Cuban is classless. You agree to do the interview, stupid/annoying/cliche questions are a given. Why be an ass about it? I would think it'd be easier to be nice and say "Ask a better question". If you're not in the mood for an interview, don't agree to one.
I don't think that analogy works. It's not like he turned the corner and was suddenly surprised to find a group of reporters in his office. He should understand the process...hell, he likes to create his own media chatter, you'd think he'd be pretty well versed by now. I'm sure there are plenty of times they won a game and was asked a pretty standard question. Something tells me he didn't cuss the guy out then. He was pissed off, and acted like an *******. There is little excuse for acting like an ******* to people who have nothing to do with your problem.
Cuban is an immature ass. He justifies his poor behavior as a noble gesture to the league and mankind to rid the world of bad officiating. In reality, he's a big titty baby who can't control himself when things don't go his way. I can't see how people spray perfume on his dog crap antics and pretend that his antics don't stink anymore. He's not a great owner. He's a guy with a lot of money who thinks he's above the rules.
