I look back at previous heavyweights, and I struggle to find very many heavyweights over the history of the sport that would have been these two at their best.

I think they would have steam rolled Frazier, Marciano, Patterson, Liston, Louis, Foreman. I see absolutley no way how these guys could get in on guys taller and stronger than them with that kind of jab.

I don't think Holmes and Ali's moving on the outside styles would be super effective because at least Wlad who is always in balance would walk them down with his jab.

Norton might present problems for Wlad because he is awkward, but Vitali would destroy.

Honestly besides Lennox Lewis I can't think of a fighter who even in their prime I would give a better than 50/50 chance against these brothers.

I also find it insulting or ignorant to say Wlad hasn't fought quality opposition in the last little run Ibragimov, Chagaev, Peter(at the time), Byrd, Brock, Chambers, and the list goes on were all highly competent fighters. But Wlad has great timing and highly underrated speed, and I can't think of a punch in the history of the heavyweight division that landed more consistently than Wlad's jab, and that jab lands like most heavyweights crosses.
