Misused is probably the wrong term, but there is an unavoidable difference in usage that certainly factored int the difference we saw. Im curious to see what happens when we get there.

There are some funky results (e.g., Pippen at 11, Bird at 15, etc), but I think it's pretty reasonable overall (I'll probably keep working on it and I'd welcome any suggestions for improvement).

The result for each season is found by polynomial regression:

titles ~ impact + impact^2

where impact = each player's season estimated impact adjusted for expected playoff difference

and titles = a binary variable indicating whether or not the player was a 25+ mpg player on a title team (1 if he was, 0 if he wasn't)

Then I sum up the expected titles for the player's career.


I'll probably also post all the playoff adjusted net ratings and if people are interested I can post the average playoff difference for each player.

Oh wow you did use my suggestion.

So why is Pippen so high now? What's the playoff difference like? That hurts Robinson, but he's still top ten.

actually usage is one of the myths. If you look at the numbers(and remember watching Dallas from 01-04) its clear Nash wasnt under-used in Dallas. The biggest factor by far in the change from Nash in Dallas to Nash in Phoenix, is shockingly enough---Steve Nash. That and the Suns players were more symbiotic with him than Dirk in particular, but also the rest of the Mavs team.

But this idea that Nellie underused Steve Nash is flat incorrect, and when you stop to even just think about it, how did the notion ever get started that Nellie didn't know how to use him? It's crazy. Nope credit should go to Steve for the complete turnaround in how he took care of his body.

Again I'm not trying to get too far down this road right now, but it wasnt lack of opportunity that made Nash in Dallas not quite the player he became in Phoenix. Nash was a great RS PG by the end of his days in Dallas. It was the playoffs where most of his struggles came and much of that was conditioning-related imo.

Case in point: Hakeem's usage and assist rate climbed in the mid-90's. edit: The point isn't about Nash, so let's not go there. There are plenty of players in NBA history who were a bit misused for part of their career. And as I said, I don't think it's simply how he was used and he's at fault too.

This is all nitpicking, but this is for picking him over Larry Bird.

Re: RealGM Top 100 List #9 -- Bird v. Hakeem 

Post#247 » by magicmerl » Mon Jul 21, 2014 10:32 pm

My vote is for Hakeem.

Here's how they look on a per-100 possession basis in the regular season, ordered by offense-defense:

Code: Select all

Player.. PTS  REB   AST STL BLK TOV PF  TS%  USG% ORtg DRtg OWS   DWS  WS    WS/48
Bird.... 30.3 12.5  7.9 2.2 1.0 3.9 3.2 .564 26.5 115  101   86.8 59.0 145.8 .203
Hakeem.. 30.3 15.5  3.4 2.4 4.3 4.1 4.9 .553 27.1 108   98   68.3 94.5 162.8 .177


And in the playoffs:

Code: Select all

Player.. PTS  REB  AST  STL BLK TOV PF   TS% USG% ORtg DRtg OWS  DWS  WS   WS/48
Bird.... 28.0 12.1  7.6 2.1 1.0 3.6 3.3 .551 24.8 114  104  13.8 11.1 24.8 .173
Hakeem.. 33.7 14.6  4.1 2.2 4.2 3.8 5.0 .569 28.9 112  101  11.9 10.7 22.6 .189


I actually started writing this up as a post in support of Bird, since there's a pleasing symmetry in having him next to Magic in the rankings. But the numbers above don't make Bird look better than Hakeem, other than assists.

Hakeem has the edge in scoring and rebounding as a playoff performer, as well as a slightly higher WS/48. He produced more win shares in his career, which is the longevity angle, or lack thereof on Bird's part. I still struggle with how (relatively) poor Hakeem was in the regular season, I don't understand why he *increased* his production in the playoffs against better competition. Ultimately I don't hold the fact that Hakeem didn't have as many deep playoff runs than Larry did against Hakeem, since i think that's more a function of team quality than the individual player.

I will vote for Hakeem, he has the edge in longevity and he is the better playoff performer without a shadow of a doubt, their peaks are a wash IMO.

If you are interested in joining our voting panel, post for a few threads with good analysis and I will add you.

With virtually no support for a 3rd party candidate, can we call the loser here #10, and move to 11.

