eBA sketball Statistics Case Study: About Basketball Rebounds

Basketball Statistics eBA Case Study
Different Situations in a Basketball Rebound... Case Study

"... A missed shot comes off the rim and bounces along the floor. A1 is in position to pick up the ball, but B5 gains control. However, B5 fouls A1...

• case a) before either can touch the ball, or
• case b) as B5 is the first to touch the ball, or
• case c) after B5 is first to gain control of the ball, or
• case d) after A1 is first to touch the ball.

What is the statistical registration according to the eBA Basketball Statistics Analysis System in each one of the given situations, including the type of the registration ( forced or unforced TO; good or bad foul; close, long, disputed or undisputed rebound, etc.) ... ?"

Conclusion:
eBA System Statistics Fundamentals:
A player should be credited with a rebound only if the player earned that rebound before the ball was dead. What happened after the ball became dead and what would have happened if the ball had not become dead might be different.

The statistician should not attempt to decide what would have happened, but should decide only what did happen. However, if there is doubt about player control, the statistician may assume that there was control.

Sometimes there is doubt about whether a player has gained control of the ball before a certain act takes place. In such cases, the statistician should use the following guidelines.
• (a) If the statistician feels there was a possibility of player control, then the play shall be treated as though there was player control.
• (b) If the statistician feels there definitely was not a possibility of player control, then it shall be treated as though there was no player control.

eBA Basketball Statistical Tracking:

• In (a) the ball became dead when the foul was committed. Charge B5 with a BAD Personal Foul and credit Team A with a LONG UNDISPUTED Dead-ball Offensive Rebound.

• In (b) if B5 gained control before the foul, the official will have indicated that the foul was a player-control foul and B5 would be credited with an individual LONG DISPUTED Defensive Rebound and charged with a FORCED Turnover.

Urban Meyer and Coachtube

If there is no indication of player control, then credit Team A with a LONG DISPUTED Dead-ball Offensive Rebound.

• In (c) credit B5 with an individual LONG DISPUTED Def Rebound and charge him or her with an UNFORCED turnover

• In (d) if the statistician thinks that A1 possibly had control before the foul, credit A1 with an individual LONG DISPUTED Off Rebound.

If the statistician thinks that A1 definitely did not have control, credit Team A with a LONG UNDISPUTED Dead-ball Offensive Rebound.

About the Efficiency in Different Possession Start Cases and the Fast Bbreak
in our Basketball Stats Tracking Referred Questions & Basketball Statistics Video Case Study

Basketball Statistics Tracking Referred Questions:
About the Efficiency in Different Possession Start Cases and the Fast Break

Basketball Tracking Stats Referred Questions
"... When exactly - within how many seconds - we have a 'fast break' ?

Fast break points is a stat that TV broadcasters always talk about - saying how some team ranks in it on the season.

Is this stat collected into season rankings in the eBA Basketball Statistics
System
?
And what is its relationship with the efficiency in different possession start cases ? ..."

As was explained in another post, when we explained how to record the plays according the 24 seconds rule, the eBA Basketball Statistics System tracks this stats into season rankings.

From the >eBA ONLINE Clinic we know that the system tracks the plays according to the shooting clock, within 4 - 8- 16 - 20 and 24 seconds. Therefore, the fast breaks are the plays recorded in the first 4/5 seconds of the shooting clock, subtracting out offensive-rebound putbacks.

Presently in the Saturday's eBA Annual Clinic we are discussing about a norm related to the number of passes in a fast break.

Different Basketball Possession Start Cases and the Fast Break
Photograph: from Flickr

About the Basketball Efficiency in Different Possession Start Cases:
Here I post some comments on the results included in this post: Efficiency in Different Possession Start Cases.

The complete analysis is included in my exposition about "Possessions" in the eBA ONLINE Clinics:

~ The manner your opponent scores (2p, 3p or FT) does not have a major effect upon your efficiency;

~ Most teams performs better when the possession starts with a defensive rebound after an opponent missed 2p FG;

~ It's easier to put back the ball when an offensive rebound follows a 2 point shot than after a 3-pointer;

~ Good defense makes better team's offense by approximately 5% and good offense improves defense in the same way;

~ A steal is a great offensive tool, more than an offensive rebound;

~ The high efficiency in regards to steals is reasonable because a steal leads to a fast break which is one the most efficient offensive opportunities as well as an offensive rebound;

~ The biggest difference between NBA and European results is efficiency after non-steal turnovers probably because in the NBA an steal is always credited if the ball stays live, which is not always the case in European stats: the eBA Basketball Statistics Analysis System records the steals according to the NBA conception;

~ It is harder to take an offensive rebound after a 3p missed than after a 2p missed;

~ One factor that makes bigger the average efficiency after Free Throws is that, because of the team foul penalty, there are more Free Throws near the end of a quarter;

~ The penalty situation also helps to increase efficiency: the net result is a higher average for Free Throws cases than it should be.


