The Summer League is a series of basketball games held during the off-season, primarily for teams in the NBA. It provides young players, rookies, and those on the fringe of the roster an opportunity to showcase their skills and gain experience. The games are typically less formal than regular season matches, allowing for experimentation and development. These leagues are hosted in various cities, with the most notable being the NBA Summer League in Las Vegas. Coaches and scouts closely observe the games to evaluate talent and make decisions about player contracts and team rosters for the upcoming season.
