The 2011-2012 NBA Wins Produced Cheat Sheet

I was born not knowing and have had only a little time to change that here and there.

The New Kings

At the end of last season, I was arrogant. I was at the top of my game. I felt I had an answer or a model for every possible scenario the NBA could throw at me.

Then everything changed.

First, we didn’t know if we would have a season.Then we didn’t know where Chris Paul and Dwight Howard would end up. We still don’t know who’s going to be playing where exactly. Never mind the fact that the schedule for the season is so strange that Vegas refused to post over/unders for wins for the season.

But I wasn’t worried, All I had to do was adapt all my existing models slightly to account for the variation right?

Yeah, about that…

One of the projects that we had been working on is on improving the Wins Produced model . The Lockout gave us a great opportunity to do so and we did. This is a very good thing.

Except that it means that the world changed. Up is not quite down but it’s not exactly up anymore. The value and contribution of each player has changed and it’s going to take a while to adjust to the new reality.

It’s easy for anyone to be confused.

Luckily, I’m here to help you with that and I’ve been in the lab working on the problem. To start, I decided to come up with a nice little cheat sheet for the New Wins Produced model. It features every veteran currently on an active roster and it’s sorted by team and by the players Wins Produced for the 2010-2011 season. It has basic information for each player, totals for the last five years, each players average year and the numbers for the 2010-11 season.

Hopefully, that will help everyone involved.

Checking in on a Prediction

Economists aren’t known for getting predictions right.  Nevertheless, we keep trying. 

My latest prediction – which was revealed in an article by Ron Dicker at Huffington Post – was that television ratings for NBA games this Christmas would exceed the ratings seen for games played on Christmas last year.  This prediction — made a few weeks ago — was motivated by the research I published with Martin Schmidt on the impact labor disputes have on attendance.  As we noted in The Wages of Wins, fans may say during a labor dispute that they will hold a grudge, but the data makes it clear that this is an empty threat.  Although this research was about attendance, I predicted we would see a similar story with respect to TV ratings.  And as I revealed today in my latest at Freakonomics…. well, go read the post. 

I will add this bit of information.  In the 33 days since the NBA lockout ended, we have had more than 90,000 page views at the Wages of Wins Journal (according to WordPress).  From November 26 to December 28 of 2010 (or last year at this time), this blog only had about 53,000 page views.  This is somewhat surprising, since NBA games were actually being played for this entire time period in 2010.  But one suspects that fans became very interested in the NBA once the lockout ended. 

Then again… last year the primary writer in this forum was me.  And this year, other people are doing almost all the writing. So maybe this all simply reflects a change in the talent level in this forum :)

Yes, Al Harrington is that bad.

I use the “basic” stats for this post to show how terrible Al Harrington is. That said, the Wins Produced numbers have been saying that for years. Why don’t you check out our Wins Produced numbers for yourself!

Some players are terrible. The dangerous players are the terrible players that for one reason or another people think are good. Maybe they have potential or are a game changer or are a shot creator. The thing is none of those excuses can really mask the fact that the players are bad. Still, fandom can have the side effect of rationalizing bad play. Trust me, I’ve been there (I used to think Melo and A.I. were capable of winning a title) So we’ve decided to help. I’ll be looking in depth at a few players that despite the contracts, the crazy claims and other factors are in fact bad.

Al Harrington

Signs people think he’s still good:

  • He’s signed to a contract with 4 years and over $25 million left on it.
  • He’s also still getting over 20 minutes per game.

Why people probably think he’s good:

  • Al Harrington has averaged over 10 points per game his entire career.
  • Al Harrington shoots well from three point land. At his peak Al Harrington was hitting over 45% from distance. Last season he still hit a respectable 35.7% from three.

Al’s not a great shooter

First off Harrington’s impressive shooting? It’s not that impressive. Using the great NBA Geek Player Comparison Engine, here’s how an average power forward’s shooting line looks compared to Harrington the last few seasons

Al Harrington’s shooting compared with an average 2010-2011 PF
Player Two Pointer % Three Pointer % Free Throw % True Shooting %
 Average 2010-2011 PF 49.4% 35.9% 74.1% 54.4%
 Al Harrington 2010-2011 48.0% 35.2% 76.0% 52.7%
 Al Harrington 2009-2010 49.1% 34.3% 75.0% 54.6%
 Al Harrington 2008-2009 48.6% 36.4% 78.6% 55.5%

The truth is that in recent years Harrington shooting has been average to below average. Two seasons ago he was slightly better than the average power forward when it came to getting the ball in the net. I know the phrase that makes me want to throw $30 million at a player is “Slightly above average”

We can view the final effect of Al’s shooting using Points per Shot (PPS). This looks at how many points a player makes per shot they take. A free throw is counted a 44% of a shot because that’s the percentage of the time it ends a possession. Fun right?

