Now? All time? Byrd did cause VK quit. Lewis legit TKO. I am sure there are others who could as well.
who could beat vitali hhhmmmmmm is he allowed his steroids? roided vitali got broken down by byrd and smashed old man lennox. without his steroids sanders would have gotten him out of there too, and lord knows if he would have even won a title
Please specify the question, do you mean currently active boxers? I don't think anybody could, Fury would probably give him some trouble due to his size, but prime Vitaly could deal with it. All time, plenty of people. Prime Lewis, maybe prime Holyfield, maybe prime Tyson, Ali, prime Foreman, etc. He is a borderline top 10 ATG heavyweight, I repeat, borderline. Someone with a really outstanding speed / power / size / stamina combo with decent technical skills could beat him.
border top 10? at doing what coz it aint boxing. back here in reality beating danny Williams and sosnowski and getting stopped by byrd and old man lewis makes you a fairly average belt holder
Give me 10 names who you think would be a clear favourite to beat prime Vitaly and then we can discuss.
