Floyd Mayweather Jr. is on top of the world. He is the world’s highest-paid athlete and is headed for the biggest payday of his career. New estimates show Floyd Mayweather Jr.’s payoff for fighting Manny Pacquiao could easily be $180 million. Unlike other super-rich athletes like Tiger Woods and Tom Brady, Floyd is not afraid to flaunt his wealth. He posts photos of himself and his money (literally, stacks of money) all the time, and they are unreal.
