Generating defensive plays in basketball games
Analyzing players’ performance and behaviors based on statistical and historical data is becoming an effective way for coaches in National Basketball Association (NBA) to develop winning strategies. For example, the analysis can help determine the line-up as well as match-ups in a game and choose the offensive and defensive strategies against the opposing team. It also can help players identify their weaknesses so as to polish their skills. Among the teams in NBA, the Houston Rockets are most well known for using statistical analysis, which has become known as the Moreyball.
Recently, more teams, such as the Toronto Raptors, adopted similar methodologies, with their analytics team even creating a system to teach players what they should have done on a play. Prior research in basketball games is mainly based on analyzing broadcast videos, in addressing challenging problems such as player tracking, perspective effect, dynamic camera motion, and occlusions. Engineers in STATS LLC cooperated with NBA teams and adopted an alternative way to prevent the occurrence of the above mentioned problems when analyzing sport videos. They installed static video cameras at the top of the stadium to track positions of the players and the ball. Some of these data have been released, making sports data analytics a promising research area.
