Espinoza: Floyd more likely to fight in MMA than the boxing ring

Is Floyd Mayweather Jr. actually serious about competing in MMA? No one's really sure, but Showtime general manager and vice president Stephen Espinoza thinks it's more likely we see Floyd in the Octagon than the boxing ring. Espinoza, who was influential in booking last year's boxing megafight between Mayweather and Conor McGregor , told Steven Muehlhausen of Sporting News that 'The Best Ever' loves a challenge and has already proven himself in the boxing ring.
