U.S. Olympic flag-bearers: LeBron, Phelps, Bird, Staley, more - ESPN
During each Olympics opening ceremony, each country's team is led into the event space by an athlete or delegation representative bearing his or her country's flag. On the U.S. side, the flag-bearer is usually chosen by fellow athletes and/or team captains. The practice of carrying flags into the opening ceremony began with the 1908 Summer Games in London.
