The vector stencils library "Basketball positions" contains 12 symbols for drawing basketball positions diagrams.
"The three basketball positions normally employed by organized basketball teams are the guards, forwards, and the center. More specifically, they can be classified into the five positions: point guard (PG), shooting guard (SG), small forward (SF), power forward (PF), and center (C). The rules of basketball do not mandate them, and in informal games they are sometimes not used." [Basketball positions. Wikipedia]
The symbols example "Design elements - Basketball positions" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Basketball solution from the Sport area of ConceptDraw Solution Park.
