three-second rule
Quick Summary
The "three-second rule" in basketball is a rule designed to prevent offensive players from lingering in the key (the area under the basket) for too long. Specifically, an attacking player cannot remain in the foul lane for more than three seconds. This rule was instituted to prevent tall players from gaining an unfair advantage by simply standing near the basket and to encourage a more dynamic offensive game.1
The rule was first implemented in the 1930s, evolving from earlier attempts to speed up the game and discourage stalling tactics. It applies to any attacking player in the foul lane, ensuring that teams move the ball and create scoring opportunities rather than relying on stationary players.1
