Interview Brian McCormick: Coach de Basket, Chercheur et Ecrivain

Je vous propose l'interview de Brian McCormick (BMC), un entraîneur de basket-ball américain qui a travaillé aux USA et en Europe.



Brian vient de finir son doctorat qui portait sur l'agilité, la pliométrie et le basket-ball. Il a publié 3 articles scientifiques dans des revues internationales.

Il a également écrit plusieurs livres sur le basket-ball disponible sur amazon.fr:

  • Cross-over: the new model of youth basketball development
  • Developing basketball intelligence
  • Fake Fundamentals vol. 1 et 2
  • SABA: The antifragile offense
  • The 21st century basketball practice
  • 180 shooter
Enfin, il possède un blog sur lequel il rédige régulièrement des petits articles:

Brian est intéressé pour venir entraîner en France afin de découvrir un nouveau pays. Si des personnes souhaitent lui donner sa chance, vous pouvez me contacter et je ferai suivre.


SF: Hello Brian, 
I'm very pleased to have the opportunity to introduce you to our French readers.
First of all, can you introduce yourself and tell us a little bit about your background?

BMC: I started out coaching youth teams when I was at university. I started with 5th and 6th grade girls in a league for parochial schools. I coached volleyball and basketball, and on the weekends, I coached Special Olympics. Eventually I moved on to AAU teams and high school teams, and when I graduated from university, I was hired as an assistant coach at an NCAA D3 program. I was a college assistant for two seasons, also coaching AAU basketball during the offseason, before I was hired to coach in the Damligan in Sweden. 
     When I left Sweden, I started a business doing individual and small-group training with players, partnered with another guy to start an online training business, and wrote a documentary for a Canadian film company. I also wrote the first of my books, Cross Over: The New Model of Youth Basketball Development, and produced my DVD, Great Ball Handling Made Easy during this time. Eventually I found my way back to Europe and coached UCD Marian in Ireland. When I returned to the U.S., I spent several years coaching high school teams, wrote several more books, started the 180 Shooter online shooting program, founded a coach education and certification organization, and created the Playmakers Basketball Development League. 
     After several years, I returned to school to complete a doctorate in Exercise and Sports Science. I wrote my dissertation on plyometrics training and basketball defense. While in school, I worked as a strength and conditioning coach at a junior college and continued to coach high-school basketball. After graduating, I returned to Europe to coach in Denmark. This year, I assisted with a college basketball team while writing four more books.

SF: You travelled a lot and coached in different countries. What do you think about young player development in the USA compared to Europe?

BMC: In some ways, this is a difficult question because every country in Europe, and even every club, is different, and there is a lot of variation in the experiences of players in the U.S. too. Also, despite coaching in a number of countries, with teams and while directing camps, I have not watched many European coaches over a long period of time.

From my experiences, I believe that the club system in Europe presents several advantages:

(1)    Children play on one team, and the head coach oversees all aspects of the program. In the U.S., children play for multiple teams (high school, AAU, etc) and also work out with private skills trainers and strength coaches. There is a lack of consistency in their development, as they bounce from coach to coach, system to system.

(2)    The European club system has more of a long-term emphasis. Children tend to stay with the same club for several years, whereas children may be with a team for as few as 8 weeks in the U.S. before moving to another team with another coach. Again, there is more consistency.

(3)    Also, the season tends to be longer and games tend to be on the weekends, with practices during the week. In the U.S., for children, this is the same, but weekends are filled with multiple games; a child may practice 1-2 times per week during the week, and play 3-4 games on the weekend in a tournament. In high school, most games are during the week, so a player might practice Monday, play Tuesday, practice Wednesday & Thursday, and play Friday. It changes the structure and emphasis of practice when every practice is either the day before or the day after a game compared to a schedule in Europe with 3-4 practices during the week before a game on Saturday. With fewer games per week, and more practices in between games, there is more time for general skill development, whereas the U.S. system forces coaches to spend a large percentage of time on game preparation.

(4)    I believe the FIBA rules, especially with regards to timeouts and the shot clock, benefit player development as well. Players learn to play faster and they cannot set up again when the first play did not go according to plan. Players have to control the game more, whereas coaches are more heavily involved in game management under U.S. rules. Most European clubs seem to play with more age-appropriate basket heights and ball sizes than are used with young children in the U.S., where players quickly move to full-size balls and 10-ft hoops.

(5)    I do believe the U.S. system has some advantage. Many children play multiple sports, which is rarer for teenagers in Europe, and that benefits them athletically. Second, players are exposed to many systems and coaches, which has some benefits, as they learn different styles of play, different positions, and more. I also think the school system allows or encourages more children to participate.



SF: What do you thing of the playing level in High School or in the NCAA?

