Floyd Mayweather Jr.'s dirty tactics and foul mouth land him on the list of top 25 bad boy fighters of all time. He joins a list that includes fighters who were beasts in the ring, fighters who've led lives of crime, and fighters who simply don't know when to keep their mouths shut.
The list is long, but every man on it deserves to be there for one reason or another. Without them, the sport wouldn't have bad guys to root for.
Compiling the list was not easy, because there is something bad in every boxer.
These guys, however, showed exceptional "bad boy" power, as they've made a name for themselves in the sport for their abilities to intimidate.
