What is the consequence if a player fails to allow the opponent one normal step while screening?

When a player sets a screen, they must give their opponent a fair chance to maneuver past it. If the screener does not allow the opponent one normal step, it constitutes an illegal screen. The rules are designed to ensure that players can move freely on the court and that screens are set legally without impeding opponents unfairly.

In this scenario, the screener's failure to provide that space leads to a foul being called against them. This decision is enforced to maintain fair play and prevent obstruction that could lead to unsafe conditions on the court. A foul on the screener can result in the opposing team gaining possession of the basketball, ensuring that justice is served in the flow of the game. The emphasis on allowing one normal step is crucial for players' safety and the game's integrity.

This understanding supports the rationale behind enforcing rules on screening, setting a standard for how players interact on the court.
