Vitali Klitschko
Currently, Vitali Klitschko may be the Mayor of Kiev but he’s a heck of boxer. He’s a three-time world heavyweight champion and also holds the second longest reign as WBC heavyweight champion of all time. What else? He even has the fifth-longest combined world championship reign at 2,735 days! Let’s not forget that he has the third longest individual WBC heavyweight title streak EVER at 9 consecutive defenses and also has the 4th longest combined title streak in post-war heavyweight history at 15 title bouts. Told you he was impressive.
Salvador Sánchez
From 1980 to 1982, the Mexican Salvador Sánchez was the WBC and lineal featherweight champion. Many people believe that if he hadn’t died young, he would have gone on to become THE greatest Featherweight boxer of all time.
