Although it's been whitewashed because of his gold medal in 2008, LeBron played on the 2004 U.S. Olympic basketball team — known as the "Nightmare Team." They were the only U.S. squad to fail to win gold at the Olympics since NBA players started participating in 1992.
Yahoo's Adrian Wojnarowski also reported that LeBron was almost left off the 2008 Olympics team because "the issue of James’ immaturity and downright disrespectfulness had become a consuming topic on the march to the Olympics. ... No one could stand James as a 19-year-old in the 2004 Athens Olympics, nor the 2006 World Championships. Officials feared James could become the instigator of everything they wanted to rid themselves for the ’08 Olympics. For as gifted as James was, Krzyzewski and Colangelo subscribed to a belief that with Kobe Bryant joining the national team in 2007, they could win a gold medal in ’08 with or without LeBron James."
