Yes, 190 pounds Joe Louis would beat him 6x via black & white footage witchcraft.
Stupid question tbh, who can tell? It would make more sense to talk about who could beat him if they fought each other once, prime for prime.
Obviously Lennox could
... I think Riddick Bowe could if he showed up motivated and hungry
... Ali's mobility would be a real issue just looking at round one of Vitali vs. Herbie Hide
... same goes for Larry Holmes, who had fantastic feet when you look at his fight vs. Leon Spinks
... Tyson/Foreman would be fights for the ages, it would be better than Foreman vs. Lyle due to the aura, presense and determination that Vitali brings
... Evan Fields is hard to pick against, but not unbeatable himself either
... Liston is the one I'd feel comfortable to pick against, I think Vitali smacks him around.
... Frazier is missing, because despite his size disadvantage he was a savage in his prime and a tough fight style wise
However, Fury has no business being lined up in that list.
