NBA Possesion Analysis Part 1: Best Offensive Player.

Tuesday, November 20th, 2007

As I look around the basketball blogosphere, read journalist evaluations, and listen to fan opinions – it seems to me that we are really lacking an understanding of what it takes to win basketball games, and as a result we Lose Weight Exercise/”>Lose Weight Exercise focus of which stats we should really pay attention to.  As far as I’m concerned, basketball is a game of possessions and opportunity cost. I don’t care if a team scores 75 points or 125 points, of if it concedes 80 points or 120 points. We all know that different styles of play can be successful, from San Antonio’s grueling half court sets to Phoenix’s lightning paced tempo. But what is important is how efficient teams and players are with the amount of possessions they do have. Essentially, if you have more ‘successful possessions’ on offense than your opponent does, then you win the game. It doesn’t matter if you beat your opponent 4-2 or 133-131 right?

Therefore through offense and defense the key is to make the most of your possessions while denying your opponent of successful possessions. Today I will evaluate the offensive side of the game and rate the players according to their stats in the 06-07 season. To do this I have created a unique formula that will calculate in detail how each player uses up their respective possessions. Practically all statistics that we use today have some sort of contribution to the analysis of possessions – its just that they have never been put into the right formula before.

 

So before I reveal my findings, let me explain a bit more about this business of ‘possessions’.

 

In basketball the goal IS actually to have more points than your opponent, but while points is the end product we are looking for, it is possessions that is the scarce resource that makes it happen. In other words, possessions are what creates points. Since a team has a limited amount per game, then it makes every bit of sense that teams and players should try turn as many possessions into successful possessions. For example a player giving you 4/5 from three point land is far far better than another player shooting 6/13 from the field, because he gets you the same points in 8 less possessions. With the first player, those 8 extra possessions instead of missed shots, can be turned into more points. Therefore we should analyze a player’s possession use efficiency to determine his offensive worth to a team. To calculate the efficiency we simply need to consider potential possessions and successful possessions:

 

One made shot is one potential possession, turned into one successful possession. Similarly, a missed shot is 0 successful possessions out of 1 potential possession. With an assist you are responsible for half of the successful possession with half the potential. Free throws similarly count as 1/1 in terms of possession use when making both, 0.5/1 when making 1 of 2, and 0/1 when missing both. Turnovers count as 0/1 in terms of possession success obviously.

 

After adding some modifications to take into account: free-throws that come as a result of and 1’s, giving scoring players half the credit when they score off of assists, and giving 3 point baskets 1.5/1 in terms of possession success, we can calculate a players’ possession success percentage. This is calculated by dividing all the successful possessions by potential possessions. (It is important to understand that by possession we mean that the player in question did something that led to the change in possession of the ball to the other team – either good or bad).

 

This percentage tells us simply what percentage of the time the player in question will help create two points when he uses the teams’ possession. So if someone has 80% successful possession ratio, it means that 4 out of 5 times the player will help the team secure two points – this could be a made shot, an assist, or freethrows made, the important thing is that the team ends up with 2 points. It obviously would make sense for teams to highly value players with good possession success % because they make the most out of a teams’ limited possessions.

 

So after some complex calculations that I won’t bore you with at this moment, here are the top 50 most efficient offensive players for the 06-07 season (500 minutes had to be played in order to be eligible): 

 

TOP 50: MOST EFFICIENT OFFENSIVE PLAYERS

Now, we should be careful when looking at this table to not make quick conclusions. The ranking does not suggest that Brent Barry is a better scoring shooting guard than Kobe and Wade…absolutely not. However, it does statistically prove that he was more efficient with his possessions than those superstars. You can see on the list that Steve Nash is number 1, and this should be no surprise to most as he always seems to make good things happen on offense. We can also see through this list that role players that are valued highly in coaches minds such as Battier, Lee, Najera, Hermmann, Barry etc all justify their worth as they manage to be more efficient than their superstar counterparts.

 

With that said, this ranking doesn’t do justice to those superstars that have so much more responsibility and have to keep producing despite fatigue and double teams, and are expected to produce on a consistent basis. Therefore, we should also see which players create the most useful possessions per game:

 

TOP 50: USEFUL OFFENSIVE POSSESIONS PER GAME

 

totaluseful.JPG

 

This is essentially a Top 50 of who creates the most on offense for his team. It is no surprise that the list is made up of the top offensive players in the league. The top 23 in fact are all in different teams (if we ignore that Iverson went to Denver in the middle of the season). This list on the other hand discriminates against players who don’t ‘ballhog’ and don’t get as many minutes. Therefore a better representation of a player’s offensive worth would be if we calculate the offensive successful possession surplus. This means, how many successful possessions does the player create after we subtract his unsuccessful possessions. This is a much better representation since superstars are still rewarded for having that burden to consistently contribute, whilst efficient players are still rewarded over ‘ballhogs’ for their more efficient performance. Since every successful possession in our calculations translates into two points, here is the ranking of top 50 players who contribute the most NET points to his team.