BMC: It varies significantly. There are so many players, so many teams, and so many levels that it is hard to characterize as one thing. There is a perception that young players in other countries are better or more fundamental, as Kobe Bryant suggested. However, the comparison is generally between the absolute best players from the rest of the world and players who might be the 100th or 200th best player in his or her age group. There are certainly top players being developed everywhere in the world, but people underestimate the depth of the U.S. For instance, when I coached in Denmark, there were 12 teams with 12 players on each team in the highest league. 144 players. There are over 300 teams with 12 players on each team just in NCAA D1 basketball. Thats a huge difference when youre comparing the top 12-20 teams in a European league with a 300+ team NCAA. If the top 20 college teams broke away from the NCAA and formed its own super-college league, I imagine there would be improvements in style of play, execution, etc.
The same goes for high school. Some high school games are great; some are awful. Some feature great players; some do not. There are so many teams and players that you cannot draw a single conclusion.

SF: According to you, what are the priorities for the development of young players?

BMC: My first priority is the psychological or emotional. Players have to want to play. They have to want to improve. It cannot be for their parents. They have to understand the process of development, that it takes time. They cannot fear a mistake today. Too many players are pushed into training at too young of an age (biological age and/or emotional age), and they are not ready for it mentally or physically. These players should be playing sports, not training for sports. They should be playing for fun.
Once they are emotionally and psychologically ready to move to a more developmental period, my initial focus is movement. Basketball is a movement sport; players have to be able to run and stop, jump and land, and change directions. These skills impact basketball-specific skills such as shooting and dribbling. How can you shoot well if you cannot jump and land or run and stop?
These are my priorities. After these, then I like to use games to develop basketball-specific skills and game sense. I want to build skills within the game rather than developing isolated skills and trying to perform them in the games later.

SF: What is your playing philosophy for youth teams? Do you use closed systems or principles based on the “read and react”?

BMC: I use the system that I describe in SABA: The Antifragile Offense, which is an outgrowth of the former system that I used that I described in Blitz Basketball. Basically, I teach several basic principles and build the system around these principles. There are some plays or entries that we use to organize our offense, but the goal is not to run the plays, but to break down the defense. We want to disorganize the defense, and once disorganized, we move the ball until we take a great shot. The offense is predicated on players making decisions and making plays rather than following directions.

SF: When do you think it is a good age to start learning pick & roll and off-ball screens?

BMC: I start with pick-and-rolls at a young age because it is easier for players to understand the pick-and-roll than off-ball screens. I introduce it with players as young as 10. With off-ball screens, I wait another year or two. I want players to be able to get open and find space without having to rely on screens.

SF: How many sessions per week youth teams (U14 for example) train in the USA? Usually, what is the week training schedule?

BMC: This is hard to answer because it varies greatly. An u14 is probably in 8th grade, but could be in high school. There is a big difference between a middle school team and a high school team. Additionally, most players also play on a club (AAU) team, which complicates their training schedule.
In general, a typical schedule for a freshman in high school during the high school season is to play 2 games and practice 3 times per week. The season starts in mid-November and ends in mid-February. The school system is based around a three-sport season, so basketball starts when football (boys) and volleyball (girls) end, and ends in time for track and field, baseball/softball, swimming, and other sports.
After the high school season, many players will play with a club team. This starts as soon as the high school season ends, and it may be a school-affiliated club team or a non-affiliated team, depending on the state. Some states allow high school coaches to coach their players in the offseason, and some states restrict the offseason involvement.
The club season generally will include 1-3 practices per week and 3-4 games on the weekend. This goes from mid-February to the end of July with very few breaks.
Some players will play multiple sports at school (football, basketball, baseball), play on a club basketball team, and train with a private skills coach. They have a crazy schedule, running from practice to practice to games to workouts.


SF: During youth training, do you mainly use individual technical drills, small sided games (1-on-1, 2-on-2, 3-on-3), or 5-on-5 games?

BMC: I use primarily small-sided games. As the season progresses, I use more 5-on-5 games to prepare for specific offenses and defenses of our opponents. However, I do most of my teaching and skill development through SSGs.

SF: What is the best way for you to teach basketball shooting to young players?

BMC: I focus on the basic movements. When I start with a player, I want the player to start in a good position and end in a good position. There is some leeway in terms of what constitutes a good position, and I do not want to influence this too much, unless there is something completely amiss, such as a right-handed shooter shooting on the left-hand side of their body, as some children do.
More and more, I believe that shooting needs to be developed within the same constraints as the game, which means fewer isolated shooting drills, and more time spent shooting with some decision-making elements, such as shot selection or judging the closeness of a defender.

SF: What are the necessary physical qualities to become a professional player?