Another look at Al Harrington’s Shooting (per 48 minutes)
Player FGA FTA PpS Pts
 Average 2010-2011 PF  17.0 5.4 1.08 21.0
 Al Harrington 2010-2011  19.5 3.4 1.05 22.1
 Al Harrington 2009-2010  22.5 6.9 1.09 27.9
 Al Harrington 2008-2009  22.0 5.7 1.11 28.4

Last season Al Harrington was actually below average when it came to shooting. In exchange for two extra shots per game compared to his fellow power forwards he was able to generate 1 extra point. If that sounds like a bad deal… well it is. Even in 2008-2009 (which was his best season ever as a scorer) he produced 28.4 points per 48 minutes. Had an average power forward taken the same number of shots as Harrington they’d have pulled down 26.4 points per 48 minutes. So at his peak (which has since passed) Al Harrington’s scoring was less than 8% better than his peers. Of course he masked such a small difference with volume. Al Harrington has shot between 15% to 25% more shots per minute than his peers.

Al is terrible at rebounding

Now we might argue alright so Harrington isn’t really above average at scoring but hey average scoring is worth something right? There’s one other caveat and that is rebounding. You see a power forward really has two jobs. They’re close to the hoop so they should be able to score more. Additionally they should get the team the ball in the event of a miss. Per 48 minutes an average power forward should grab around 11.6 rebounds. How has Big Al stacked up?

A look at Harrington’s Rebounding per 48 Minutes
Season ORB DRB Total
2010-2011 2.1 7.3 9.4
2009-2010 1.9 6.9 8.7
2008-2009 1.9 6.7 8.6

In 2011 Al got close to his career high in boards per minute with 9.4. Of course, that still a good two rebounds fewer than an average power forward would be expected to grab. In fact going on the percentages that a good 23% below what’s expected. So at one of his assigned tasks Harrington is not just bad, he’s terrible.

Al’s not good at anything else

So Al is average to below average at shooting and woefully below average at rebounding. The last nail in the coffin is Al is not really good at much else either.

A look at the rest of Al’s stats (per 48 minutes)
Player Assists Turnovers Blocks Steals Fouls
 Average PF 2010-2011 2.7 2.5 1.2 1.2 4.6
 Al Harrington 2010-2011 2.9 3.1 0.3 1.1 5.9
 Al Harrington 2009-2010 2.4 2.9 0.5 1.3 4.5
 Al Harrington 2008-2009 1.9 3.1 0.4 1.6 4.3

If big men are expected to block and rebound then Harrington clearly never got the memo. Last season he was marginally above average when it came to passing, which is of course what you expect of your power forward. Also, it is not actually common as typically Harrington is below average in regards to passing. A few seasons ago Harrington’s stealing was decent. That might almost be enough for me to give him some credit. Of course when we look at his turnovers we find any benefit from his stealing is more than offset by his tendency to give up the ball.

Summing up

Al Harrington is a classic example of the overrated player at the Wages of Wins. By putting up lots of shots he has been able to up his point totals and as we’ve seen time and time again, this is what gets players paid. However, when we break down Harrington we find he was marginally better at scoring and worse at everything else expected of a power forward. So yes, Al Harrington is that bad.

On a final note. A common theme you might see with Al Harrington is that he can “take over a game” or “have a big night when it matters”. I want to stress that virtually any player in the NBA if given enough opportunities to shoot the ball a lot can have a big night. Heck Adam Morrison and Michael Olowokandi were both able to get 30 point games in their careers. So rather than put faith that a bad player may come through in a random game, it may just be a better idea to put the same faith in good players instead.

P.S. When I first threw this idea around I thought I might do it for all players in the NBA that came to mind. Patrick was quick to point out that would take me forever. Instead I decided to do an in depth look at one such player. If you have other overrated players you’d like us to examine then please shout them out. Michael Beasley is already on deck!

Awesome NBA links

With the season in full swing there’s actually been some pretty cool basketball related blog posts.

Mosi Platt(@MIA_Heat_Index) over at the Miami Heat Index has been keeping busy.

wiLQ(@Exploring_NBA) over at Weakside Awareness has had some real gems including

Patrick Minton(@nbageek) over at the NBA Geek has been on an absolute tear.

Jamie Vann Struth(@JamieVannStruth) over at Raining Buckets has forecasted the 2011-2012 season. Of course Jamie admits there are many things out of his control with his predictions and as such we shouldn’t think of them as written in stone. However there are some cool takeaways based on how the lines currently stand:
  • People are sleeping on Denver and the Clippers. Jamie has them finishing in the top 3 out west.
  • The Hornets will miss Chris Paul and their new young players will not even come close to making up for it.
  • Dallas is nowhere near the contender people are making them out to be. Jamie has them missing the playoffs!

Ben Gulker(@brgulker) at Pistons by the Numbers is back! Sadly the news isn’t happy – it’s insanity to think Pistons will win even 30 games.

