Julius Winfield Erving II, commonly known by the nickname Dr. J, is an American former professional basketball player. Erving helped legitimize the American Basketball Association (ABA), and he was the best-known player in that league when it merged into the National Basketball Association (NBA) after the 1975–1976 season.

Basketball is a team sport in which two teams, most commonly of five players each, opposing one another on a rectangular court, compete with the primary objective of shooting a basketball through the defender's hoop, while preventing the opposing team from shooting through their own hoop. A field goal is worth two points, unless made from behind the three-point line, when it is worth three. After a foul, timed play stops and the player fouled or designated to shoot a technical foul is given one, two or three one-point free throws. The team with the most points at the end of the game wins, but if regulation play expires with the score tied, an additional period of play (overtime) is mandated.
