In this study a well-known tool for relative efficiency assessment, namely Data Envelopment Analysis (DEA) especially for non-profit organizations, was used to measure the performance of the basketball players at season 2004 Super Basketball League (SBL). The proposed approach considered one inputs (time) and six outputs (scores, rebounds, assists, blocks, steals, turnovers) to measure the efficiency of 28 qualified basketball players (DMU) of SBL. The results were analyzed and the performance indexes as well as benchmarks were computed for each basketball player. In addition, plotting the performance of a specific ball player for games could help identify trends and enhance coaching as well as objective successes to create teams' greatest victory.
