AJ and Cuban, for starters. There's the Dairy Queen game, the "Manu flopped into Dirk" series, the "bear hug defense", the "Terry shouldn't be suspended" game. Let's not forget "Timmy gets all the calls" and "Dirk gets no respect" just for good measure. , I remember Sean Elliott hitting two free throws with nothing on the clock to win a game against the Mavs and all they did was complain, and that was before Mark Cuban.
If you'd like not to be lumped in with the other Maverick fans, you could distinguish yourself by not blindly defending all things Maverick. If you can't accept that the majority of the country and the world sees the Mavericks as a bunch of crybaby sore losers, then you have need of some perspective.
