This would be called something to the effect of a kill/ hit catch. This would be mostly on the rush due to close quarters. If player A throws a ball and hits player B he would be out. If the ball thrown is in the air player A could catch that ball before it becomes dead to count as a catch for his team. This would give teams more incentive to throw on the rush and get teammates back in that got caught or thrown out right away. It would also encourage teams to throw at a target (a real person) more than just throwing a step and lunge away throw to restart their shot clock. Again I just feel like it’s another aspect of the game that would not drastically change it, but would add another element to game strategy.
