We can’t know that. Usyk fights at the same weight but as prime Foreman. He’s slightly taller than Bruno. As with every sport, fitness and nutrition will see today’s athletes miles better conditioned than those ‘back in the day’.

For me though, if you were to face off all the great heavies against each other in their prime, Lewis wins. He’s the sweet spot between eras - had the size of modern super heavies but is unusually excellent technically and had great power.
