Using statistics from B-R.com over prior 5 seasons and some defensive adjusted +/- (DAPM) results recently posted online (here), I came up with the following formula for predicting a center's defensive impact: DEF +/- ~= DSPM = -12.34 + 0.12*Ht + 0.95*STL% + 0.16*BLK% + 0.08*DRB% The idea of regressing boxscore stats onto +/- numbers is nothing new. It is referred to as statistical +/-. As you can see, I'm using player height (in inches), and steal, block, and defensive rebounding rates. The pool of players I used to come up with the above formula included every center or forward-center who played at least 2500 minute between 05/06 through last season. I excluded one player from the sample -- Chuck Hayes. The reason being that he has unique combination of very small height and very strong defensive APM, and I didn't want that to potentially distort the prediction. Here is the ranking of centers over the prior 5 seasons based on the above formula: Code: [U][B]Rk Player Ht STL% BLK% DRB% DAPM DSPM diff[/B][/U] 1 Marcus Camby 83 1.8 6.3 32.1 +2.1 +2.6 +0.5 2 Ben Wallace 81 2.3 4.3 22.4 +2.4 +1.7 -0.7 3 Dwight Howard 83 1.3 4.6 30.1 +1.5 +1.7 +0.2 4 Dikembe Mutombo 86 0.9 5 26.3 +1.4 +1.4 +0.0 5 Yao Ming 90 0.7 4.2 24.3 +2.3 +1.4 -0.9 6 DeSagana Diop 85 1.4 5.8 19.5 +0.8 +1.4 +0.6 7 JaVale McGee 85 1.2 6.8 19.6 -1.5 +1.3 +2.8 8 Chris Andersen 82 1.2 7.5 21.9 +1.2 +1.3 +0.1 9 Joel Przybilla 85 0.7 5 27.8 +2.2 +1.2 -1.0 10 Andris Biedrins 83 1.4 3.6 25.1 +1.4 +1.2 -0.2 11 Tim Duncan 83 1.1 4.2 27.4 +3.0 +1.2 -1.8 12 Joakim Noah 83 1.5 3.8 22.8 +0.9 +1.2 +0.3 13 Nene Hilario 83 2 2.6 19.1 +1.5 +1.2 -0.3 14 Samuel Dalembert 83 0.9 5.7 26.1 +0.5 +1.1 +0.6 15 Darko Milicic 85 1.2 5.3 19.2 +0.8 +1.1 +0.3 16 Andrew Bogut 85 1.1 3.6 23.7 +2.9 +1.1 -1.8 17 Marc Gasol 85 1.4 3.4 19.9 +0.9 +1.0 +0.1 18 Chris Kaman 85 0.9 3.8 24.8 +1.0 +1.0 -0.0 19 Chuck Hayes 78 2.4 1.6 21.5 +2.7 +1.0 -1.7 20 Anderson Varejao 82 1.8 2.1 21.7 +2.5 +1.0 -1.5 21 Francisco Elson 85 1.6 2.5 18.8 +0.9 +1.0 +0.1 22 Dan Gadzuric 83 1.6 3.6 19.6 +0.2 +1.0 +0.8 23 Emeka Okafor 82 1.1 4.4 25.5 +1.1 +1.0 -0.1 24 Marcin Gortat 83 1 4.4 25.2 -0.2 +1.0 +1.2 25 Amir Johnson 81 1.5 5.3 19.4 +2.4 +0.9 -1.5 26 Shelden Williams 81 1.7 2.3 22.7 +0.3 +0.9 +0.6 27 Zydrunas Ilgauskas 87 0.9 3.9 20.2 +1.7 +0.9 -0.8 28 Johan Petro 85 1.3 2.6 20.8 -0.3 +0.9 +1.2 29 Al Jefferson 82 1.2 3.3 25 -1.5 +0.9 +2.4 30 Tyson Chandler 85 0.8 3.4 24.6 +1.8 +0.8 -1.0 31 DeAndre Jordan 83 0.9 4.9 23.3 -1.1 +0.8 +1.9 32 Jeff Foster 83 1.5 1.5 22.5 +1.1 +0.8 -0.3 33 Shaquille O'Neal 85 0.8 3.9 22.7 +0.1 +0.7 +0.6 34 Kurt Thomas 81 1.3 2.7 24.8 +2.1 +0.7 -1.4 35 Al Horford 82 1.2 2.6 24.2 +0.8 +0.7 -0.1 