See in our forums the 'technical foul tracking' topics and the exposition "Basketball Fouls Tracking & Analysis" at eBA ONLINE.

"... 4 second to the end, 55:52 the whites 'Patriots' 3 points back and with the ball, only a 3-points conversion should send the game to an OT. But... after the field goal made apparently for 3 point, one official signals a three point made and another official run from the left of the screen to call WHAT HE SAW: the player slightly step on the three points line, what makes the final game score to 55:54 against the Patriots, and... no OT !...

Weekly Reflexions on Basketball Statistics:
About the Efficiency in Different Basketball Possession Start Cases

Basketball Statistician's Sunday's Reflexions
In the eBA Basketball Statistics Creative Analysis System there is a study on the average offensive efficiency in different possession start cases. Is was made by Prof. using data from play-by-plays of 2000 games of the Euroleague from 1988.

The research was presented in the still finished eBA Basketball Statistics Clinics, and give us, among a lot of other analysis elements, the order of the starting of the possessions ordered from highest to lowest offensive efficiency:

01 - Steal,

02 - Offensive Rebound after 2p FG missed,

03 - Offensive Rebound after 3p FG missed,

04 - Defensive Rebound after 2p FG missed,

05 - Opponent non-steal turnover,

06 - Defensive Rebound after 3p FG missed,

07 - FT made,

08 - 2p FG made,

09 - 3p FG made,

10 - Start of quarter,

11 - Defensive Rebound after FT missed.

About the Basketball Game Pace and the Turnovers:
From the same research at eBA Basketball Statistics Creative Analysis System about the influence of the 'game pace' on the 'turnover ratios' of individual players, we can infer:

...there is a connected increase in the number of TO due to pace: as pace increases, players/teams get more TO/Min and TO/G.

Therefore we may suppose the sooner your team shoots the ball, the less probably you have a chance for a TO. Or that time of possession is what's mutually related to TO.

But, while the presumption is that a faster pace means more errors and more turnovers, if you shoot the ball before you pass it, you turn the ball over less.

So, generally, turnover rates do not become larger with quicker pace.

In this case, you wouldn't expect players' turnover rates to vary too much.

Many other factors could have an effect upon TO rates/possession used or touch year to year:

 • different players in the same organization

 • modifications to an organization that does not suit a particular player's style

 • injuries (players depending on first step with knee/ankle injuries, and injured wrist, etc.) ...

Basketball Block Shot Analysis & Statistics Tracking:
With or Without Ball Control is the Question!

Basketball Block Shot Analysis & Statistics Tracking:
With or Without Ball Control is the Question!

The answer was:
A1 goes up for a shot under the basket and the defensive player B2 knocks the ball in the hands of the shooter while they are both in the air, and there is no case of foul. A1 then let the ball fall to the ground before landing back on the court, gathers the ball up and makes a basket.

What is the call for the game and the statistical tracking in case of turnover?

Celtics small forward Paul Pierce has his shot blocked by Charlotte Bobcats power forward Tyrus Thomas during their NBA basketball game in Charlotte, North Carolina. Photo: REUTERS/Chris Keane

By definition (see our eBA Basketball Statistics Analysis Encyclopedia ) a blocked shot occurs when a defensive player successfully and legally deflects a shot from an offensive player by touching and rejecting the ball on its way to the basket, and before it has reached its highest point, in order to prevent from a field goal.

In order to be a legal action, the  block must occur while the shot is travelling upward. It it is heading downward when the defender hits it, it is ruled a goaltending and counts as a made basket.

We have an altered shot when a blocker changes the shooter shot causing the shooter to miss the basket.

