“The Redemption Tour” ended in a familiar spot for Simone Biles: atop the Olympic podium. The American gymnastics star and her singular brilliance powered a dominant U.S. women’s team in the finals inside a raucous Bercy Arena. With Biles at her show-stopping best, the Americans’ total of 171.296 was well clear of Italy and Brazil and the exclamation point of a yearlong run in which Biles has cemented her legacy as the greatest ever in her sport and among the best in the history of the Olympics.
