Guard (basketball)

The five basketball positions normally employed by organized basketball teams are the point guard (PG), the shooting guard (SG), the small forward (SF), the power forward (PF), and the center (C). While these position names are still used, most modern teams use a point guard, two wings, and two post players, or use no specific positions at all. The rules of basketball do not mandate them, and they are sometimes not used. Indeed, it could be said that the designation of positions is done more to satisfy broadcasters and fans than for coaches or players, and many top coaches, including Olympic coach Mike Krzyzewski choose to ignore positions altogether.

Typically, the point guard is the leader of the team when on the court. This position requires substantial ball handling skills and the ability to facilitate the team during a play. The shooting guard, as the name implies, is often the best shooter. They are probably capable of shooting accurately from longer distances. Generally, they also have good ball-handling skills. The small forward often has an aggressive approach to the basket when handling the ball. The power forward is considered to be what is called a post player or a big. A post player typically works around the basket, often with lay-ups or shots near the basket. The center is also considered a big. They work primarily around the basket, mostly shooting layups, and don't dribble the ball as often.

The point guard (PG), also known as the one, is typically the team's best ball handler and passer. Therefore, they often lead their team in assists and steals. They are often quick and are able to hit shots either outside the three-point line or "in the paint", largely depending on the player's skill level. Point guards are looked upon as the "floor general" or the "coach on the floor". They should study the game and game film to be able to recognize the weaknesses of the defense, and the strengths of their own offense. They are responsible for directing plays, making the position equivalent to that of attacking midfielder in Association football, quarterback in American football, center in ice hockey, or setter in volleyball. Good point guards increase team efficiency and generally have a high number of assists. They are often referred to as dribblers or play-makers. In the NBA, point guards are usually the shortest players on the team and are mostly 6 feet 5 inches (1.96 m) or shorter.
