An "Advanced Basketball Statistic" That Makes Sense

"...  It should be obvious that neither field goal percentage nor an "advanced basketball statistic" like true shooting percentage provide a complete description of a player's shooting ability and/or scoring prowess; a player who posts gaudy numbers in one or both of those categories may be a limited offensive contributor who can only score effectively in a very specific role (i.e., a big man who can only convert from point blank range or a slow-footed perimeter player who can only make spot up jumpers).  ..."

"... A player's offensive efficiency can only be accurately determined by examining his ability to create shots for himself and his teammates, his ability to score from a variety of areas on the court and his ability to draw double teams that can break down the opposing defense. Such evaluations can only be made by an informed observer who watches the sport with an objective eye. ..."

"...  A player who shoots .600 from the field but cannot make a shot outside of the paint and is easily defended one on one is not nearly as valuable as a player who shoots .450 from the field but can score from anywhere on the court and must be double-teamed.

Is there a way to reasonably compare two players who have such divergent skill sets? Kirk Goldsberry's solution to this problem is a new statistic that he and fellow Michigan State professor Ashton Shortridge devised: ShotScore ranks every NBA player's shooting prowess based on the relative difficulty of each shot that he took; Goldsberry and Shortridge determined the average NBA field goal percentage from every spot on the floor, compared the average percentages to each player's percentages from those spots on the floor and then expressed the results in terms of actual points scored versus expected points. ..."

Last year, NBA players took just about 200,000 shots. The league’s collective shot chart reveals the spatial nature of the NBA’s average shooting efficiency. By itself, the chart shows the stark relationship between court space and expected points per shot — that’s why 3-point shots are rapidly increasing in popularity while midrange shots are diminishing.

"... There is little doubt that ShotScore is a more precise measurement of a player's shooting efficiency than scoring average and/or field goal percentage.

The usefulness of ShotScore and the measured tone of Goldsberry's writing are a welcome contribution to basketball theory--and a marked contrast to the way that far too many "stat gurus" make arrogant and bold declarations that are unsupported by facts/objective observations.

However, there are some potential drawbacks to ShotScore: (1) it relies heavily on the completeness and accuracy of play by play data regarding shot locations and
(2) a person must have access to a tremendous amount of data in order to calculate a player's ShotScore. ..."

"... ShotScore could be very useful for general managers and coaches but it will be difficult for it to become a mainstream statistic unless/until the accuracy of the play by play data can be objectively proven and unless/until it becomes easier to compute each player's ShotScore; during a game, an informed observer can note the areas in which a player is effective and can instantly calculate his field goal percentage to get a "quick and dirty" estimate of his overall efficiency but there is no way that such an observer can instantly compute a ShotScore unless/until the NBA provides such data in real time (which could perhaps happen at some point). ..."

Riccardo Muti: WE ARE SMALL BEFORE GOD !


The Master Lesson by Muti

This video which belongs to 'Musical America' was recorded during the award ceremony to the musician of the year of the publication 'Musical America' in December 2009. Neapolitan director Riccardo Muti makes a memorable speech about what it means to conduct an orchestra ... he means really direct... It has hilarious moments (apparently reaches a great comic gag) and ends with an exciting definitión about your job, a job he describes as "the world's most difficult profession.

• Más Triples y Largos Sobre el Final
• More Three-pointers & Longrange on the End


( for English Translation: See Below )

Lógicamente, para contestar a su pregunta y dar por iniciada la discusión, todo depende de la situación en el partido: si su equipo está perdiendo por pocos puntos y cada punto aparece como más importantes, entonces  más triples y lanzamientos de larga distancia serán tomados...

Nosotros realizamos para nuestro Sistema eBA de Análisis Creativo de las Estadísticas del Baloncesto un análisis de las frecuencias de lanzamiento cuando quedan más de dos minutos por jugar y cuando quedan menos de dos. Esecialmente nada cambia con excepción de dos selecciones de tiro: triples y lanzamiendos de media distancia.

