Very tough. Ali, Holmes, Holyfield, Charles, and Walcott would all be top picks for me, but I would actually have to say Joe Louis, even though I don't think he was as good as the others. But power-wise, Louis was also a good boxer. Ali, Holmes, and Holyfield check most of the boxes, but I don't think qualify on power. Charles and Walcott do, but Louis hit harder than all of those guys.
For 3 or 4 years Mike Tyson was unbeatable. Only poor life choices, bad advice & hangers on stopped him eclipsing Marciano’s record. For longevity probably Larry Holmes.
Joe Louis nails everything for me. Ali and Holmes are up there. Charles was a sneaky good pick as well. Holyfield.
Muhammad Ali, he had longevity, he brought a style that had been not seen before. He had charisma, he had footwork, reflexes, stamina , and blinding speed in his prime years, 1964-1967. He fought against his challengers in their backyards. He was very vocal and spoke with intelligence. He was not afraid to stand up for what he believed in, he was willing to sit out 3 and a half years for what he believed in. When he returned in 1970, he had lost his prime attributes but figured out other ways to win, he was resourceful, and in 1974, it worked, beating George Foreman to win back the title that he never lost in the ring, only to Uncle Sam.
I agree and disagree. Part of being well-rounded, to me, has to include longevity, resilience and other intangibles that the very best of the best displayed. Skillset alone won't always win a fight, sometimes you have to bring the inner-Ares out and be a God of War. Tyson wasn't proficient at all ranges, predominantly being a mid-range fighter. His temperament and the issue with entourage, the rapid decline of his skillset post-Rooney and post-prison antics make a lot of people overegg the criticism when hypothesising H2H, but still, his frailties are a very real factor.
No he doesn't. Ali checks these categories: Hand Speed, Footspeed, Durability, Endurance, Ring Generalship. But he doesn't check these categories: Power, Defense, Killer Instinct. Mike Tyson is the closest one to perfection.
