Could any heavyweight in history could Have KO Vitali??if yes who and how?

Well if your talking about the 6 foot 8 inch overgrown baby that QUIT ON THE STOOL because his "shoulder was hurting" in a title fight. If you mean this "delicate fella" that only had to hang in there with a very soft puncher for 3 more rounds to retain his title. BUT SISSIED OUT because. his "shoulder was bothering him" awwwww. Well Knight if your talking about that tall "delicate fella", you don't have to worry about KOing him. He may just get a hang nail that starts to irritate him and QUIT on his own!
