I had a regional semi-final the other day. Went to OT. Ended up a 2-point game, 51 - 49.
I had a very contentious bang-bang block-charge play. The B player was definitely not moving forward. Team A coach was very adamant that I had the wrong call. He's voicing for a block: "he was moving - you can't move laterally".
During a TO soon afterwards, I'm right in front of this coach, so I address him. I explain the two-step process: first LGP, then the legal moves that B may perform after LGP, and finally the move that B cannot do legally. This coach realizes he is rooked, and says, "I question whether he had legal guarding position".
