I think Sonny beats any of them in his first fight. On a one fight basis he beats Bowe and Klit, maybe Tyson. But winning big once would be it and Whoever is next will beat him. I say this because Some of Sonnys strongest supporters say Liston was already an alcoholic by the time he rematched Patterson -and that even then-he was still good enough to beat the 30lb smaller psyched out former champion. The guys here are not 30lb smaller. Or psyched out. So I believe his performance would suffer. Overall though, these champions are very evenly matched. I favour Tyson to win a tournament, not because he was unbeatable but because he was more consistent. We saw Wlad crash against Sanders and Brewster without getting the kind of run together that Tyson had over Berbick, Smith, Thomas, Holmes, Tubbs, Biggs, Bruno, Williams
I'd put consistency down as a trait that Wlad had an abundance of in his prime. He was clearly a much better fighter after he suffered the Brewster loss, in fact Liston for the most part was probably more consistent than Bowe and Tyson as well.
I don't know if he was an alcoholic, but he was certainly in the booze by the rematch according to some of those closest to him. Anyway, you're half right with some of this. Liston had a very bad reaction to winning the title. Some say this was because he was "rejected" as champion when, up until that point, he had believed that winning the title was going to solve all of those problems. Others think that he just didn't have the mental strength to continue on from the summit. This is seen a reasonable amount in fighting (Buster Douglas might be the best example), the former is a widely held opinion. You are literally the first person i've ever read to insist he had one huge fight in him. Primarily it'll be based upon wishful thinking, of course. My own guess is that if Sonny had to win the tournament to win the title, you'd get the best out of him for the entire tournament. I don't know if that would be enough to win it or not because it's some serious company. But there's really no real world reason to believe otherwise, just your weird Liston fantasies. On the other hand, if he beats, say, Bowe and wins the title but is expected to defend his title as a part of the tournie, then that's maybe a problem for him. Or it might depend on circumstances, we don't know. The strangest thing about this post is to learn that "best for best" you believe Liston to be the best of these fighters.
Liston is not beating Wlad. Not with his footwork or his size deficit. Liston was the size bully in most of his fights he’s losing that advantage here to 2 of the 3 opponents. Bowe however didn’t fight tall or use his advantages so Liston could beat him. For me Tyson or Wlad win this. Bowe didn’t face great punchers or really great jabbers during his career. Had a porous defense as well. He isn’t getting through this gauntlet. Tyson 87-90 was dominant Wlad 06-13 was dominant I think it comes down to them and it’s a toss up on who you prefer style wise.
But that's not Wlad at his peak which this hypothetical competition demands. He, Wlad, also went on a run of victories which included Byrd, Brock, Austin, Brewster, Igbragimov, Thompson, Rahman, Chagev, Peter and Haye all of whom bar 3 had held or would hold a major Heavyweight belt. I'm not saying that Wlad fought in a golden era or many - if any - of those names will be remembered beyond the boxing hardcore in 50 years time, but they represent most of the best of the generation and the only significant name missing is Vitali Klitschko: a fight that was never going to happen. A peak Wlad has one of the best jabs in Heavyweight history and if there was one type of fighter who was destined to cause Tyson a lot of problems, it was one who had a great jab. There is always the possibility that a peak Tyson lands something heavy and Wlad falls apart, but a peak Wlad seldom got hit flush because he developed a style that made it next to impossible for his opponents to do so.
what’s so strange about that? I have always said Sonny was a great fighter. Head to head, he fights how a great fighter should. Great hook. Great range. Dangerous at both ranges. Two handed power. So many assets. Even when defending Marcianos chances against him I have always said Sonny should be favoured in the odds, that rocks chances would be a long shot, against those odds. The thing with Sonny and other fighters that really demonstrated excellent qualities on film is that it is against less great fighters than other Champions did. His resume is thinner than some who did not quit and had less physical advantages more often than he did. But on a one on one basis, head to head, using his best performance each time I have never believed too many would beat Sonny. Some could. But it is a short list.
I mean your mis-interpretation of Sonny's difficulty with alcohol etc. rather than your prediction in the tournament. In a fantasy tournament, no, nobody can even be half right.
