Floyd Mayweather and Aaron Chalmers are two very different athletes, hailing from vastly different backgrounds and competing in entirely different sports. Mayweather, widely considered one of the greatest boxers of all time, has an undefeated record of 50-0 and has won titles in multiple weight classes. Chalmers, on the other hand, is a former reality TV star who made his name on shows like Geordie Shore and Ex on the Beach, before transitioning to professional mixed martial arts (MMA) in 2017.
