Timothy Theodore Duncan is an American former professional basketball player. He spent his entire 19-year career with the San Antonio Spurs in the National Basketball Association (NBA). Nicknamed "the Big Fundamental", he is widely regarded as the greatest power forward of all time and one of the greatest players in NBA history, and was a central contributor to the franchise's success during the 2000s and 2010s. He was inducted into the Naismith Memorial Basketball Hall of Fame in 2020 and named to the NBA 75th Anniversary Team in 2021.

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.
