Exactly, they are not the dream team anymore, even the USA coach Mike Krzyzewski, who was an assistant coach on the first "dream team" says the only dream team was the first one.
Well, that's true, it's not for Mike Krzyzewski to decide, but team USA don't think they are the dream team, USA media don't think so either.
The first one is the orignal one, you can try to be like one, but that doesn't make you one. You can play like Tiger Woods, look like Tiger Woods, win more than Tiger Woods, but that doesn't make you Tiger Woods.
There is no team like the first one, and there will never be. I am not saying the first team is the best ever, or that no team can beat them, but the original team was the first unique team of its kind.
