the common perception around the league is that when cuban whines it ultimately backfires. I guess you can look for evidence in the amount of money he has paid to the NBA. Nate Mcmillian got fined 35K for his remark earlier....if it were cuban it would have been 100k.
Phil Jackson is one that actually said whining to the press causes the officials to get personal and ultimately leads to calls being emotional. He even eluded to mark's ranting leading to dallas getting hurt against miami in the finals by the officiating. Other professionals(not fans) have also said this hurts dallas with officiating. Look at the joey crawford stat. Dallas is like 4-13 in playoff games that he calls.
I don't know about portland, I will say that in the 4th quarter of the last game the calls went their way. However, they were more aggressive than dallas. they outscored them in the paint 18-0 in the 4th. that is inexcusable for dallas and is why they lost.
In this game dallas was aggressive from the start. Chandler was finally a beast. Dirk attacked the rim a lot more than previously. Marion also got into the paint. Dallas scored about half of their points in the paint, which for them is very good. I'd say they got to the line a lot because they were aggressive.