 

TOP 50: Net Points Gained aka “The Oytun Offensive Efficiency Rating” (OOER)

 

net-points.JPG

 

We should make it clear when looking at these numbers that the league average % chance of creating a successful possession is 51%. For conveniences sake if we assume that it is 50%, then we can understand that that average point surplus of the league is 0. This means that an average player will use half his possessions to create two points, and the other half will lead to nothing. Our list shows how many NET points these elite players contribute to their teams. Keep in mind that even if a player averages 50 points and 20 assists per game, he won’t be more useful than an average player unless his efficiency is above that of an average player. Having said that the above is a good representation of how many points the team would Lose Weight Exercise/”>Lose Weight Exercise if that player was injured to be replaced by an average player. Of course there are flaws with this assumption, but it is still as good an understanding we will get of how much value a player has to his team on offense.  Therefore if the MVP chase was based solely on offensive contributions the above list should serve to rank them.

 

TOP 20: OOER per 40 minutes

Moving on to some more ‘fun’ stats. I don’t like ‘per 40 minute’ stats because it is highly misleading, but for those who believe in it, here are the top 20 offensive contributors if everyone in the league played 40 minutes.

 netper40.JPG

 

TOP 20: Ball Hogs

Which players are most ‘active’ on the offensive end of the floor? Below are the top 20 biggest Ballhogs. (most possessions used per minute played)

So those Kobe fans who keep hearing how much of a ballhog Kobe is, they can now respond by saying that there are three other players who are bigger ballhogs than him, and also less efficient at the same time.

 

 

TOP 10: Worst Offensive Players

It is also useful to know who you do not want on the floor when you crucially need a basket. Here are the top 10 players who harm their team the most on a per 40 minute basis:

 

 

worst.JPG

 

So keeping Bonzi on the floor for 40 minutes will lead to 9 less points for your team per game than the average NBA player. Minnesota fans might be concerned to see two of their key players on this list. (Sorry ‘Toine!)

 

 

End of Part 1 

 

Well that wraps up the offensive side of things. We’ve seen that in the 06-07 season, while Kobe created the most ‘good’ for his team, he doesn’t do it nearly as efficiently as Steve Nash. In fact, the 2 time MVP is way ahead of the competition when it comes to offensive performance. Some might point to the fact that the Suns play a much higher tempo game, but Nash is not even in the top 15 in terms of possessions per game. Furthermore, any advantage that higher tempo teams might seem to receive gets negated when we consider that successful possession percentage is on average 50% meaning that it shouldn’t lead to more surplus possessions. For the players that are over 50%, then a slight advantage arises but this is no different than players who are ballhogs, or play more minutes. We assume that players who play a faster tempo deal with lower quality shots, and apparent ballhogs are in fact so, due to their teams reliance on them – therefore at the end of the day, more possessions come at a price, and we can safely discard these discrepancies while still retaining a true view of the top offensive players.  

  

As most of us know (well most of us outside of the Golden State Warriors), in basketball offense is only half of the game. Therefore defense will take center stage in part 2 as we similarly rank the top players who help prevent opponents from creating sucessful possessions.  

Kobe’s Worth

Tuesday, November 6th, 2007

kobe4.jpg

Couple of months ago, at the peak of the Kobe public meltdown, I wrote an article trying to make people understand Kobe, explaining his story with a bit more compassion. While there are still those that hate him, people I believe have grown to sympathize with him more, largely thanks to a Lakers organization that serves to be the ‘larger of the two evils’. Today, the Kobe debate has shifted to something else, and for once it is actually basketball related. The question today: “Is Kobe worth it?”.

Ever since Dr. Buss came out in preseason and revealed that Kobe was tradable, I have expected every single team in the league to at least make an offer. You don’t Lose Weight Exercise/”>Lose Weight Exercise anything by trying right? Instead, weeks have passed and there has yet to be a serious offer on the table. The main reasons for this I thought to be: Kobe’s large contract and the salary cap, his trade kicker and the no trade clause, and Kobe’s desire to play for a championship caliber team. However, Chad Ford over at ESPN tells us that it’s in fact been many different reasons why the Lakers have yet to receive a worthwhile offer. Apparently, teams doubt whether he is actually worth it! Here are the 3 real concerns, according to Ford, that are bothering teams considering acquiring Kobe.

