IMHO, the red player was trying to avoid falling on the white player who managed to end up under him.. He managed to avoid hurting himself and the other player. That makes him a conscientious and caring lad who respects the game and his opponents. That's an easy sell if the anybody starts griping about grasping the rim.
The HC should be aware of where he is on the floor, but whacking him for stepping 10 inches outside his box is asking for trouble. I believe game management should take precedence over letter-of-the-law. If IAABO expects us to call each and every play by the book, freshmen girls' games would take three hours.