19 non winner initial votes - 33 total, 17 is majority

Hakeem/Bird Loser would need 3 votes of 14 to not have runoff. That's 21%, and they each have over 40%.

We have talked a lot about Hakeem and Bird, and think it would be best to move along after the run-off.

No, you should judge players based on their skillsets (their "goodness"), how easy those skills are to apply to a team situation, and how much you can elevate various team environments. Otherwise, why is anyone mentioning Kevin Garnett at this point?

And if players shouldn't be punished for bad teammates...they shouldn't be punished for bad coaching either.

The career that Hakeem Olajuwon actually had was a pretty fantastic one, where his pre-93 seasons were still fantastic, just not applied in a proper team context, because Don Chaney was kind of dumb and his teammates were coked out and inconsistent. And yeah, he made improvements as a player...but he was still a pretty fantastic player before then (pre-93 Olajuwon was basically on the same level as prime KG and prime Duncan...he was always a much more naturally gifted scorer, but he didn't read defenses the way they did...his defense was always on their level though).


So what we're seeing here are two different philosophies:

1. Rank based on what they actually did.
2. Rank based on an idea of they "would" have done.

The second philosophy itself can be broken up into many variants. I've always been pretty tolerant of it as long as it didn't ignore something a player did against himself based on mental immaturity/weakness/etc.

I personally tend to stick to a model that starts focused on (1), and only factors (2) in as a kind of sanity check. This doesn't make for the most consistent possible model, but it allows me to have something pretty consistent that if it has any inconsistency is based on something I feel strongly about.

Interestingly enough, you're mentioning Garnett here as if that has to be based on what he "would" have done, and that isn't how I see it at all. The most objective stats we have for player's actual impact say Garnett had extreme impact for a very, very long time. That alone puts him in contention not only at this point, but earlier.

The fact that Garnett's ALSO more portable than perhaps any other player we've ever seen though, does make his case even stronger.

When we speak of the what "would" have happened, there are players who would be helped if I went more in that direction.

Nash's longevity as a superstar jumps if teams simply understand him earlier.
Magic's longevity as a superstar jumps if he's simply allowed to play.
Bird's longevity as a superstar may very well have jumped if not for an injury he sustained doing manual labor in French Lick, which had nothing to do with basketball.
Wilt's longevity as a superstar jumps if he simply prioritizes helping his teams play basketball better.

The last one is the only one that I really have trouble accepting. Anything else is fair game to me, as long as people can stay consistent and really argue effectively for their thinking. The reason I refrain from going too far in this direction is because I'm skeptical I can do that. And I say this as a kind of connoisseur of ranking things, I've done it compulsively since I was a kid and literally been algorithmist for a ranking website: Sometimes I pick the more conservative approach because I know I can get something meaningful out of it, even if it's not something I call perfect.

Not saying anyone else has to, but it's basically a given that if part way through a ranking project you decide you don't know how to continue in line with what you've been doing, you're far more likely to quit and never refer back to the results again.

I'm glad someone brought this up, because I'd like to shoot it down before it gets momentum.

Looking at the list of pre-lists people sent me, whichever of Bird or Hakeem gets voted in, 8 out of 11 people would not have the other one next.

For a variety of reasons a thread like this can make it seem like basically everyone thinks 2 guys are the clear next two guys, but they don't actually.

Post#252 » by acrossthecourt » Mon Jul 21, 2014 10:55 pm

Using that ASPM from earlier, here's the difference between Bird's best seasons and Olajuwon's:
0.769 (this means Bird's season is more valuable)
1.158
0.883
1.035
0.631
0.346
0.397

People scoff at a difference of 0.3 to 1, but at a high level that's pretty striking. You can see this in ElGee's title odds from earlier. There's not a linear relationship here. Seasons of +7.7 and +7.2 are huge, and I've been going on peak seasons, some sustained excellence of like five years.

Not that ASPM is perfect. But Olajuwon is a stat-stuffer (in a good way with those steals and blocks) so I don't think it's entirely unfair, and it aligns with how I see them. Bird has the advantage from seasons ranked 1st through 7th, and Olajuwon 8th through 12th plus a few lower quality seasons like his weird Toronto stint. I guess it depends on what you're looking at, and how you actually judge them, but I think those ultra-high seasons are a lot more valuable than summing the ones ranked like 8th through 15th.

