Probably Liston. Michael Spinks, sadly. Both are examples of what the typical "man in the street" would remember, not so much classic boxing fans.
Yaqui Lopez to Saad Muhammad. Yaqui an excellent contender who was robbed against Galindez earlier. Also Flash Elorde to Saddler via cuts. Zamora vs Zarate = Z war, since Boxing corruption prevented this unification bout, Zarate was seen as 'Undisputed' to the general public/media once he beat Zamora. Also remember that notable fan who jumped in the ring lol Quarry vs Frazier and Ali
Andrew Golota. The bizarre losses to Bowe, getting blitzed by Lewis, folding against Michael Grant and being obliterated by Brewster in seconds is basically all that you think of when it come to him. Pat Cowdell is a bit of a fall guy too. You really only remember the narrow Sanchez loss and getting iced in one by Nelson. It’s a pity because he was a very good boxer who happened to meet two absolute legends in their respective primes.
Michael Spinks. How bad it must suck to have such a great career... to only be remembered as the dude who Mike Tyson KO'd in 1 round.
Big John Tate Won the WBA heavyweight title vacated by Muhammad Ali in 1979 by beating Gerrie Coetzee in South Africa and was seen by many as a serious rival champion to Larry Holmes who had won the WBC belt in the previous year. Shocking back to back defeats against Mike Weaver and Trevor Berbick put paid to any eventual matchup talk with Holmes and in reality his career never really recovered. Finished his career with a 34-3 record and sadly his personal life unravelled after his fighting days were over. Got into trouble with the law and served time before he was killed in a car accident in 1998 at the age of 43.
Andrew Golota definitely. Ron Lyle vs Foreman, putting George down twice before being stopped. Earnie Shavers in his title fight against Larry Holmes, putting Holmes down with an unbelievable right hand, but getting stopped in the 11th.
Hate to say it because I’ve always like the guy but you could put Kenny Norton’s name in there. The two close split decision defeats against Muhammad Ali and Larry Holmes in 1976 and 1978 plus the two devastating knockout defeats against George Foreman and Gerry Cooney are probably what most stands out in people’s memories when they think of Kenny.
