[Rain Man]

I think you politely point out the error on close calls against your team, and you politely acknowledge all calls against the other team. If you argue against all calls against your team, then you lose credibility, and if you acknowledge only close calls against the other team, then you're acknowledging that they were close, which may have some competitive disadvantage on a makeup call or something.

I would also politely argue my case on replays, but only if I felt that I had a good argument. Again, you don't want to lose credibility by advocating something that's obviously incorrect. You want the officials to take it to heart when you point something out, because they know that you're probably right.
