Adjusted Player "dWin%"

This is, as far as I know, the first publicly available Adjusted "Win%" metric for NBA players.

For a quick refresher, here's the theory:

1) Adjusted plus-minus data uses a regression equation to determine which player impacts team point margin the most, etc.
2) We can determine the probability of any team winning a game based on location (home or away), time left, and point margin. (I'm using Kupfer's old estimate).
3) According to this (and Ken Pomeroy, NCAA guru), there are certain points in the game with much more leverage than others.
4) Increasing your lead by 1 point is much more valuable to your team's win with 1 second left while the game is tied than at the beginning of the game when it is tied (i.e. clutch points>average points>"garbage time" points).

Using this, I have given each game substitution from the 2011 season play-by-play a "delta Win% per 100," showing the degree that each team's win% has changed. Using this instead of Efficiency Margin, I simply followed the steps in Eli Witus' golden blog post of old for the 2011 regular season.

I penalize high standard errors and reward low standard errors (by converting value+SE into a NormDist function then back into a value), thus making the system look slightly more like rAPM than APM.

You'll notice that some players have extremely high values that don't necessarily make sense; remember that in-game-Win-probability has a limit (it cannot exceed 100%). These rankings do not share that, (i.e. putting Dirk on an average team for a whole game would not win>120% of their games) since per-100 Win% can have extreme highs and lows. If you'd rather, simply move the decimal place over two spots to the left in your mind and consider that "delta Win% per possession."

Without further ado, here are the rankings:

The Supporting Cast picks up The German's Slack - Game 6

LeBron had a bad day - but so did Dirk.

Bosh, Chalmers, and Wade are the only Miami players who appear to have a positive impact.

The Biggest Game of Lebron James' life...was awful.

Dallas won by 9 points, which is 10.4 points per 100 possessions.

I split credit of the team's point margin in half, adjusted for pace, quality of opponent, and home-court-advantage.

Dallas played like a +4.98 team
Miami played like a -4.98 team

TOV%=percent of a player's possessions that ended in a turnover (basketball-reference.com's boxscore).
ORTG=offensive rating. very complex measure for efficiency
DRTG=defensive rating, similar to the above.
+/- = Plus-Minus rating, as tabulated by ESPN's box score. It shows the change in point margin while a player is on the court.

Raw est APM(100)= an estimate (using the above) of how much a player impacted his team's point margin per 100 possessions.

Adj est +/- (G) = an estimate of how much a player impacted his team's point margin per 100 possessions

MIA	LeBron James	45.63	16.8	98	131	-11	-2.23	-1.56

(Here is a quick spreadsheet that explains how I currently estimate APM.)

James played nearly every minute of this game, and didn't really succeed. Per-possession, Bibby had a much worse game, however.

EDIT: By the way - these numbers are based on a prediction of these ratings.

Another Look @ Game 3

based on Engalmann's latest adjustement to Regularized Adjusted Plus-Minus

(Plus-minus number also gives us estimates for OnCourt +/- per 100 minus OffCourt +/- per 100, and teammate OnCourt minus OffCourt, both of which adjust the Offensive Rating, Defensive Rating, and Turnover% values)

Game 3! (Somewhat late...)

The formula is confused as to how Dallas lost. (Total contrib of around 11 versus Miami's 6).

Miami leads, 2-1.

Game 2! (Very late...)

I finally came up with a formula that helps regress crazy values (i.e. Dirk off the court was worth -100 points per 100 possessions in game 2).


"Adjusted" +/- per 100 is a simple combination of Net +/- (ON - OFF), offensive rating, and defensive rating

GAME 1, NBA FINALS

Wayne Winston & more recently Kevin Pelton like to use +/- in their discussions on player performance. But Statistical plus-minus geeks like myself are dissatisfied with simple Net +/- ratings. It should be noted that I have not implemented any system that regresses towards the mean for small sample sizes. I will incorporate this later.

Here is how the Heat & Mavericks stack up in my combined system.

Adj. Rating = estimate of how much the player contributed to his team's point margin, per 100 possessions*
Contrib = estimate of a player's total contributions to their team's point margin during play

st. ORAPM = advanced stats prediction of offensive Regularized Adjusted Plus-Minus
st. DRAPM = same^, except defensive RAPM
Statistical RTG = st. ORAPM + st. DRAPM

Net Plus-Minus = On-Court Team Efficiency Margin (per 100) minus Off-court Team Efficiency Margin

Recent Tw-happenings

I've been posting all kinds of nonsense to twitter lately. Here are some of the more informative tweets:

1) Lineup stuff:

•  J.E. has released the first public Adjusted Lineup data. 
• The Big 3 (+2 specific players) is the 3rd worst lineup in the NBA (see above), and Miami used this lineup in the playoffs.
• This is confirmed by the fact that said lineup only scores more points than their opponents 40% of the time.

2) Jason Kidd has played the best defense (of Miami & Dallas players) during the playoffs.

3) Nick Collison is not represented well by box-score or advanced box-score statistics.

4) I put together Lebron James' year-by-year Statistical and Actual Regularized +/- numbers since '08.

Most (& Least) Valuable Players in the 2011 Playoffs, Pre-Finals Edition

EDIT: I have also posted the most & least efficient players to Google Docs (as many of the poor performances don't make it into the bottom 25 as such players lost their series).


Here are the top & bottom 25, respectively. (These are not adjusted for opponent quality).

The numbers are based on my statistical plus-minus numbers, which I convert to wins via the "Pythagorean" formula. (Although I give each player the same baseline "team" value here for simplicity).

