Recognizing the difference between a block and a change isn't the easiest thing to do when in the height of a NBA game. For that reason, the NBA's competition committee gathered in San Antonio to discuss rules changes to instant replay -- a change which would allow referees to review block/charge calls in end-of-game situations. It marks the first time the league is thinking of using replay to assess judgment calls by refs. What do you make of the possible rule change?