In case you missed this: Ian Levy(@HickoryHigh) over at Hickory High compiled a holiday wish list of pretty much every NBA blogger on the net!

If your team is still scrambling to make a move Arturo Galletti(@ArturoGalletti) has a complete breakdown of the NBA Free Agents

Enjoy! And as much time as our talented staff puts into combing the web for awesome basketball content, we have no hope of reading it all. If you see a cool link or post you think we should mention feel free to shout it out in the comments.

Toronto will be terrible.

The following post uses the Wins Produced metric. During the long offseason Dave Berri took a little time to tweak it a little. You can find all of the numbers for last decade or so here, as well as a handy tutorial!

It’s opening day as I write this, so now’s a good time to get my Raptors prediction out there. Numbers first, with an explanation to follow:

Player Pos. Pred. WP48 Pred. Mins Pred. Wins Lockout Adj.
Ed Davis PF 0.190 2321 9.19 7.39
Jose Calderon PG 0.168 2033 7.13 5.74
Amir Johnson PF 0.196 1615 6.59 5.30
Aaron Gray C 0.123 700 1.80 1.45
DeMar DeRozan SG 0.031 2800 1.80 1.45
Jamaal Magloire C 0.156 423 1.37 1.11
James Johnson SF 0.032 1000 0.66 0.53
Gary Forbes SF 0.027 1000 0.56 0.45
Anthony Carter PG 0.083 300 0.52 0.42
Leandro Barbosa SG 0.010 1136 0.24 0.19
Jerryd Bayless PG 0.005 1603 0.16 0.13
Rasual Butler SF -0.004 1100 -0.08 -0.07
Linas Kleiza SF -0.034 836 -0.59 -0.47
Solomon Alabi C -0.189 300 -1.18 -0.95
Andrea Bargnani C -0.072 2513 -3.77 -3.04
Total 0.060 19680 24.40 19.64

Last year’s Raptors finished with 22 wins, and if this year’s team played a full 82 game season, I’d put them at 24-25 wins. As this season will only be 66 games, I have to adjust that total accordingly, and I get about 19-20 wins.

Individually, the team should be led by three players — Ed Davis, Jose Calderon, and Amir Johnson — who should account for the vast majority of the team’s wins. I expect all other players on the team’s roster to account for only about one win.

This season’s new acquisitions — Aaron Gray, Jamaal Magloire, Gary Forbes, Anthony Carter, and Rasual Butler — will only add about three wins. Gray and Forbes are the most promising, but probably won’t see very much playing time; Magloire and Carter are formerly decent veterans who are old, have been declining for years, and could drop off a cliff at any moment; and Butler should end up being the least productive of the bunch (older and never productive). Thankfully, each of these newly acquired players is cheap and on a one-year deal, so the long term ramifications of these signings will be minimal.

As far as departed players go, Sonny Weems will not be missed. After a promising 2009-10 campaign, Weems regressed significantly last season. It’s a good thing he’s now stuck overseas. The other Raptor stuck overseas is Joey Dorsey. Dorsey was quite productive in limited minutes last season — as he has been for his entire career — so it’s a shame he won’t be back. The other two players the Raptors should miss are Julian Wright and Reggie Evans. Wright was also productive in limited minutes last season, but with the arrival of James Johnson, there was very little chance of him returning. Hopefully he gets another chance with an NBA team in the future. Evans was excellent last season, but he was limited to about 800 minutes due to injuries. While he is a productive player, he is older, injury prone, and plays the same position as two of the team’s three best players. I’m glad he ended up on a team that’s likely to be playoff-bound and will have a use for him.

(Brief aside: it’s also a good thing that Chris Kaman is no longer on the Clippers, because that might have been awkward)

Yes, the Raptors were relatively stacked at the power forward position last season. As I noted above, two of the team’s “modest three” play this position. If I arrange the numbers by position, we can see the impact this has even more clearly:

Pos. Pred. WP48 Pred. Mins Pred. Wins Lockout Adj.
C -0.022 3936 -1.78 -1.43
PF 0.192 3936 15.78 12.70
SF 0.007 3936 0.56 0.45
SG 0.025 3936 2.04 1.64
PG 0.095 3936 7.81 6.29
Total 0.060 19680 24.40 19.64

Power forward will continue to be the team’s strength. The point guard position will be roughly average — a relative strong point for Toronto. Shooting guard, small forward, and centre will all be around a WP48 of zero; there will be a small number of wins produced at SG, but most of these wins will be offset by the losses created by the team’s centres (specifically the team’s least productive player).

I will conclude the post with my standard disclaimer for making pre-season predictions: I do not pretend to have exceptional forecasting abilities. My prediction method involves a three year weighted average of both WP48 and minutes played, with adjustments made to minutes to make the minutes add up properly. I can’t predict injuries, trades, or playing time, nor can I predict players who have uncharacteristic seasons. But I’m sure that you knew that already.