BMC: Length and quickness. Basketball is a game of movement. A game features more changes of direction than vertical jumps, so while we think of basketball as a game of jumping played at the rim, the ability to move and change directions quickly is more important. Length is also hugely important in terms of becoming a professional player. Most people still concentrate on height, but a shorter player with a longer standing reach often has the advantage. Players with that long wingspan have an advantage, especially on defense, as you can see with guys such as Draymond Green and Russell Westbrook.
The underrated physical quality is coordination or connectedness. Some athletes are powerful, but they are not well-connected. Their movements are not as fluid. They may test well, especially in static tests, but their skills are not expressed as fully as a less powerful athlete who is more coordinated. This is a big concern with regards to shooting. Players may appear to have very good technique, but their coordination is slightly off. They are not connected. This is a quality that is easy to see in top athletes, but harder to explain because of its complexity and interconnectedness with other qualities, especially balance.

SF: Do you think it is important to start playing basketball at a young age to become a professional player? What is the ideal age?

BMC: I suppose it depends on what age one considers to be young. I believe that it is important for a child to be active from a young age, but I do not believe that one needs to play basketball before 10 or 11. From 4-10, however, the child must be engaged in playful activities. I recommend gymnastics and martial arts to young children because of the kinesthetic awareness, strength, and coordination benefits. I also believe that it is good for children to engage in sports such as skiing, snowboarding, surfing, and skateboarding. Playing team sports or something with a ball is also important; I notice a difference in the U.S. between children who have played baseball and those who have not. Those with baseball experience are better at tracking balls and anticipating where the ball will go than those with no baseball experience. I imagine the same would be true whether they played volleyball, tennis, baseball, etc. Anything that develops the eye tracking skills is beneficial and probably important. With a background in these activities, whether formal or informal, I believe that a child can transition to basketball quite easily around 10 or 11 years old.


Thanks a lot for your answers Brian.

Comment tirer aussi vite que Stephen Curry?

Stephen Curry est le joueur possédant un des tirs les plus rapides de la NBA. Cela lui permet de réussir des tirs dans des conditions très difficiles, par exemple lorsque le défenseur est très proche de lui.
Evidemment, sa gestuelle de tir et son adresse se sont améliorées grâce à de nombreuses heures d'entraînement.



Stephen Curry possède un "One motion shot", c'est-à-dire un "tir en 1 mouvement", qu'on appelle également "tir en extension" en opposition au "tir en suspension" ou "Two motion shot"


Plusieurs caractéristiques permettent d'expliquer la rapidité de son geste de tir:
  • Un regard porté vers le cercle bien avant de commencer son tir. Cela permet de viser très tôt et donc de rapidement programmer le geste de tir en fonction de la position du panier par rapport au joueur
  • Une pose d'appui rapide et avec le bon timing
  • Une coordination inter-segmentaire parfaite
  • Une grande vitesse d'exécution gestuelle 

Ces caractéristiques assurent un geste de tir rapide et fluide qui donne l'impression que le joueur ne force pas pour tirer même lorsqu'il est à longue distance.

On va principalement s'intéresser dans cet article à la coordination inter-segmentaire, et notamment à la coordination entre les membres supérieurs et les membres inférieurs. Cette coordination inter-segmentaire est évidemment régulée par la coordination inter-musculaire.
La bonne coordination est celle qui permet d'utiliser au maximum la vitesse des membres inférieurs dans la gestuelle de tir.

On se place ici dans le cas d'un tir en extension et en appui alternatif (pose du pied gauche puis du pied droit).



Voici les différentes phases du tir de Stephen Curry:
  1. Regard vers le cercle. Pose du pied gauche et descente du ballon au niveau du bassin ("Dip").
  2. Avant de poser son pied droit au sol, il commence à monter le ballon par une antépulsion des épaules. 
  3. Au moment où il pose le pied droit, le ballon est à hauteur de la poitrine ou des épaules. Légère flexion des membres inférieurs (cheville, genou, hanche).
  4. Quand il commence l'extension des membres inférieurs, le ballon est au niveau de sa tête.
  5. Les pieds sont toujours au sol, le ballon est en position haute. L'extension des membres inférieurs est presque complète. L'antépulsion de l'épaule se poursuit et l'extension du coude va commencer. 
  6. Les pieds ont quitté le sol, l'extension du coude a commencé. Le corps est bien équilibré.
  7. L'extension du coude est complète et le poignet est fléchi (fouetté). Le bras gauche est également tendu. 
Il faut ajouter à tout cela une grande vitesse gestuelle de Stephen Curry.
Cependant, il faut toujours se rappeler que la vitesse d'exécution ne doit pas se faire au détriment de la qualité gestuelle du tir.

De plus, il est possible d'améliorer la vitesse du tir en utilisant l'appui simultanée ("Hop"). On reviendra sur ce type d'appui dans un prochain article.




