Set plays are planned movements or strategies used in sports, particularly in games like soccer and basketball. They are designed to create scoring opportunities or to defend against the opposing team. Coaches develop these plays during practice, allowing players to understand their roles and positions when the play is executed. In soccer, set plays often occur during free kicks, corner kicks, or throw-ins, where players follow specific patterns to confuse defenders. In basketball, set plays can be used during inbounds situations or after timeouts, helping teams to organize their offense and maximize their chances of scoring.
