In the Davis Cup and the Laver Cup, being the captain of a team is a big responsibility involving a good deal of strategy and seriousness.
In the new, season-opening ATP Cup, though, the role is a little bit different, and is set to be filled by names ranging from Boris Becker to Apostolos Tsitsipas (Stefanos' father) to Grigor Dimitrov.