On peut remarquer, en observant le tir de Juan-Carlos Navarro, que celui-ci possède à peu près la même coordination inter-segmentaire que Stephen Curry.
JC Navarro possède également un tir en extension et on connaît sa capacité à tirer très vite. 





Cette coordination inter-segmentaire n'est évidemment pas la seule possible et d'autres joueurs très adroits peuvent avoir une coordination différente.

Par ailleurs, la coordination sera différente entre le tir en extension ("One motion shot") et le tir en suspension ("Two motion shot").

Pour améliorer votre vitesse de tir, vous pouvez donc vous inspirer du geste de Stephen Curry.

Faut-il armer le poignet en position basse lors du tir au basket-ball?

En introduction, je vais juste préciser à nouveau la différence entre la position basse et la position haute du tir par les photos suivantes.
          Position basse du tir                  Position haute du tir


Avoir un tir fluide et relâché nécessite une très bonne coordination inter-musculaire avec un minimum de contractions musculaires parasites. Il faut le plus souvent chercher à supprimer ou à modifier certaines activations musculaires (intensité, timing,...) qui nuisent généralement à la fluidité du tir.

Tous les entraîneurs savent que l'articulation du poignet effectue un mouvement d'extension (armé) puis de flexion (fouetté) lors du geste de tir au basket-ball. Cependant, le timing de ces mouvements lors du geste de tir est souvent mal compris.

Par exemple, on peut remarquer chez certains jeunes joueurs un armé précoce du poignet dans la position basse du tir.
Dans ce cas, le joueur contracte alors les extenseurs du poignet en position basse. Cette contraction précoce peut entraîner chez certains joueurs un écartement du coude par rapport à l'axe du corps. De plus, elle perturbe le plus souvent la fluidité du mouvement du poignet lors du tir. En effet, cette action d'extension du poignet doit se faire de manière progressive et continue lors du tir, et non de manière anticipée au début du geste.   
   
En observant les meilleurs shooteurs au monde, on remarque que ces derniers n'arment pas leur poignet dans la position basse. Le poignet est en position neutre, ou en très légère extension. Voici quelques photos qui prouvent cette affirmation.


Kevin Durant (NBA)

 Stephen Curry (NBA)

Kyle Korver (NBA)

Steve Nash (NBA)

JJ Redick (NBA)

Ray Allen (NBA)


Finalement, l'armé du poignet se fait de manière continue et progressive avant d'arriver en position haute pour pouvoir effectuer le fouetté (mouvement de flexion) du poignet lors de l'extension du bras. 


Stephen Curry (NBA)

Ray Allen (NBA)

Voici une vidéo slow motion du tir de Xavier Corosine (Paris-Levallois) dans laquelle vous observerez le poignet neutre en position basse et le timing de l'extension du poignet lors de l'armé du geste. On peut observer également la main droite qui commence sur le côté du ballon et qui vient se positionner progressivement sous le ballon, à l'instar de Stephen Curry ou de Ray Allen.



J'attends vos commentaires.

Faut-il avoir un creux de la main sous le ballon lors du tir au basket-ball?

Depuis toujours, les entraîneurs de basket-ball ont demandé à leurs joueurs de former un creux sous le ballon pour la main qui tire (main droite pour les droitiers et main gauche pour les gauchers).
Il me semble qu'il faut désormais évoluer sur cette consigne donnée aux joueurs pour améliorer leur adresse et se rapprocher de ce que font les meilleurs shooteurs au monde. 

En effet, quand on observe les meilleurs tireurs NBA, Euroleague et de la Pro A, on remarque que ces joueurs n'ont pas de creux sous le ballon. Au contraire, on peut même se rendre compte que la main est plate. 

Je vous montre des photos de ces joueurs afin de mieux vous convaincre.

Stephen curry (NBA)







 Kyle Korver (NBA)

Klay Thompson (NBA)

Kobe Bryant (NBA)


 Kyrie Irving (NBA)


Kevin Durant (NBA)


Carmelo Anthony (NBA)


 Steve Nash (NBA)



 Jaycee Carroll (Real Madrid, Euroleague)



Jamar Smith (Limoges, Pro A)

 Hugo Invernizzi (Le Havre, Pro A)


Former un creux sous la balle dès le début du tir demande une ouverture du pouce plus importante, ce qui nuit au relâchement du poignet et donc entraîne une perte de fluidité dans le tir.
Attention toutefois à ne pas avoir un pouce trop fermé qui peut nuire au bon contrôle du ballon.

Finalement, il y a bien un creux qui apparaît au moment du tir, mais ce creux se produit lors de l'extension du bras quand le ballon commence à quitter la main.





Observez dès votre prochain entraînement les meilleurs shooteurs de votre club ou de votre équipe et vous verrez sans doute qu'ils n'ont pas de creux sous le ballon.

A vous de choisir maintenant!