Opponents' field goal percentage vary widely depending on which interior defender is close to the basket. Milwaukee's Larry Sanders is one of the most effective interior defenders in the league: opponents struggle to score when he is near the basket. This not the case with Boston Celtics' David Lee: when he is close to the basket, opponents score at very high efficiencies. (Click on the picture to read the full article by Adam E. Gallagher from  Tropics of Meta). In this Image: by Adam E. Gallagher from  Tropics of Meta presented by eBA Basketball Statistics Analysis Group.

If the ball is knocked out of the offensive players hands while they are in mid air, then they regain control once they have landed, this is legal.

If the ball is forced out during the time that the player is in the air, the player regains control (while in the air) and lands, it is a travel.
eBA Basketball Statistical Tracking=
Forced Turnover

If the offensive player returns to the floor, holding the ball, and the ball has never left his hands, one of two things are possible:

1) if the defensive player has only one hand on the ball, it is a travel against the offensive player.
eBA Basketball Statistical Tracking=
Forced Turnover.

Coachtube and Tom Izzo

2) if the defensive player has both hands on the ball it is a jump ball which will be resolved according with the alternate possession rule

About the Basketball Possessions Ending in TO & the True Percentage of Team Poss Used
& the Basketball Training Video in our Monday's Reflexions on Basketball Statistics

Reflexions on Basketball Statistics:
15,97% of the Basketball Possessions End in TO

Basketball Statistician's Monday's Reflexions
How we perform the analysis of one team´s turnovers in relation with other team, let say the next opponent at the next game ?

If a team averages 15 turnovers a game, and the next opponent is a team that forces 15 turnovers a game, is it possible to assume that there will be 15 turnovers for that game ?

Or... we must take the league average as the basic unit to analyze this data: if the league average for turnovers is 16.4 that´s means that each team turnover rate is 109,33% compared to the league...

During the eBA Basketball Statistics Tracking Clinics I expressed my opinion that 'exclusive ratings' and 'scientific formulas' employ only a lacking minimum of the significantly important statistics: turnovers per possession and Defensive turnovers per possession; games won and games lost; etc.

But all other information as playoff game vs meaningless garbage time, recent injuries, possible matchup advantages, etc. (see the thread about eBA System Non Standard Statistics ) are disregarded.

Homecourt advantage is usually disregarded too, (see this thread about Home & Road Stats: differences ) meanwhile the Game Analysis & Scouting takes in account every one of this categories, and much more.

You can reach to the answer to your question by a different way: express the team's turnover proclivity in terms of the proportion of possessions that end in turnover - according to the eBA Basketball Statistics Analysis System Archives: around the 15,97% of the possessions end in turnover.

Los Angeles Lakers shooting guard Kobe Bryant (24), against a 1 vs 4 defense !, has his shot blocked by Chicago Bulls small forward Luol Deng (9) in the final seconds of the second half of their NBA basketball game in Los Angeles on December 25, 2011. The Bulls won 88 to 87. In this UPI photograph by Lori Shepler from Dalje.com presented by #eBAStatsGroup #BasketballStatistics Analysis .
Photograph: Dalje.com

About the true percentage of team possessions used:
We know that the 'Usage Rate' is the formula to determine how many possessions a player uses. But which is its significance ?.

If a player keep an account of a high usage of possessions that means he is the one who has the greatest effect of on how well the team performs ?

So if that team is great and he leads the league in 'usage rate' would that make him the best player in the game ?

The team's offense is a measure of how well its high-usage players are shooting: in a good offense, the high-usage player is usually effective; in a bad offense, the high-usage player is usually ineffective.

The eBA Basketball Statistics Analysis System doesn't applies "Usage Rate" because it's not really measures possessions and doesn't really have anything to do with a player's defense.

We apply a stat that really measures usage:the percentage of team possessions used while on the floor.

Surely a player using up to 25-30% of team possessions is going to have a big effect on how well the offense performs, good or bad; by contrast, teams can get the best of low-efficiency, high-usage players and, rarely but possible, however have some decent offense.

eBA Encyclopedia Statistics Terminology: Parameter in Statistics

Permalink 02:55:41, Categories: Statistics, Statisticians & Roles, Terminology  

eBA Encyclopedia Statistics Terminology: Parameter

eBA Encyclopedia Statistics Terminology
In mathematics, statistics, and the mathematical sciences, parameters are quantities that define certain characteristics of systems or functions.

When evaluating the function over a domain or determining the response of the system over a period of time, the independent variables are modulated, while the parameters are held constant.
The function or system may then be reevaluated or reprocessed with different parameters, to give a function or system with different behavior.

statistical parameter


Loosely speaking, then, parameters are constants in a narrow context but are variables in a larger context.

