I think people (read: the media) are crowning this USA team WAY WAY WAY too early. What is significantly different from previous disappointments? Team thrown together, supremely athletic and gifted, lack of perimeter shooter, etc. That is still Team USA's make up. Maybe having Kobe, LeBron, Wade, etc play major roles is enough this year... only time will tell. But either way, I think it is going to be much closer and competitive than most people (read: the media) are leading us to believe.
When it's close and late in a big game, will Team USA know how to react, where to move the ball, and who will shoot? You better believe Argentina, Spain, etc will. I kind of see it as a Celtics-Hawks type thing... one team is clearly more talented, but that team also hasn't been through those paces and situation together before.
