The National Basketball Associations Summer League (also called the Reebok Pro Summer League) is a pro basketball league run by the NBA. The league starts up each year following the National Basketball Associations draft. Each of the teams consist of a group of NBA players who have been in the league for three years or less. It also gives other players the opportunity to hopefully get an invitation to training camp. They also include the newly drafted players to give them a chance to practice against other players.