Moreover, whether a quantity is a parameter or a variable is generally determined by its role in a particular system or function, rather than by anything intrinsic to the quantity.

In non-technical contexts or in jargon, parameter may also simply be a synonym for criterion.

Read More more details about this definition and another statistical terms at our new Statistics Terminology Glossary.

Reflexions on Basetball Statistics: The Basketball Defensive Rebound Efficiency

Reflexions on Basketball Statistics:
Some Reflexions about the Basketball Defensive Rebound Efficiency

basketball 24 Seconds Statistics
"... Talking about turnovers, for example, you might hear someone say, "Our team perpetrated 18 turnovers. That's not very good."

It might not be, but you'd have to know more about the way the game was played to reach that conclusion. 18 turnovers against a slow-down team would be awful. 18 turnovers against  a quick-pace squad would be accomplishable. ..."

"... There's a stat called 'defensive rebound efficiency' that is  used in the eBA Basketball Statistics Creative Analysis System -- it measures the amount of defensive rebounds taken down from missed shots.

Some Reflexions about the Basketball Defensive Rebound Efficiency
Photograph: The LLaBB

There's a similar idea we apply in eBA Basketball Statistics Creative Analysis System as 'offensive rebound efficiency', which simply measures the amount of available offensive rebounds that a team gather.

One area where that stat breaks down, however, is that it's hard to take free throws into account just by looking at the box score because there's no way to know which missed shots could result in an offensive rebound.

This is Kawhi Leonard’s defensive shot chart for the 2013-14 season. Think of it as the inverse of a conventional shot chart: It reflects the shooting behavior of players when Paul was defending them. The sizes of the symbols on the chart correspond to shot frequency; the color of the symbols represents shot efficiency. These defensive shot charts do a good job of showing the relevance of individual defenders. Players like Leonard reduce the effectiveness of whoever they’re guarding.

About the Basketball 'Assist-Turnover Ratio'
& the Basketball Training Video in our Weekly Reflexions on Basketball Statistics

Reflexions on Basketball Statistics:
About the Basketball 'Assist-Turnover Ratio'

Basketball Statistician's Sunday's Reflexions
Reading the 'assist-turnover ratio' from the box-scores, where a player's Ast/TO ratio start to help his team's offensive effectiveness ?

It is clear this level must would be higher for a point guard, but which are the statistical levels ?

Both statistics categories assists and turnovers matter when we note at the European Basketball eBA Archives that 7 of the top 10 AS/TO players are on playoffs teams and of course it does have a positive effect.

 • turnovers are a four factor category according to Dean Oliver's "Basketball on Paper" book;

 • assists suggest good passing and have positive impact on at least 2 of the other three (FG% and FT/FG);

Under the defensive pression of Bryant Mbamalu, freshman guard Denzel Valentine turns the ball over during the game against Louisiana-Lafayette Ragin' Cajuns on Nov. 25, 2012, at Breslin Center. The Spartans beat the Ragin’ Cajuns 60-63. Photograph by Natalie Kolb / The State News

 • TO do not help the offense, but Pts / Reb / Ast do;

 • assists have positive impact on offensive rebounding if the good passes creates a need for help defense;

 • the Basketball Statistics Analysis System separates out 'TO resulting from passes' in our calculations;

 • assists also allow some of the players to focus more on rebounding than looking for their shot;

 • from the eBA Archives top 5 teams on raw assists played the playoffs but 3 of the bottom 5 played too;

 • assists are not one of the four factors categories according to Dean Oliver's "Basketball on Paper" book;

 • as you can see below, the results are different if the PG is also a shooter and/or rebounder - all this things create turnover opportunities-, than if he just brings the ball up and passes;

 • you can play with the following numbers taking into account that this is only a new eBA Research and the break-even points may very well be different for each position:

Forget passing, which player is the best decision maker?3 In this image, Leonard’s shot probability is tied for the most likely outcome, even though by expected possession value it is his worst option; passing to anyone would be better. And these numbers can be tailored to individual players! With substantial sample sizes for individual players over the course of thousands of possessions, we do not have to settle for 'Shooters make X percent of open corner threes', we can specify that 'Player Y makes Z percent of open corner threes'. Which point guard best understands his teammates’ strengths and weaknesses, the differences between the starters and the subs, etc? Which big man has the most added value when getting the ball at the post?  <br />

Work your defender to get him out of position and finish ice-cold with the unblockable running hook shot.

