In basketball, there are five players on court per team, each assigned to positions. Historically, these players have been assigned to positions defined by the role they play on the court, from a strategic point of view. The three main positions are guard, forward, and center, with the standard team featuring two guards, two forwards, and a center. Over time, as more specialized roles developed, each of the guards and forwards came to be differentiated, and today each of the five positions is known by a unique name and number: point guard (PG) or 1, the shooting guard (SG) or 2, the small forward (SF) or 3, the power forward (PF) or 4, and the center (C) or 5 "post position".
