7 sports stars you didn't know had criminal records

#4 Floyd Mayweather Sr.

Floyd Mayweather Sr. was an American welterweight boxer in the 80’s, and was renowned for his defensive ability and overall knowledge of boxing strategy. He is the father and trainer of five-division boxing champion Floyd Mayweather Jr., the world’s richest athlete, and is credited for teaching his son the defensive skills that made him a champion.

Unknown to many of Floyd “Money” Mayweather Jr.’s fans, his father served a five-year term for drug trafficking when his son’s career was still in its nascent stages. Mayweather Sr., and several others were convicted in 1993 of smuggling cocaine in detergent boxes from 1987-92.

This incident is said to have spurred his son on at a time when he was challenging for a berth in the Olympics.
