Please folks, discussing WC and US preformace in it as if it has anything to do with the NBA is sophmoric and pointless. Team US played to gether for exactly 90 days, not exactly the kind of time that is needed to practice a full book of plays, defensive assingments, rotations and then test them out in scrimages and warm up games. The Greek team played extreemly, they played smart team ball, but they are hardly a shining example of how and NBA team ought to or even COULD look and paly through out an full NBA season then post season.
NBA championship teams rely HEAVELY on outstanding players who lead the team no just in acts of scroing, rebounding and defending but with a serious presence that is respected and followed by the team. The list of these men is long but a few of the names at the top: Jordan, Magic, Bird, Russel, Cousey, Chamberlin, Jabar and Shaq ALL were much more than superstars, and their teammates knew it, respected it and followed them, in some cases even after they were in decline.
Muss may or may not beable to get the guys to paly well as a team, maybe even greater than the sum of the parts but unless a true outstanding leader emerges on the floor (possibly Artest) they will be out maneed by the top tier teams in NBA.