Fantastic player, and honestly, as much as I like LeBron...LeBron vs Bird is a LEGITIMATE debate for me as far as peak vs peak, and I didn't used to think that way before this project (I had LeBron as the #3 peak prior to the project fwiw...Jordan and Shaq at #1 and #2...those were a clear top 3 for me...but now Bird and LeBron are a toss-up for #3 imo).

But his longevity is just weak compared to someone like KG, as well as Hakeem. 80-88 + 90 is 10 years where he's a super-high impact player. But injuries hamper all of these years. His 90 season in general is a clear step below his first 9 years. His 80 playoffs are marred by the fact that he runs out of gas by the time he hits the playoffs. His 83 playoffs are marred by the flu. His 85 playoffs are marred by a broken hand he suffered during the Finals. His 88 playoffs are marred by bone spurs. He was still a great player in the face of all of these ailments, but was he a better player than a healthy, prime KG? I don't think so.

And on top of that, KG has 10 years of being a super-high impact player imo (99-08), as well as a few AS-caliber seasons in addition to that (97, 98, and 10-13). That's 16 years vs Bird's 10 years.

TBH, I think I would take Karl Malone over Bird as well. Again, has nothing to do with prime Bird, who I think is a top 3-4 player in the history of the game...has everything to do with the fact that prime Bird just wasn't around very long, and when he was, he was still hampered by circumstances that reduced his impact. Injuries really didn't affect Hakeem, KG, or K. Malone all that much (they may have in a couple of instances here and there, but nothing major really comes to mind...10 for KG probably, who was visibly injured throughout the season following his knee injury in 09).

So I don't have Bird coming up until after Hakeem, KG, and K. Malone are in. There are a few other players that could maybe be argued over Bird as well (Oscar, West, and Erving come to mind).



If KG or Hakeem played as hard or as well as Bird would they also have all those injuries that reduced their career.

Its a quality over quantity argument.

Once KG and Hakeem had 2 Finals appearances they began to get injured and slowed down. Bird was reaching the Finals much more often. If KG had been traded a few yrs earlier he most likely would have become 2014 KG a few yrs earlier.


I would much rather have the best player in the NBA for 5 or 6 season than a top 10 player in the NBA and for 10 to 12 seasons.

With all the talk about Hakeem's struggles against the Sonics from 93-96 I decided to look at Hakeem's RS FG% vs Sonics compared to his teammates and the league average. As shown in the table below, Hakeem consistently shot above league average, while his teammates were shooting well below the league average.

93-96 Rockets RS FG% vs. Sonics

Code: Select all

Season    Hakeem’s FG%    Teammates FG%      League Avg. FG%

93          .480                    .422                  .473

94          .686                    .408                  .466

95          .481                    .429                  .466

96          .571                    .396                  .462

We had a similar argument about Duncan and KG and the increased impact of having deep post season runs on your longevity. Every year that you play deep in the post season, it puts a bigger toll on your body, and you have less of the offseason to recover for next year. Guys like Duncan, Bird and Magic played well into the summer for the majority of their careers. For a guy like KG who for most of his career had first round eliminations, or didnt make the playoffs at all, it's hard to compare his longevity to guys who had deep playoffs runs from the very beggining of their career onwards. People try to state that KG played a lot of regular season minutes, but In reality regular season games don't force you to play till June, and also don't force you to play series under playoff intensity. And every regular season game doesn't subtract from the time you have to recover for next season, which puts your body at greater risk

This is a common thought--and it's of course tied directly to his highly versatile game. But what's interesting to me is that Dirk played in the same era and while he never left Dallas, he played for a minimum of 3 distinct teams: Nellie/Nash, Avery, and Carlisle/Kidd and was hugely successful both individually and from a team standpoint with all of them. Maybe KG could be as portable, but Dirk actually proved it. 05-07 suggest that his portability from a team standpoint has some limits. Dirk's teams in that same period while better constructed aren't actually much more talented and Avery Johnson is one of the worst coaches of all-time so that's not an edge either.