 

Question 1: Does Kobe have too much mileage?

  

The first question teams seem to have on their mind is how many more competitive seasons does Kobe still have in him. In Ford’s article, comparisons are made to a vehicle and the ‘mileage’ on Kobe’s legs, and similarities are drawn between Mourning/Cassel/Webber’s minutes with KB24’s – but I don’t buy into any of this crap. First of all, what I see with my eyes today is that Kobe is in the best shape of his life. He plays defense like a rookie trying to get some burn, and still lights it up as reliably as General Electric. He is one of the hardest working athletes…ever….and it is quite hilarious to compare him to Sam Cassell. The number of minutes played in the league is also not completely indicative since he skipped through 4 years of grueling college practices. Besides, Jordan was much more reliant on his athleticism as a youngster than Kobe has been and even so Jordan could adjust with older age. Kobe is absolutely deadly from beyond the arc, on pull up jumpers, or in the post and losing a couple of inches off his vertical will not limit his abilities as much as people might think. At this point in time, anyone short of cowardly managers and heavy statisticians wouldn’t dare argue that Kobe is fragile physically.

Question 2: Is Kobe really the best player in the NBA? 

Again, a bunch of cleverly cooked up stats is thrown at us in attempts to re evaluate our opinion on Kobe’s worth. I’ve already expressed in other posts how much I hate stats when we rely on it too much, and this is exactly what has happened in Chad Ford’s article. Player efficiency ratings, plus or minus ratings, clutch time stats, playoff success in recent years – all this junk I’ve heard of before and as I’ve done before I urge anyone with half a brain to not read to deeply into these stats. I would like to ask this John Hollinger or anyone else following stats religiously whether they includes the following elements into their formulas: quality of players on the team and double/triple teams on the players in question. Say Dirk is put into a team with four 13 year old kids this season, would he still have those numbers, would he still have that clutch ability with the whole defense shadowing him, would he still take his team to the finals. My example is exaggerated but you should understand that certain factors differ across teams and players’ situation can’t be compared with mere stats. Let’s please stop this stats attack, it’s new age sports propaganda, that’s all it is. We have all seen Kobe make countless fade-away cross-court passes out of a double team to a wide open teammate who ends up bricking the shot. We’ve seen Kwame travel more often than the Globe-Trotters. We’ve seen Smush Parker put up enough bricks to build another Great Wall. Do these stats not have any worth? 

Question 3: Is Kobe a winner?

Hmm ok lets think about it for a second. Kobe has three rings. LeBron, Nowitzki, Wade, Arenas, Pierce, T-Mac, Garnett, Nash, Kidd, Iverson, Carter have how many? 1. Using my Oytun Championship Efficiency Rating © , I calculate Kobe to be three times better than all of those players combined. If you bring up the fact that he had Shaq on his team then you would be a complete hypocrite because you say his team was too good when he did win, and now that he isn’t winning you don’t consider that his team isn’t good enough. The double-standards rack up faster than Duncan’s double-doubles when Kobe Bryant is concerned.

Question 4: Is Kobe worth it?

At the end of the day, teams need to think what their priorities are. Today there are only a handful of teams that can seriously challenge that title: Dallas, Phoenix, Houston, San Antonio, Detroit, Boston. Other teams that claim they can be champions are just lying to themselves. So every other team should theoretically be building towards a championship. You got some teams that build from scratch because that is the only way they can, and then you got the rest who probably need to be on the verge of a championship in a couple of years or they will need to start over themselves. Teams such as Chicago and Washington have a chance to become immediate contenders if they add Kobe to their team. So why not go for it? Well as Chad expressed, it is always safer to make a non move than make a move. Also truth be told, becoming Champions isn’t something most of the NBA teams think about…realistically at least. They rather fill up seats, and have promising young players than risk it all for a small shot at the championship. This is not a league full of teams that live and die by wins and championships. This is the entertainment league where your image in the papers is just as important as your strength on the court.

Essentially, I believe these teams are trying to create excuses for themselves so they don’t have to deal with the Kobe headache, they can’t seriously be doubting Kobe’s worth can they? There is also a possibility that this ESPN article was a result of clever manipulation by team managers to reduce Kobe’s trading value. Whatever the reason, it is clear that Kobe still has a lot to prove. In fact, it is no question that after several NBA titles, consecutive scoring titles, All-NBA, All-Star, All-Defensive Team awards– it is in fact these last remaining years of his career that will define who he really is. Is he really the next Michael Jordan, or will he be yet another one of the wanabe’s that just couldn’t live up to the expectations. Only the future will reveal Kobe’s true worth.

