special mention to Deontay as well, he has a lethal 1-2 with a right hand down the pipe
i think with Klitschko, he was fighting for so long from such a young age and his frailties he had when he was younger always stuck with him, even though he never fell to pieces for the majority of his career, he looked affected by something early on and seemed to have stamina and punch resistance issues, these seemed to leave him when he got with Steward and fought exclusively in Germany, make of that what you will but he was almost like a different fighter
