Screen (sports)

A screen, in various sports, is a blocking maneuver used to impede the movement of an opponent, thereby creating an advantage for a teammate. The legality and specific execution of a screen vary significantly across different sports. The primary goal is to position oneself between an opponent and the player the screener is trying to help, allowing the latter to move freely or gain an advantageous position.

Basketball: In basketball, a screen (also known as a pick) is a legal blocking move by an offensive player. The screener positions themselves near a defender, allowing a teammate to move past them and potentially receive a pass or drive to the basket. To be legal, the screener must establish a stable position, giving the defender adequate time and space to avoid contact. Illegal screens, where the screener is moving or fails to provide sufficient space, result in an offensive foul.

American Football: In American football, a screen pass is a type of offensive play where the quarterback quickly throws a short pass to a running back or wide receiver who is positioned behind a line of blockers. These blockers "screen" the defensive players, preventing them from tackling the receiver or running back before they can advance downfield. The success of a screen pass depends on the ability of the blockers to effectively impede the defensive players.

Ice Hockey: In ice hockey, a screen occurs when a player positions themselves in front of the opposing goalie, obstructing the goalie's view of the puck. This is a legal tactic, provided the player does not interfere with the goalie's ability to move or make saves. The player providing the screen aims to obscure the goalie's vision, increasing the likelihood of a goal being scored.

Lacrosse: Similar to basketball, lacrosse uses screens to create open shots or driving lanes. Offensive players will set screens on defenders to free up teammates for scoring opportunities. Rules regarding legal screening are enforced to prevent excessively physical or dangerous play.

The effectiveness of a screen depends on factors such as timing, positioning, and the awareness of both the screener and the player being screened for. Strategic use of screens is a fundamental aspect of many team sports, contributing to offensive flow and scoring opportunities.
