Had an interesting sitation last night.
A1 goes up for a fast break layup and B1 is setup slightly to his right to try to take a charge. A1 at first holds left going up for the layup to avoid the contact. B2 comes in and has a clean block (but the kind that if it was held for another second could've been a jump ball). The change in momentum sends A1 crashing into B1, who had maintained his legal guarding position (or rather his "Ready to take a charge" position haha).
I had a no call but wondered what you all thought?
