In basketball competitions, defense and offense are constantly alternated. The positions of basketball players include point guard, shooting guard, small forward, power forward, and center, each with different functions. The Croatian research teams conducted research on the evaluation of the ability of basketball players in different game positions and proposed the evaluation criteria including 7 items on defense and 12 items on offense and assigned different levels of weight to each index. It is hoped that coaches can increase their understanding of these indicators, expand their horizons in basketball competition, train as well as talent identification. Hopefully, basketball players can use the system to motivate themselves and apply it as a self-evaluation to be a good player.
