A ball screen is a broad term for any basketball screen set for the player who is currently in possession of the basketball.
Having players who set strong, legal screens is crucial for any basketball team. Basketball screens are a great way to get players open to receive the basketball and give your team an advantage on offense. But let's not get ahead of ourselves.

"What is a basketball screen?"
A basketball screen is a way to block a defensive player.
When a screen is set, the screener's teammate will have a better chance of getting open because their defender will have to avoid the screen before getting back into defensive position. This is a huge advantage to the offensive team.
