Salary/Winnings: $20.8m Endorsements: $44m The future of the basketball world may belong to Kevin Durant, but there's only one undisputed king of the here and now - and that's LeBron James. The Ohio native has already established himself as one of the greatest ever to play the sport, but remains hungrily in search of his third NBA Championship - preferably with his hometown Cleveland Cavaliers. Of course, James' contract is huge. As well as a two-year deal worth $42.1m, he is set to become a free agent this summer (when the NBA's new TV deal begins, and the players' salary cap subsequently rises). He also collects lucrative endorsement deals for fun, including Nike, McDonald's, Coca-Cola, and Beats by Dre.
