When I played basketball we had two guards, two forwards and a center. Now the terminology is beyond me. What is a small forward and what is the two-spot, the three-spot? For that matter, the four-spot and five-spot?
One is the point guard, the primary ball-handler.
Two is the shooting guard, usually a team's second-best ball-handler and best outside shooter.
Three is the shooting forward whose primary job is to make 8- to 10-foot shots and to rebound.
Four is the power forward whose main job is to rebound and shoot from the 3- to 8-foot range.
Five is the center whose job is to rebound, take shots close to the basket and block opponents' shots.
