Who will follow in some of the legendary boxers who retired unbeaten namely Floyd, Calzaghe, Ward and of course the late great Rocky Marciano. Feel free to mention any others mot listed, Okolie…Josh Taylor, Bivol, Beterbiev etc
If Inoue keeps challenging himself like the way he's been going, he will get beaten sooner or later. Best shot at being undefeated is probably Crawford as I see him beating Spence if the fight happens and he will probably retire right after.
Eventually someone is gonna come around whose mother identified as a man, then Fury's prophecy will be his undoing.
In all honesty in the last 20 years it is only cherry pickers like Mayweather and Calzaghe that retire undefeated. Andre Ward retired young and should have a loss to Kovalev.
