Rule 10, Section 22, Article 4:
No player, while moving, shall set a screen that causes contact or delays an opponent from reaching a desired position.
I suppose if A1 gets around B1's screen, and B1 moves with A1 in an effort to keep the screen, it would be a blocking foul (assuming B1 doesn't use his hands)? I missed the ref's signal to the scorer's table.
Makes sense to me.
Thanks Dan.
