Your level headedness might be more persuasive to the forum if you posted your reasoning, evidence, and arguments for your positions more often.
The only fighter at heavyweight who's style and physical attributes that would give him an advantage over every other heavy would be Ali in his prime. His combination of speed, endurance, skills, size and mental toughness are his keys. His most difficult opponents would be Tyson and Frazier, and he beat one of them twice. So Ali would be my number one choice. The rest are. Holmes Lewis Foreman Liston Tyson Frazier Holyfield Louis Bowe.
Yes you were, literally wrong. You supported opinion that Langford fought in bareknuckle stance and he didn't.
The Fantastic Five, i'd expect nothing less from you. With Liston and Louis next or thereabouts we'd have one helluva bunch.
Marciano is the toughest and mosg determinated, he knocked bigger guys out as Louis, Walcott and Ali. Johnson is master is tactic and has the highest IQ; he take Hopkins and Toney to school. Tunney is the smartest and slickest, his defence is brilliant. Lewis and Tyson are mentally not strong enough and were too slow, also had many whole. But I forgot Ruslan and Juan Carlos, which could win against many of the older ones, also "The Sniper" who would destroy Fury, Joshua and Wilder in one night.
My picks for the ten best h2h in chronological order Joe Louis Sonny Liston Muhammad Ali Joe Frazier George Foreman Larry Holmes Mike Tyson Lennox Lewis Riddick Bowe Wladimir Kiltschko
Barring a freak punch Lewis has a good chance of beating everyone while Tyson also loses to Liston and Foreman.
Tyson I'd favor over Frazier, Lewis? he never had anyone who'd be in his grill like Frazier and if he did drop Joe he ain't keeping him on the mat. In a 15 round fight Frazier gets stronger and Lewis wilts late.
