Towards an objective team efficiency rate in basketball
[Vers une évaluation objective de la performance d’une équipe en basketball]
Journal de la société française de statistique, Numéro spécial : Sport et Statistique, Tome 156 (2015) no. 2, pp. 51-68.

Tirant profit des nombreuses statistiques issues des matchs de basketball, nous proposons un score d’évaluation de la performance d’une équipe qui retranscrit bien son classement final. Ce score d’évaluation objective est différent des scores classiques d’évaluation des joueurs. Les qualités de notre score sont illustrées pour le championnat français de PRO A et le championnat américain de NBA. De plus, son application pour les joueurs nous a conduit à proposer un score spécifique pour une meilleure prise en compte des performances individuelles.

Taking profit of the numerous statistics on basketball games, we propose a team efficiency rate well related with the ranking of the teams after the regular season. This “objective” efficiency rate is different from the standard efficiency rate used to assess the player performances. The ability of this objective team efficiency rate to recover the season ranking is illustrated for the French PRO A championship and for the NBA championship. Moreover, analyzing the scores we get for the players with this “objective” efficiency rate lead us to propose a specific objective player efficiency rate to better take into account their performances.
