Is there moving screen in the paint?

[Camron Rust]

Come on guys! It's not that hard to figure out what he's asking.

If B1 (the defender) is trying to get by A2 (you) to the shooter (A1), you have to set a legal screen to not commit a foul. If you (A2) are moving when there is contact, you've likely committed a foul (unless you're moving directly away from B1).

Also considered is whether team A gains an advantage from the contact. If B1 was close enough to get to the shooter before the shot if not for A2's illegal screen, that is an advantage. If they're too far away, no advantage...no call...since B1 would have been there too late to make a play on the shot.

The official has to distinguish B1 and A2 are merely jockying (legally) for a better position in the post or if B2 is trying to get to A1. If A2 is moving and there is contact but B1 is not trying to get to A1 (official's judgement) there will likely be no foul...it's not a screen.
