10, is the best in league in blocks and his on court +/- is - 6. Change Chet with him and he would have had + 10 in OKC. So tell me, what impact is his -6 measuring? His or starting lineup of Spurs? How that data helps to evaluate Wemby? Is Chet generational player and Wemby just average rookie?

I'm not ignoring the data, because it doesn't suit me, I ignoring the data because it simply doesn't have any relevance, because it's measuring different things, not impact of the single player.


You're calling it bad data because it's about lineups rather than players, but that type of separation is what the field of statistics works with. It's why we talk about sample size, correlation & causation.

Re: +/- will be good if you're in a good lineup. Okay to emphasize again:

You're talking only about raw +/-, while I'm talking about the set of different stats that can be created using those raw ingredients, which includes, for example, the on/off data that I've shared with you a number of times, and you've literally responded to trying to discredit with other techniques.

We're clearly going in circles.

Re: Wemby vs Holmgren. I don't think it's at all clear how well Wemby would do in Holmgren's place - it's a great question to discuss sincerely though - though I will point out that Wemby has a positive on/off, which again, you've already had explained to you, and you've already looked to reject.


Can you explain -6 by Wemby? You can use whatever adjustment you want, regression...


And when you at it, you might use all available statistical methods to explain how Dame is + 6.5 on court and +10 on/off and Luka only +2.8/+4.5. Below is head2head

Luka being light years better in everything except FT%. The difference been them in counting stats, efficiency and advanced stats is brutal. But somehow +/- is saying that Dame is much better player on court and on/off.

Well, I'll give it a shot.

- The Spurs are getting outscored with Wemby on the floor over the course of the year - they are also getting outscored even worse with Wemby on the bench.
- Wemby appears to be showing on/off impact on defense, and the Spurs are really only poor on offense with him on the court - and they are bad without him too.

So, number one thing I'm emphasizing here is that it's not really clear at all that Wemby is being unimpactful, only that whatever impact he is having, it hasn't been enough.

The bigger concern is offense, and this is no surprise really: It was Wemby's defense that was always the more impressive thing as a prospect. Greater and greater length helps with shotblocking more than it does with shot-making.

In general in fact the most valuable offensive players are typically guys who can be valuable from the offensive perimeter, because those who cannot must receive the ball close to the basket in order to do their thing, and the defense knows this and can disrupt the offense by making it harder to get that player the ball. Wemby of course has been practicing his 3-point shooting but at this point he's literally not good at it.

Now as I say all of this, this is also where having a great point guard can help in getting the interior guy the ball. The Spurs began the year with some strange choices before adjusting, and he does look better recently - talking box score here, not just +/- - and this naturally leads to a conversation again about stats changing when context changes.

If Wemby is capable of being an efficient volume scorer if he had a quality point guard, then it's understandable to think of that as the "true level" of Wemby, but from a value-added perspective, that's only value he can add with such a point guard and shouldn't be credited with this value if he's not able to add it.

And of course by that same token, a point guard capable of making use of an interior scorer may well not add much value on a team without such an interior scorer. It's in the synergy between the two players that the value resides.

Over to Holmgren:

I think I notice is that Holmgren has a much higher 3P% than Wemby but is also even more likely to be assisted on those 3's. In general, this is the sort of thing where we sometimes link this to how much help a player has. We should be careful there though. I would suggest that Wemby simply should not be taking 3 non-catch&shoot 3's in terms of what's best for his team right now. It might be for the best in terms of Wemby's future development, but right now, it's not valuable. This is also noteworthy given that with Wemby's height, there's really never a time where he'll get the ball in a 3-point shot location but need to dribble to get more open.

I think this speaks to a difference that goes beyond quality of supporting cast:

Holmgren is being asked to fit in on a contending team where Shai is the offensive star.
Wemby is being encouraged to try things out and see what he can do.

Given these approaches, it's very possible that Holmgren plays in a more valuable style even if he's not more capable of value in the abstract.

This makes it an interesting conversation in terms of who more deserves the ROY, but just from a direct value-add perspective, it makes it more likely that Holmgren will come out on top in the short-term.