	Player	Tm	win% added per game	playoff wins added
1	LeBron James	MIA	18.9%	2.84
2	Kevin Durant	OKC	16.5%	2.80
3	Dirk Nowitzki	DAL	14.5%	2.17
4	Dwyane Wade	MIA	12.3%	1.85
5	Jason Kidd	DAL	10.7%	1.60
6	James Harden	OKC	9.2%	1.56
7	Derrick Rose	CHI	9.6%	1.54
8	Chris Bosh	MIA	8.3%	1.25
9	Joakim Noah	CHI	6.8%	1.09
10	Chris Paul	NOH	17.7%	1.06
11	Zach Randolph	MEM	7.7%	1.00
12	Jason Terry	DAL	6.3%	0.95
13	Kevin Garnett	BOS	10.4%	0.94
14	Ray Allen	BOS	10.2%	0.91

NBA PLAYOFF PLAYER RATINGS as of 5/24

Earlier today, I made a prediction formula (regression) that predicts a player's Adjusted Plus-Minus based only on the advanced stats which Basketball-Reference spits out*

The following is their estimated Adjusted Plus-Minus, their total (pace-adjusted) personal point differential, and their total value to their team per 100 possessions (eRAPM * ~Min%).

MATH:

 *I used Basketball Reference's '07-'11 career advanced stats and Engalmann's Regularized three-year offensive and defensive +/-, for all players with >1000 minutes played. I made a regression (with no intercept), gradually weaning out variables with a P-value of >.05, and the following is the result:

(Offense has an R^2 of ~.6, Defense of ~.4)

Win Shares per 48 Minutes versus Easy Player Ratings

Since Win-Shares per 48 minutes and my Easy Player Ratings use the exact same data (although EPR also adds minutes per game) to calculate player "efficiency," I thought I would compare the two.

I took all NBA players from in the 3-point era who played more than 1000 minutes and looked at their WS/48 and EPR values. From there, I just had a look at the top 100 in Win-Shares per 48.

Most notably, David Robinson (3.36 EPR) beats out Michael Jordan (3.27 EPR), barely -- this is somewhat intuitive, as Jordan's old years in Washington significantly decrease his "average," likely from his poor defensive numbers.




Now here are the 10 players in the top 100 who WS/48 comparatively likes the most:

	Player	From	To	USG%	ORtg	Points Prod Per 100	DRtg	MP		WS/48	(rk)		EPR	(rk)	difference
1	Leon Powe	2007	2011	20.4	115	23.46	103	13.9		0.174	33		1.17	88	-55
2	Steve Mix	1980	1983	21.7	113	24.521	103	17.2		0.168	39		1.18	87	-48
3	Marcin Gortat	2008	2011	15.3	116	17.748	102	17.2		0.162	46		1.17	89	-43
4	Steve Nash	1997	2011	21.2	119	25.228	110	31.3		0.168	39		1.22	80	-41
5	Kevin Love	2009	2011	22.1	117	25.857	109	29.8		0.163	45		1.19	86	-41
6	Mark Price	1987	1998	22.8	116	26.448	109	29.9		0.158	52		1.14	93	-41
7	Ryan Anderson	2009	2011	20.7	115	23.805	105	18.9		0.157	53		1.08	94	-41
8	Amir Johnson	2006	2011	14.3	122	17.446	107	17.8		0.154	61		0.80	99	-38
9	Carl Landry	2008	2011	20.5	117	23.985	108	24.9		0.155	60		1.04	95	-35
10	Todd MacCulloch	2000	2003	17.7	113	20.001	100	15.4		0.166	43		1.32	74	-31

Unfortunately, Steve Nash's lower usage and nearly non-existent defensive stats underrate him in EPR. Personally, I think Nash is in the top 5 offensive players of all time, which his usage and Offensive Rating do not capture well. Not sure where the rest of these guys fall - it could be because of low minutes-played, but that term is not worth all that much.


Here is a look at the players in the top 100 who the EPR system likes more than WS/48:

	Player	From	To	USG%	ORtg	Points Prod Per 100	DRtg	MP		WS/48	(rk)		EPR	(rk)	difference
1	Patrick Ewing*	1986	2002	28	106	29.68	99	34.3		0.15	77		1.83	28	49
2	Jack Sikma	1980	1991	20.9	110	22.99	102	33.7		0.149	82		1.58	44	38
3	Scottie Pippen*	1988	2004	22.5	108	24.3	102	34.9		0.146	94		1.49	57	37
4	Eddie Jones	1995	2008	20.1	111	22.311	103	34.4		0.147	89		1.52	53	36
5	Dennis Rodman*	1987	2000	11.4	114	12.996	100	31.7		0.15	77		1.59	42	35
6	Horace Grant	1988	2004	15.2	117	17.784	104	33.2		0.147	89		1.51	54	35
7	Dikembe Mutombo	1992	2009	15	111	16.65	99	30.8		0.153	69		1.72	35	34
8	Jeff Ruland	1982	1993	22.3	109	24.307	102	33.4		0.149	82		1.53	51	31
9	Dominique Wilkins*	1983	1999	30.3	112	33.936	108	35.5		0.148	85		1.45	60	25
10	Peja Stojakovic	1999	2011	21.5	114	24.51	106	33.5		0.147	89		1.41	66	23

EPR likes moderately high usage at average offensive rating, which explains Ewing near the top. In my regression, Ewing's efficiency + usage is above the threshold of having negative (relative) impact. Not quite sure what to make of the rest.



At any rate, here is the entire list of the top 100 players by WS/48