Denied! : “Bloggers just aren’t journalists” by Chris McCosky

Monday, November 5th, 2007

Denied! is a regular special feature that will see me take an article/action/story and let the culprit in question know exactly why they are wrong.

This week I will be targeting all-mighty journalist Chris McCosky from the Detroit News and his recent elitist article condemning (practically) all bloggers around the world. Essentially what he says is annoying him is that bloggers are discrediting the media, but personally I believe his discontent runs deeper than that.

His opening argument criticizing the legitimacy of bloggers is as follows:

“Journalism employs trained professionals. We actually have to go to school for this stuff.”

Truth be told, I completely sympathize with this statement. Not because it’s a valid argument towards his case, but because I felt the exact same way as a Business graduate looking for a marketing job. I realized that anyone and everyone is encouraged to apply for these positions and that my Business degree with a focus on Marketing gave me no edge at all. At first I was bitter and ranted on and on just like Chris did here in his article. After stopping to think about it for a second, I realized that perhaps my degree didn’t really give me an edge and in fact there could be countless non ‘marketers’ that would be much better at the job than I. The first step to recovery in this situation of feeling a decline in the value of your degree and profession is admitting the problem.

Which leads me to step number two: doing something about the problem. Besides perhaps having a linguistic edge over us non-journalist, you must realize that your sole added value as a writer is as you point out, “We actually talk to, in person, the people we write about.” So that’s what you should stick to, and sleep safe knowing that us bloggers will probably never have access to these sources. Journalists provide factual data, and bloggers take it and play with it how they like. That’s how the game works, welcome to the 21st century. If people weren’t interested in sports enough to share their opinions and blog about them, there would certainly be a decrease in the amount of newspapers bought or sites visited. This would essentially lead to a decrease in revenue of media entities, and would lead to some fully trained journalists such as Chris to be out of work. It is in nobody’s interest to mess with the fragile ecosystem in place.

What ecosystem do I speak of? Let’s make it very clear that the majority of bloggers do not make a living out of blogging. I would say it’s on the other side of the spectrum if you consider ‘journalists’. Hence it is completely wrong to look at the two as rival products, in fact they are complementary to each other’s success. As I mentioned, bloggers rely on journalists to do all the ‘hard work’ for them. If there was no hard work for bloggers to ‘copy and paste’, it is then that the journalists should feel threatened. But to take the current situation and publicly belittle bloggers who just blog as hobby is very irresponsible. You are biting the hand that feeds you.

I don’t know what kind of insecurities has rattled Chris’ cage but it is clear that he would like professional journalists such as himself to be given much more credit – and this I can’t say I support. Since journalists rely on constant stories and a readerbase to make a living, their‘work’ ends up being far less reliable than Chris makes it out to be. As Chris brought up himself, ESPN and every other news company of some sort will generate story after story just to keep readers coming to their site. You will have: made up trade rumours, stories that are misleading, reporting news that should be left personal, over dramatizing events, and making more out of a story than what you must have been taught in ‘Journalism Ethics 101′. I think anyone who follows sports cLose Weight Exercise/”>Lose Weight Exercisely will know what I am talking about. Furthermore, every story needs to have a catch or keep readers interested, which results in twisting the real story for their personal point. Imagine a tabloid magazine reporting dull news – this is a recipe for disaster. Sports media similarly needs to keep filling the headlines that will sell papers and make web surfers click the story. A blogger on the other hand has no quota to fill and no credentials to make up a story, so at least what he reports is what he genuinely feels. No bosses to worry about, no sportstars he has to keep happy to get more interviews, and no readerbase that he has to keep hooked. Yes, there will be instances where an irresponsible blogger will try to draw all eyes on him, but it is not the standard that should be applied to the other millions of bloggers out there. Much like there are bad journalists, there are bad bloggers.

You must also try to understand that just because you have a journalism degree, it doesn’t mean that you know more about sports than us bloggers sitting at home in the basement in their pijamas. In fact, those who end up blogging about sports for no revenue must be die-hard sports fans – wouldn’t you agree?

It is time to get off your high horse and accept bloggers and blogging, because it is not a phenomenon that will pass with time. People from the dawn of time have enjoyed communication, sharing thoughts and ideas and feeling part of a community. So get use to us, and if anything step up your journalism work so us bloggers won’t have a chance to ‘discredit’ your reporting – as I have just done here today.

