Sure, go ahead and interject something more controversial to slow the game down. (reviewing PI calls). Look, good refs aren't always perfect, but how come we often see things happen right in front of refs that appear to be blatantly missed. Replay doesn't fix everything either, take the dodgers game last night for example, call at home was out and for that home plate ump, it was not a missed call, but I firmly believe replay showed him to be safe but MLB did not over turn it for whatever reason.