36 Antonio McDyess 81 1.5 2 23.2 +0.8 +0.7 -0.1 37 Dirk Nowitzki 85 1.1 1.8 22.4 +1.0 +0.7 -0.3 38 Zaza Pachulia 83 1.7 1.4 18.8 +0.7 +0.7 -0.0 39 Adonal Foyle 82 1.2 5.4 18.4 +1.0 +0.7 -0.3 40 Alonzo Mourning 82 0.5 9.4 18.2 +1.6 +0.6 -1.0 41 Andrew Bynum 85 0.6 4.7 21.6 +0.6 +0.6 -0.0 42 Nazr Mohammed 82 1.2 3.3 21.4 -1.1 +0.6 +1.7 43 Jermaine O'Neal 83 0.8 5 21.3 +1.8 +0.6 -1.2 44 Lorenzen Wright 83 1.6 2.2 17.2 +1.3 +0.6 -0.7 45 Brook Lopez 85 1 4 17.5 -1.3 +0.5 +1.8 46 Brendan Haywood 85 0.8 4.6 18.7 +2.0 +0.5 -1.5 47 Yi Jianlian 85 1.1 2.4 19.4 -0.7 +0.5 +1.2 48 Jamaal Magloire 83 0.7 2.8 26.2 +0.1 +0.5 +0.4 49 Pau Gasol 85 0.8 3.4 20.8 +0.4 +0.5 +0.1 50 Spencer Hawes 85 0.9 3.1 20.1 -1.4 +0.5 +1.9 51 Roy Hibbert 86 0.7 4.9 17 +1.8 +0.5 -1.3 52 Josh Boone 82 1.2 3.1 20.4 -0.7 +0.5 +1.2 53 Hilton Armstrong 83 1.4 3.3 16.1 +0.5 +0.5 -0.0 54 Amare Stoudemire 82 1.2 2.8 20.5 -0.4 +0.4 +0.8 55 Ronny Turiaf 82 1 5.7 17.1 +0.1 +0.4 +0.3 56 Kendrick Perkins 82 0.7 5.1 21.8 +0.6 +0.4 -0.2 57 Brad Miller 83 1.2 1.6 20.8 +0.9 +0.4 -0.5 58 Kwame Brown 83 1.2 2.1 19.7 +0.7 +0.4 -0.3 59 Erick Dampier 83 0.7 4 21.9 +0.8 +0.4 -0.4 60 Chris Wilcox 82 1.3 1.4 20.8 +0.3 +0.3 61 Rasho Nesterovic 85 1 3.4 15.7 +1.2 +0.3 -0.9 62 Chris Bosh 82 1 2.2 22.5 +1.1 +0.3 -0.8 63 Channing Frye 83 1.2 2 18.7 +1.0 +0.3 -0.7 64 Theo Ratliff 82 0.9 5.8 16.3 +0.5 +0.3 -0.2 65 Etan Thomas 81 0.8 5 20.1 +0.1 +0.2 +0.1 66 Raef LaFrentz 83 1 2.9 18.3 -0.7 +0.2 +0.9 67 LaMarcus Aldridge 83 1.2 2.3 16.5 +1.7 +0.1 -1.6 68 Mehmet Okur 83 0.9 1.8 21 -1.4 +0.1 +1.5 69 Tony Battie 83 1.1 2 17.9 +0.4 +0.1 -0.3 70 Mark Blount 85 1 2.1 15.6 -0.5 +0.1 +0.6 71 P.J.

One thing that immediately jumps out is that using DSPM stabilizes the defensive rating considerably, and perhaps too much so. Marcus Camby and Ben Wallace continue to be at the top of the list because of the profile of their individual defensive numbers. Its questionable if that's really a good representation of their defensive impact at this point in their careers, though. Edit: And here is the ranking when I combine DSPM and DAPM (equal weighting).

Why would height be in a stat? Why not include leaping ability, arm span and BBall IQ then? and what is DSPM...what is the "S"
Height is what I had. If I had measures for the other things that seemed relevant like vertical, wing-span, etc., then I'd have included it as well. It turns out that there isn't a particular strong correlation between height and defensive impact (even when excluding Chuck from the sample). Probably because the shorter centers make up for it by being very good in other areas (e.g. Ben Wallace, Kurt Thomas). DSPM: Defensive Statistical +/-.