1. Post up Establish contact with the defender in your back. Before you receive the pass make sure that you are in a low and powerful position to keep your balance.

2. Fake baseline Spin to the right to fake out your defender. When he shifts, youve got yourself some space to move.

3. Attack middle Now that you have your defender out of the way, turn round and attack the basket from the centre.

4. Running hook As you approach the basket, use your left arm and shoulder to protect the ball from any block attempts. Then as you take the shot; use your fingertips for extra control and shoot smoothly over your defender into the basket.

About Free Throws Line Up - Rules Differences & Statistics Tracking
& the Basketball Training Video in our Weekly Reflexions on Basketball Statistics

Reflexions on Basketball Statistics:
Free Throws Line Up - Rules Differences & Statistics Tracking

Basketball Statistician's Sunday's Reflexions
At NF - National Federation (U.S. High School):
a- teams are entitled to alternating spots on the lane, with the opponents of the free shooter getting the spots closest to the basket.
b- as many as 8 players can be on the lane (4 each side), and you could have 5 from one team, as any vacant spot can be filled by an opponent.

At NCAA, NBA, FIBA:
a- teams are entitled to alternating spots on the lane, with the opponents of the free shooter getting the spots closest to the basket.
b- only a maximum of 5 players may be on the lane: 3 opponents of the shooter and 2 teammates.

At NBA:
c- the lowest 4 spots MUST be filled on the final throw.

At FIBA:
c- any of the spots may be empty, but must remain empty if the team entitled to them does not fill it.

At NF, NCAA, FIBA:
d- players not in marked lane spots, must remain outside the 3 point arc and behind the free throw line extended until the ball strikes the ring.

At NBA:
d- this part of the rule is somewhat more liberal.

Basketball fans have made an artwork out of distracting the players at free throws time !

Free throws are an organised process, for the statistician too. Let us see something about the basketball statistics tracking in this case. Really, is the shoot we have all the time to record data. The shooter takes his place behind the free throw line (4.5 metres or 15 feet from the basket). All other players must stand in their correct places until the ball leaves the shooter's hands:

The number of players allowed by the rule - according the introduction - lines up along the sides of the restricted area ( keyhole, paint, lane ). These players are normally the ones that rebound the ball. Three or four line up on one side and two or four on the other. In all the rules, a defensive player always takes the place closest to the basket.

The remaining players, must remain behind the three point line and the free throw line extended (an imaginary line extended from the free throw line in both directions to the sidelines).

Leaving their designated places before the ball leaves the shooter's hands, interfering with the ball, and (for the defensive team only) attempting to put off the shooter, are all violations. In addition, the shooter must release the ball within five seconds (ten in the NBA) and must not step on or over the free throw line until the ball touches the ring.

- A violation by the shooter cancels the free throw and the statistician records a missed free throw and a team rebound for the opponents, in case of last free throw;

- a violation by the defensive team results in a substitute free throw if the shooter missed and no stats tracking in the possessions counting, only at the play-by-play relate - see eBA Basketball Statistics Creative Analysis System;

- a violation by the offensive team or a shot that completely misses the ring and backboard results in the loss of possession to the defensive team ( only if it is on the last free throw ), the statistician records a missed last free-throw and a defensive team rebound on FT for the defensive team.

Weekly Reflexions on Basketball Statistics: Who owns the basketball team statistical data?

Weekly Reflexions on Basketball Statistics:
Who owns the basketball team statistical data?

Basketball Statistician's Sunday's Reflexions
When the statistician ends his work and send the game analysis report: is the statistician owed a right to use the data for publication purposes ?

First of all, at the early stages of the season, and in order to eliminate doubt from the beginning of the statistical employment, a document of agreement between the basketball team's manager and the statistician certainly would make clear and more comprehensible each party's respective obligatory preconditions and rights.

If the agreement involves a total permission, we´ll have no any problems.

Now, when the statistician works for a basketball team, data ownership clearly belongs to them.

If it was agreed at the pre-season and contractually that the basketball team owns the data, and the statistician is partially allowed to use the data for publication purposes, obviously there is an obligation to hide the basketball team's and institution's identities to protect their rights to anonymity in accordance with this right of limited use.

In any case, the head coach and the manager should be informed of such intended use of data and supplied with a copy of the final written research.
