illegal screen

[Pantherdreams]

How about this (not to hijack the post but . . .):

Do you call an illegal screen where contact occurs automatically? Or do you treat it like any other fouling situation and let advantage disadvantage play a key role assuming it doesn't lead to rough play??

I guess I see lots of border line screen (poor technique, poor coaching, etc) and struggle with when to call them and when not to. I don't want to let illegal screening go and have it get out of hand but if the defender gets through it anyway or they are no more disadvantaged then they would have been if the kid hadn't stepped or lifted their arms what do you do?

examples: PLayer A sets a screen and lifts elbows and raises arms so they are way outside the body and up. Defender B hits the screen but hits it in the chest and where fists meet so they elbows make no impact on the play as they immediatley switch? Call?

Player A moves in to set a screen and is moving into defender but defender overpowers screener anyway and isn't impeded. Call?
