Last weekend’s Heavyweight Championship fight between Deontay Wilder and Tyson Fury has been hailed as one of the best for years, and with Anthony Joshua holding the other championship belts, there are echoes of great rivalries of the past: Evander Holyfield, Lennox Lewis and Ruddock Bowe, even the ‘golden years’ of Muhammad Ali, Joe Frazier and George Foreman. This of course prompts the age-old and agreeably futile question: how do today’s champions rate when compared to past ones? It’s a game that most sports fans play, picking their best of all-time team and so on. Back in the late Sixties it even spawned a computer-generated fight between Rocky Marciano, the champion of the mid-Fifties, and Muhammad Ali. I remember watching this bizarre affair, though I can’t remember who the computer decided should win.
