The NBA Draft Combine is a multi-day showcase that takes place every May before the annual June NBA draft. At the combine, college basketball players are measured and take medical tests, are interviewed, perform various athletic tests and shooting drills, and play in five-on-five drills for an audience of National Basketball Association (NBA) coaches, general managers, and scouts. Athletes attend by invitation only. An athlete's performance during the combine can affect perception, draft status, salary, and ultimately the player's career.
