I've never heard anyone yell, "you know we fired our last OC".. I have heard fans boo a play call and the officials. Big deal. I have heard some boo's over crappy play after lots of frustration. Many fans will "criticize" a play or player for messing up. I'm not sure what's wrong with that. Not sure I've heard many complain about their seats.

To be honest I don't pay much attention to anyone except my family around me and a few people who have sat by us the most. I don't get caught up in what other people are doing. Sure I joke with my BIL about some peoples lack of knowledge about the rules, but not enough to be upset after a game. Stop worrying about everyone else and just enjoy a game.
