If the screener stops while screening a moving opponent, what is likely to occur?

When the screener stops while attempting to screen a moving opponent, the most likely outcome is that the opponent may collide with the screener. This scenario can lead to unintended contact, which is often viewed as the result of the screener's actions and movement. The purpose of a screen is to create a barrier or provide an obstruction to the defender's path, allowing the offensive player to gain an advantage.

In basketball, when a screen is properly executed, the screener maintains a stationary position to avoid fouling due to illegal picks. However, if the screener abruptly stops while the opponent is in motion, it creates an increased risk for contact, resulting in a collision. This potential for collision is what often leads to fouls being called, particularly if the screener has not established a legal screening position before stopping.
