Oscar Palmer Robertson, nicknamed "the Big O", is an American former professional basketball player who played for the Cincinnati Royals and Milwaukee Bucks in the National Basketball Association (NBA). Robertson played point guard and was a 12-time All-Star, 11-time member of the All-NBA Team, and one-time winner of the MVP award in 14 seasons. In 1962, he became the first player in NBA history to average a triple-double for a season. In the 1970–71 NBA season, he was a key player on the team that brought the Bucks their first NBA title. His playing career, especially during high school and college, was plagued by racism.

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.
