William Anthony Parker Jr. is a French-American former professional basketball player and majority owner of ASVEL Basket in the LNB Pro A. Himself the son of a basketball pro, Parker started his career at Paris Basket Racing in the French basketball league before joining the San Antonio Spurs of the National Basketball Association (NBA). He was selected by the Spurs with the 28th overall pick in the 2001 NBA draft, and quickly became their starting point guard. Parker won four NBA championships, all of which were with the Spurs. He also played for ASVEL Basket in France during the 2011 NBA lockout, and finished his playing career after one season with the Charlotte Hornets. He retired as the ninth leading scorer and fifth leading passer in NBA playoffs history.

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.
