ON A SUNDAY evening in May, the Accor Arena in Paris thrums. Thousands of fans scream and shout as Victor Wembanyama, the 7-foot-4 French teenage basketball sensation, warms up with a blizzard of baby hooks, casual 3-pointers and the occasional hammer slam.
As Wembanyama lopes through the layup line, he brushes past a man of similar height standing near the edge of the court: Frédéric Weis, at 7-2, is impossible to miss. Wearing dark jeans, a suit coat and tie and shiny Air Jordans, he is preparing to do color commentary on the game. He watches closely as Wembanyama goes through his paces.
