I always thought Lewis would beat Wlad in a possible matchup between them, and the view of a fellow poster who has actually sparred with both of them confirmed my thoughts about this fantasy matchup. Lewis is way more versatile with his punches, has a better chin, never gassed out in fights the way Wlad has, always sought for rematches after losses and avenged every one of those, and also proved himself against better opposition. That said, Wlad is a tremendous fighter and he would always be a tough fight. I just think Lewis would beat him, would be a 65-35 fight for me.
Vitali has never in any point of his career been considered better than his brother. This stretches back to his AM days. You should pay more attention to the sport you follow.
Vlad would come out, timidly against Lewis, big mistake. Lewis would come looking to assert himself and his power. Where as Vlad would be backing up, and trying to figure out Lewis, pawing with his jab while fighting in reverse. Lewis would force it, taking it to him and once he starts landing that right hand... It wouldn`t take all that many to give Vlad a nice soft spot on the canvas...
I'd favour Wladimir 55/45. They are similar but Lewis was lazier and got KOed close to his prime when Wladimir rarely even gets hit in his prime. Also, Wladimir has more experience and fought a lot more fights, and Lewis never got up from KD to win a fight and Wladimir did it many times.
