Same height (6'3"), same reach (78"), same birthday (January 17). Both guys won a gold medal in the Olympics. Both guys became the heavyweight champ by beating a hard-hitting opponent with a longer reach. Ali beat Sonny Liston (84" reach), and Usyk beat Anthony Joshua (82" reach). Even their KO rates are similar. 66% of Ali's wins came from knockouts. That number is 67% for Usyk.