Open Letter to Gilbert Arenas

Sunday, November 4th, 2007

Dear Gilbert,

I want to start off by letting you know I’ve been a big fan over the past couple of years. Your personality, attitude, outspoken demeanor, the underdog status, and your exciting style of play has resulted in millions of people declaring you as their favorite player, hero, icon – and I use to be one of them. However, the article I read over at CNNSI has led me to seriously question what you’re really about.

Over the past 3 seasons (your best ones), you’ve averaged around 27 5 4. No one can deny these are great numbers even considering the sup-optimal field goal percentages. However, it seems like you are too caught up on the numbers game. In fact it is clear that you are – your jersey number being a nightmare stat that serves as the root of your hunger to succeed. Remember when you wanted to take revenge on the USA team coaches? Your main focus was to drop 50 on them, no mention of a victory anywhere. There have been small signs here and there of caring more about stats and fame than wins, but these were the Gilbert type actions that didn’t hurt anybody and everyone enjoyed the laughs.

 

Recently however, it seems like it has taken a whole new life form. You are back from injury, you perhaps haven’t gotten the hype or attention you were looking for and as a result your actions have paralleled that of an attention seeking whore – no offense. The all-confident claims of ruining Boston’s season opening party was clearly an attempt to steal some attention from the Boston hype that’s got the whole league zoned in. You even realized yourself prior to the game it might have been an overstatement and tried to backtrack in your blog– but the damage had be done and was inflicted upon yourself and your Wizards on gameday. This was still okay in my book, because you were still the hype creating, excitement generating, outspoken guy that everyone loved to follow, but I think in your recent interview with SI, you clearly crossed the line.

In the interview, what you essentially did is: put yourself ahead of today’s leading proven players with some conveniently chosen and flawed stats, and criticized not only one of this generations greatest players (Kobe) but also of the past generation (Isiah Thomas). You went ahead and threw the Wizards team bus under your personal steamroller.

“If I’m doing what I do and I lead this team to 50-something wins, that’s MVP. Hands Down.”

You must not hold your team in high regards if you think getting your team 50 wins is a spectacular achievement from your part. Getting Jamison and Butler alot of points per game seems to be a particularly proud achievement of yours. You go on saying how you make others score more and admit its because of having more possessions and playing a faster tempo game. Let me ask you; Do you think anyone cares if all three of you score 50 each but on the other hand because of the fast tempo your opponents score 200 points and they end up beating you. Do you understand that stats are not the final word on a players’ quality? Do you realize that you’re playing the game to win games and championships, and stats are just mere details on that journey? You are speaking way out of line, and let me give you some stats because that is all you seem to comprehend at the moment.  

Lets look at previous cases; Jerry Stackhouse averaged 30 5 4 in 2000-2001 followed by 24 5 4 the next season. Ricky Davis has been averaging around 20 5 4 for how many years now. Did they ask for any MVP considerations? You want to talk about point guards that can score, and get their teammates involved? Ok, lets forget for a second that you claimed yourself to be better than 2 time champion Isiah Thomas and consider these current day players: Tony Parker, Baron Davis, Chauncey Billups, Deron Williams. All these players have had playoff success, can score at will, AND get their players involved. (Parker plays with Ginobili and Duncan who average cLose Weight Exercise/”>Lose Weight Exercise to 20 each, Baron Davis can get the whole starting 5 in the 20 zone, Chauncey Billups won a title scoring and distributing at the same time, Deron Williams has shown signs that he can do the same.) Chris Paul, Jason Kidd, Marbury etc… As you can see the list is long and they almost all pass your all worthy benchmark of including others in the offense while scoring prolifically. You solely take the examples of Wade, LeBron, and Kobe which frankly put, is not a category you belong in… yet. Wade carried his team to a title, LeBron has taken his mediocre team to the Finals, and Kobe has three rings. What have you got besides a Halo Team and 20 sneakers?

I hate to write this but I just feel like you’ve been straying away from your usual self, and proper fans don’t let their heroes stray like that. You criticize Kobe for wanting to get out when you should be the exact person who understands his situation. You talk about not receiving enough praise concerning how important of a player you are, at a time when your team sits at 0-3 and clearly you need more work on that J.

 

Please, Gilbert, don’t forget what made you who you are today. That struggle to overcome the toughest of obstacles, that hunger to succeed at all costs, that relentless ethic of wanting to show how good you are rather than talk it. Ironically it is again that 0 on your jersey you should be fighting for, because at the end of your career if you don’t win a championship, that ‘0’ will have a whole new meaning.

 

Sincerely,

A Loyal Fan
