I'm not talking about their conduct towards other countries players... sorry that was not clear. I don't have a problem with their on-field behavior.
The concept of the "Dream Team" is my problem. Other countries athletes train and practice together to build a team for the pride of their nation. They see themselves as a team, with all the chemistry and sense of identity that a real team has.
The so-called "dream teams" of the U.S. on the other hand, pluck a bunch of players from different professional teams and put them into a "all-star" type team. The members are selected because of their names and reputation from the NBA, not because they have the skills needed to create a balanced national team. The whole intention of creating a team like this is to provide "stars" for the American viewing public to watch humiliate the international teams (Why else would the two losses this year cause so much consternation in the media and fans?)
That's what I mean by bullies. They're not a team but a collection of ringers, who must win the gold or be a dramatic and complete failure.
I would cheer wildly and support wholeheartedly a true U.S. Men's National Basketball Team. A team that had the same players on its roster for several years. A team that regularly competes in international competition between Olympics. A team with players chosen because of their ability to help our country's team win, not because of their superstar status in the NBA. A team that is meant to represent my country, not one who only reflects the star-power of the NBA.