Its a linear regression, with the output variable being defensive adjusted +/-. You can do it in Excel.
Hey, plot Griffin and Love in your table for this year. btw: even if you had all the physical stats, plus a bball-IQ number, isn't the whole point about stats to be able to not include that stuff. for instance, stats should prove the value of bball-iq or physical skills...that they shouldn't have to be included in formulas. I mean, how do you place a llamda on bball-iq. Coach K playing for Bobby Knight at Army was one of the smartest PGs to ever play the game in the NCAA, but so what?
the problem with stats is there's a p[sychological impact that even prevents attempts surrounding some players, dwight is the most noticable, i remember watching bits of a knicks magic game, felton would be taking the ball down on a fast break see the only person in front of him is dwight, and would simply stop and refuse to attack the basket. That sort of stuff doesn't show up on the stat sheet.
I guess it depends on what you're trying to do. If I want to measure precisely what happened, then I would only consider stats that reflect things that happened on the floor (points scored, rebounds, etc.). On the other hand, if I'm trying to predict or model a player's impact when he's in the game, then I think anything should be fair game including physical measurements. I don't know how I'd go about quantifying basketball IQ. I do think that it is something some teams try to do, though.
That sort of stuff does show up in +/- numbers, which isn't necessarily on the "stat sheet" per se but it is something you can try to analyze and predict.
Have you considered taking a player's defensive foul rate into account? It seems like it would be important to include, though I'm not sure how you'd go about doing it.
You can the majority of those players measurements(wingspan, vertical, etc.) via draft express.. http://www.draftexpress.com/nba-pre-draft-measurements/
+/- is the most inherently flawed stat in basketball, because it has the most reasons and most possibilities to be skewed for reasons not related to the player. The issue is all it can ever produce is correlation, and can never establish any form of causality. And for that reason, It's probably the most valueless in assessing anyone.
Well, of course. Here is a different ranking where I just took the average of DAPM and DSPM (equal weighting). So this combines what happens when the player is on the floor with their individual statistics. Maybe this result is more to your liking: Code: [U][B]Rk Player Ht STL% BLK% DRB% DAPM DSPM diff DASPM[/B][/U] 1 Andrew Bogut 85 1 6.1 26.8 +2.1 +1.6 -0.5 +1.9 2 Tim Duncan 83 1.3 4.9 26.4 +1.9 +1.4 -0.5 +1.7 3 Dwight Howard 83 1.8 4.8 30.2 +0.8 +2.2 +1.4 +1.5 4 Tyson Chandler 85 1 3.4 26.7 +1.7 +1.2 -0.5 +1.5 5 Marcus Camby 83 1.6 5.3 35.4 -0.2 +2.5 +2.7 +1.2 6 Omer Asik 85 1.2 4.8 20.6 +1.2 +1.1 -0.1 +1.2 7 Marc Gasol 85 1.5 4.1 18.8 +0.9 +1.1 +0.2 +1.0 8 Kurt Thomas 81 1.6 3.3 20.1 +1.2 +0.7 -0.5 +1.0 9 Jason Smith 85 1.1 2.6 17 +1.4 +0.4 -1.0 +0.9 10 DeAndre Jordan 83 1.2 5.3 21.5 +0.6 +1.0 +0.4 +0.8 11 Pau Gasol 85 0.9 3.8 20.4 +1.0 +0.6 -0.4 +0.8 12 Joakim Noah 83 1.7 3.4 23.2 +0.2 +1.3 +1.1 +0.8 13 Zydrunas Ilgauskas 87 1.1 4.4 19.4 +0.4 +1.1 +0.7 +0.8 14 Roy Hibbert 86 0.5 4.7 22.4 +0.8 +0.7 -0.1 +0.8 15 Greg Monroe 83 2.3 1.5 19.2 +0.1 +1.3 +1.2 +0.7 16 Andrew Bynum 85 0.2 5.5 21.4 +1.1 +0.3 -0.8 +0.7 17 Shaquille O'Neal 85 1.2 4.3 19.9 +0.4 +1.0 +0.6 +0.7 18 Andris Biedrins 83 1.6 2.6 25 +0.1 +1.2 +1.1 +0.7 19 Samuel Dalembert 83 0.6 6 24.3 +0.4 +0.8 +0.4 +0.6 20 JaVale McGee 85 1.1 7.2 21.4 -0.2 +1.4 +1.6 +0.6 21 Anderson Varejao 82 1.4 3 24.8 +0.2 +1.0 +0.8 +0.6 22 Emeka Okafor 82 0.6 4.5 25.9 +0.7 +0.5 -0.2 +0.6 23 Nene Hilario 83 1.7 1.9 21 +0.1 +0.9 +0.8 +0.5 24 Al Horford 82 1.2 2.4 24.3 +0.3 +0.7 +0.4 +0.5 25 Antonio McDyess 81 1.5 1.9 22.9 +0.3 +0.6 +0.3 +0.5 26 Anthony Tolliver 80 1.1 2.2 17.3 +1.1 -0.3 -1.4 +0.4 27 Chuck Hayes 78 1.8 2 19.8 +0.4 +0.3 -0.1 +0.4 28 Amir Johnson 81 1.4 3.1 18.4 +0.2 +0.4 +0.2 +0.3 29 Derrick Favors 82 0.8 2.8 18.3 +0.7 -0.1 -0.8 +0.3 30 Ben Wallace 81 2.5 3.6 23 -1.4 +1.9 +3.3 +0.3 31 DeMarcus Cousins 83 1.6 2.2 22.9 -0.5 +1.0 +1.5 +0.3 32 Joel Anthony 81 0.4 5.9 12.4 +0.9 -0.6 -1.5 +0.2 33 Spencer Hawes 85 0.7 2.9 23.3 -0.3 +0.5 +0.8 +0.1 34 Zaza Pachulia 83 1.3 1.5 19.3 -0.1 +0.3 +0.4 +0.1 35 Marcin Gortat 83 0.9 3.6 25.5 -0.7 +0.8 +1.5 +0.1 36 Brendan Haywood 85 0.5 4.1 19.6 -0.1 +0.2 +0.3 +0.1 37 Brook Lopez 85 1 3.4 11.9 +0.1 0.0 -0.1 +0.1 38 Brad Miller 83 1.6 1.6 18.3 -0.5 +0.6 +1.1 +0.1 39 Semih Erden 85 1.3 3.1 17.6 -0.7 +0.7 +1.4 0.0 40 Kwame Brown 83 0.6 2 22.7 0.0 0.0 0.0 0.0 41 Nazr Mohammed 82 1 4.9 22.8 -0.9 +0.7 +1.6 -0.1 42 Channing Frye 83 1.1 2.4 19.2 -0.6 +0.3 +0.9 -0.2 43 Ed Davis 82 1 4 21.5 -0.8 +0.5 +1.3 -0.2 44 Amare Stoudemire 82 1.3 4.3 18.6 -1.1 +0.6 +1.7 -0.3 45 Al Jefferson 82 0.8 4.6 22.2 -1.2 +0.5 +1.7 -0.4 46 Nenad Krstic 85 0.9 1.3 14.1 -0.5 -0.2 +0.3 -0.4 47 Robin Lopez 85 0.6 2.9 13.7 -0.7 -0.3 +0.4 -0.5 48 Jordan Hill 82 0.4 3.1 16.7 -1.7 -0.6 +1.1 -1.2
Great work! I like your analysis, it makes sense. Dalembert is supposedly on the block but with this analysis you can see that he is a slightly above average center in Terms of D.
Defense is so hard to measure. This is a good attempt, durvasa. Have you considered adding something like FG% allowed or eFG% allowed? I look at the stat on 82games often but am just not sure how valuable it is. Based on the list of centers, if we have no shot at McGee, then our best hope is probably Biedrins, Dalembert, or Mohammed. I think getting a veteran C now to stop the bleeding this year is fine as long as we can draft a young C this year. It's hard to imagine our team being able to get a Nene, McGee, or Marc Gasol.
I combined DSPM and DAPM and added the results to the end of the first post. It passes the Jordan Hill test -- he's dead last.
Exactly, correlation doesn't equal causation. This is what people with a dogmatic view of statistics do not understand, the same people that believe leadership can be quantified... based, for example, on how early somebody shows up to practice. Omer Askik? Lol, you have got to be kidding me.