Los equipos realizan más lanzamientos de larga distancia en detrimento de los menos eficientes y quizás más difíciles lanzamientos de media distancia , especialmente cuando el equipo está perdiendo por pocos puntos y cada punto aparece como muy importante, como fue ya dicho más arriba. Con el juego sobre el final, los jugadores querrán aumentar sus chances de tener una posesión productiva a través de lanzamientos de tres, por ejemplo.

Logically, to answer to your question and let begin the discussion, it all dependes on the game situation: if your team is trailing and every point appears to matter more and more three-pointers and long distance shots shall be taken...

We made for our eBA Basketball Statistics Creative Analysis an analysis of the shot frequencies when there are more than two minutes remaining and when there are less than two. Essentially nothing changes except for two shot selections: three-pointers and midrange/post shots.  

Teams take more long distance shots at the expense of less efficient and perhaps more difficult midrange shots, especially when your team is trailing and every point appears to matter more, as said above.  With the game on the end, players want to maximize their chances of having a productive possession throughout three-pointers, for example.

• Lanzamientos en los últimos minutos del partido
• Shot selection in the last minutes of the game


( for English Translation: See Below )

Últimos minutos del partido, tiempo de tiros libres, pero además... tiene el Sistema eBA de Análisis Creativo de las Estadísticas del Baloncesto alguna investigación sobro cómo cambia la selección de los lanzamientos y el porcentaje en los últimos minutos del partido ?



Last minutes of the game, time of free throws, but also... has the eBA Basketball Statistics Creative Analysis System any research about how do shot selection & percentages become different in the last minutes of the game ?

• Posesiones y la Fortaleza de un Equipo  
• Possessions &  the Strength of a Team


( for English Translation: See Below )

La fortaleza de un equipo no está establecida ultimativamente por cuántas oportunidades de conversión el equipo obtiene ( lo que nuestro Sistema eBA de Análisis de las Estadísticas del Baloncesto llama "jugadas" ), sino por el contrario en cuánto mejor es el equipo en convertir con las posesiones que obtiene.

No existe el "bonus" porque las posesiones son aproximadamente iguales entre un equipo y su oponente en un partido dado. La forma en que nosotros definimos las posesiones (vea aquí este excelente hilo en este foro: Posesiones en Baloncesto: Sobre el Concepto, es el tiempo desde cuando un equipo obtiene el balón hasta cuando el otro equipo lo obtiene de vuelta.

Las posesiones tienen propiedades inherentes que las hacen increíblemente útiles, la más importante es que el número de posesiones entre un equipo y el otro sea equivalente.

The strength of a team is not established as the end result of a process by how many more opportunities at scoring it gets ( what our eBA Basketball Statistics Creative Analysis call "plays" ), but on the contrary how much better it is at scoring with the possessions it has.

There's no "bonus" because possessions are imprecise but fairly close to be equal between a team and its opponent in any determined game. The way we define possessions (see here this excellent thread in this forum: Basketball Possessions: About the Concept, is the time from when one team gets the ball to when the other team gets it back.

Possessions have built-in attributes that make them unmeasurable utilitarians, the largest amount of which being that the number of possessions between a team and their opponents are identical.

• Team Efficiency & Possessions Bonus
• Eficiencia de Equipo y Posesiones Bonus


( para Traducción al Español= Ver a Continuación )

This is my first question in this forum, so please forgive me if this topic is very simple or has been discussed before...

Playing with winning %, point differential, offensive and defensive efficiency, I have a problem with the possession differential: teams with more possessions than their opponents get a "bonus" to their efficiency ratings thanks to the extra possessions.
 
Therefore, I want to know what is the standard way of statistically evaluating team strength ?



Esta es mi primer pregunta en este foro, por ello por favor disculpen si la temática es muy simple o ha sido discutida ya con anterioridad...

Jugando con el porcentaje de victorias, diferencial de puntos, y las eficiencias defensivas y ofensivas, yo tengo un problema con el diferencial de las posesiones: los equipos con más posesiones que sus oponentes obtienen una "bonificación" en sus evaluaciones de eficiencia gracias a las posesiones extras.

Entonces, quisiera saber cual es la manera estándar de evaluar estadísticamente la fuerza del equipo ?
