George Lawrence Mikan Jr., nicknamed "Mr. Basketball", was an American professional basketball player for the Chicago American Gears of the National Basketball League (NBL) and the Minneapolis Lakers of the NBL, the Basketball Association of America (BAA) and the National Basketball Association (NBA). Invariably playing with thick, round spectacles, the 6 ft 10 in (2.08 m), 245 lb (111 kg) Mikan was one of the pioneers of professional basketball. Through his size and play, he redefined basketball as a game dominated in his day by "big men". His prolific rebounding, shot blocking, and ability to shoot over smaller defenders with his ambidextrous hook shot all helped to change the game. He also utilized the underhanded free-throw shooting technique long before Rick Barry made it his signature shot.

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.
