Wanna Get to Know Ya (II): Floyd Mayweather is boxing's "bad guy." The bravado, endless trash-talking and flaunt of wealth, and legal troubles make sports fans either love him or hate him. But regardless of their preference, they tune into his fights. Over the last decade no boxer has averaged higher revenue for his fights than Mayweather. It isn't all about his showmanship, though. Behind the cocky persona is arguably boxing's most dominant fighter of this era. He was born into a boxing family with his father Floyd, Sr., and his uncles Jeff and Roger Mayweather, all having careers as pro fighters. Ever since he won his first title at the age of 21 (WBC Super Featherweight belt), Floyd has been dominating the sport with his trademark elusive fighting style. And when we say "elusive" we're not talking about him ducking Pacquiao. We see you, Pacman fans.
