Joe Calzaghe
Calzaghe is retired now but during his prolific run (46 – 0) he was one of the most underrated fighters in the world. Calzaghe has the pleasure of owning the longest run as a Super Middleweight Champion in the history of the title — having held the title for an entire decade. Calzaghe is enjoying his retirement now and we doubt he’ll have trouble scoring car loans online with all of those victories.
Anthony Joshua
What hasn’t this British professional boxer achieved in his 28 years? Oh, folks, his list of achievements is endless. Currently, Joshua is a unified world heavyweight champion, a title he’s held the IBF since 2016, the WBA (Super) and IBO titles since 2017, and also the WBO title since March 2018. Of his 21 fights to date, all but one were finished by knockout. The Ring, the Transnational Boxing Rankings Board, and BoxRec all rank Anthony Josuha as the world’s best active heavyweight.
