Floyd Mayweather Jr

Floyd Mayweather Jr.: $300 million 

Those in the public who spend big bucks to watch his fights may not like it, but all were reminded in 2015 that Floyd Mayweather Jr. is not in the business of putting on entertaining shows inside of boxing rings. His business is winning fight after fight however he can do so, and business has been profitable for Mayweather during his career. Those who would suggest that boxing is a “dying” sport should examine Mayweather’s bank accounts before voicing such hot takes. The sport can still be an international sensation with the right act at the top of main events.
