Why did the 2004 NBA dream team lose in the 2004 Athens summer Olympics?

They were good, but not great. They were not disciplined enough, and they had talent, but just didn't know how to use it. Lebron was young in the NBA, and Iverson was good, but way too y. Dwayne Wade almost had to lead them, mentally and physically. Honestly, they needed a better PF. Boozer is decent, but certainly not a dominant player.
