BlitzkriegBob you are correct in not using advantage/disadvantage to your thought process. We are there to enforce the rules as written and to the best of our ability. If we started questioning our thought process then we would not be objective. How many times have you seen a team being destroyed and then come back and win because of a change of events. What if that change of events was because you as an umpire decided to not make a call because you didn't want to cause an uproar. Remember every call we make is an advantage/ disadvantage depending on which dugout you are looking out of.
