Floyd Mayweather Jr.: Perfectly perfect

Floyd Mayweather is one of the greatest boxers ever, and is in his own division of greatness because of his impressive 50-0 record. Mayweather has effectively cleaned out the welterweight division time and time again. Perhaps the most impressive thing is that he continues to fight. Mayweather has accumulated enough money to retire multiple times, but he continues to put on strong performances, even against the toughest of opponents, like Manny Pacquiao. According to Mayweather, God only made one thing perfect, and that would be his boxing record.