And there are other players as well who have proven more portable than KG. We need to be careful not to assume versatile=portable and that less versatile players automatically aren't.

For those interested, I updated my expected titles metric with playoff information (I'm posting this here because I think it can be somewhat helpful to the project):

http://shutupandjam.net/nba-ncaa-stats/career-estimated-impact/

There are some funky results (e.g., Pippen at 11, Bird at 15, etc), but I think it's pretty reasonable overall (I'll probably keep working on it and I'd welcome any suggestions for improvement).

The result for each season is found by polynomial regression:

titles ~ impact + impact^2

where impact = each player's season estimated impact adjusted for expected playoff difference

and titles = a binary variable indicating whether or not the player was a 25+ mpg player on a title team (1 if he was, 0 if he wasn't)

Then I sum up the expected titles for the player's career.


I'll probably also post all the playoff adjusted net ratings and if people are interested I can post the average playoff difference for each player.

Oh wow you did use my suggestion.

So why is Pippen so high now? What's the playoff difference like? That hurts Robinson, but he's still top ten.


Yeah, the playoff adjustment helped Pippen a lot...guys like Hakeem, Kobe, Isiah etc too. Here are the average playoff differences of everyone in the top 100 from the 2011 project:

https://docs.google.com/spreadsheets/d/1DsVfN9F888r36jwXbr5apX7NchRXURMn7SwxSz-9AbM/edit?usp=sharing

I apply that adjustment to the player's impact for each season and use that number in the regression. Really surprised by how much Isiah elevated his game on average...also surprised how much worse Shaq did (I initially expected him to be one of the better playoff performers relative to his regular season production).

It might not be a bad idea to mean regress the adjustment a bit, but no matter how I split it you're either gonna have DRob and Malone being rated higher than you'd expect or guys like Bird, Garnett, and Russell being rated lower.

RealGM Top 100 List #9 -- Bird v. Hakeem

Doctor MJ wrote:So what we're seeing here are two different philosophies:

1. Rank based on what they actually did.
2. Rank based on an idea of they "would" have done.

The second philosophy itself can be broken up into many variants. I've always been pretty tolerant of it as long as it didn't ignore something a player did against himself based on mental immaturity/weakness/etc.

I personally tend to stick to a model that starts focused on (1), and only factors (2) in as a kind of sanity check. This doesn't make for the most consistent possible model, but it allows me to have something pretty consistent that if it has any inconsistency is based on something I feel strongly about.

Interestingly enough, you're mentioning Garnett here as if that has to be based on what he "would" have done, and that isn't how I see it at all. The most objective stats we have for player's actual impact say Garnett had extreme impact for a very, very long time. That alone puts him in contention not only at this point, but earlier.

The fact that Garnett's ALSO more portable than perhaps any other player we've ever seen though, does make his case even stronger.

When we speak of the what "would" have happened, there are players who would be helped if I went more in that direction.

Nash's longevity as a superstar jumps if teams simply understand him earlier.
Magic's longevity as a superstar jumps if he's simply allowed to play.
Bird's longevity as a superstar may very well have jumped if not for an injury he sustained doing manual labor in French Lick, which had nothing to do with basketball.
Wilt's longevity as a superstar jumps if he simply prioritizes helping his teams play basketball better.

The last one is the only one that I really have trouble accepting. Anything else is fair game to me, as long as people can stay consistent and really argue effectively for their thinking. The reason I refrain from going too far in this direction is because I'm skeptical I can do that. And I say this as a kind of connoisseur of ranking things, I've done it compulsively since I was a kid and literally been algorithmist for a ranking website: Sometimes I pick the more conservative approach because I know I can get something meaningful out of it, even if it's not something I call perfect.

Not saying anyone else has to, but it's basically a given that if part way through a ranking project you decide you don't know how to continue in line with what you've been doing, you're far more likely to quit and never refer back to the results again.
where do you draw the line? Do you let wilt play in the nba early? Do walton and stokes stay injury free? Do guys not have to sit out option years for aba?

Well in that chart that floated around eariler, Isiah has the greatest PER increase.

So does this have strength of schedule? That would help Shaq. How do you deal with out of prime seasons? Are you taking a career average playoff adjustment and applying it to every season?
