IMO, people are giving too much credit to the coaching in this thread. I don't think the X's and O's matter that much at this level. What does matter is the at ude of the players on the team...at least the members of the USA Team anyway. We've got 2 guys, LeBron and CP3, who are looking to pass first even though they are tremendous scorers in their own right. When your best player (LeBron) is looking to pass first it can't help but infect the team with a "team first" at ude. Coach K is doing a good job, but without LeBron and CP3 promoting the "team first" at ude it wouldn't matter.
When you have the best talent in the world and the team is playing unselfishly you cannot be beat.
