But if Barcelona was blessed with the presence of the fabled "Dream Team" - think Michael Jordan, think Magic Johnson, Larry Bird, Charles Barkley and Karl Malone - then the crowd of 11,560 crammed into the Helliniko Indoor Stadium saw a nightmare unfold for those wearing the Stars and Stripes.
The pain of a nation was captured in the grey face of head coach Larry Brown, a 64-year-old who is more used to savouring the upside of history. Just this summer he led the Detroit Pistons to the NBA Championship-with an emphatic 4-1 final series victory over glamour-side LA Lakers. Brown is also the only US male to win Olympic gold as a player, in 1964, and as a coach, being team assistant in Sydney.
Some time before tip-off against Puerto Rico Brown had recalled his Tokyo triumph with genuine emotion. "One of the best things that happened to me as a player was representing my country and winning the gold medal," he said.
"To me, representing your country is an unbelievable honour, but also an unbelievable responsibility."
It was a responsibility shirked last night by the likes of Allen Iverson, the flamboyant Philadelphia 76er, and Tim Duncan, USA Basketball's Male Athlete of 2004, and the lauded talent of teenager LeBron James.
This was a team of champions, but it was not a champion team. Brown swallowed hard and admitted: "I'm humiliated. Not for the loss. I can always deal with wins and losses. But I'm disappointed because I had a job to do as a coach, to try to get us to understand how we're supposed to play as a team and act like a team and I don't think we did that. Coaches should coach execution but never effort. That should be a given. But I'm truly not surprised. On the first day I got with this group I knew what was in store, basically. I'm angry because the mentality of our team was like this from day one.
"Now we're going to find out if we're ready to truly become a team. From our perspective the only thing we can do is find out what we are made of. This is a great opportunity for a group of guys to get together and figure out what it means to be a team. I'm anxious to see if we'll be able to do that."
Dwyane Wade, star guard with Miami Heat, offered no excuses. "We came out flat, dug a hole for ourselves and didn't make our shots," he said. "We have a lot to learn from this game, and I hope we can apply it in the games to follow."
The United States' next game is tomorrow. And the opposition? Only the host country, Greece.
If there is heart in his side, Brown had better get it beating. Quickly.
