Unlike the opening ceremony, when athletes march in with their national delegations, Olympians attending the closing ceremony file into the stadium en masse, symbolically suggesting that we are all one. (In practice, teams do tend to cluster together.) Elana Meyers Taylor, whose third place in the two-woman bobsled on Saturday gave her medals at four consecutive Games and made her the most decorated Black Winter Olympian, will carry the American flag. She had missed out on the role at the opening ceremony after testing positive for the coronavirus days earlier.
