Probably still Wilder, if you could get him to throw it. Then maybe Bakole, then maybe Dubois. Joshua never had one punch KO power.
Wilder or Dubois. Wardley is one to watch when it comes to right-hand power though. He is not very skilled but he is super tough and can really crack.
I don't like Okolie but he can actually hit very hard. Along with Riakporhe which is impressive as they were CWs for a while.
He landed it against Parker and Zhang to no effect. His right hand is gone. They changed his style and now he kinda doesn´t know how to load up on that right hand like he used to, plus his reflexes are gone, which were a big part of his success.
Well, that and when he's not against crap opponents he doesn't have space to load up on it, and having taken some beatings might be scared to risk it... Plus hasn't been fighting his traditional mediocre fighters who are incapable of backing him up.
Dubois is the heaviest puncher out there now, and he can land. Wilder is all washed up since the Fury 3rd fight where he took a life changing beating.
I agree, people forget that Dubois threw loads of right hands on Hrgovic and he never looked like he would go down
Zhang's southpaw right hook might top any right hand of an orthodox fighters. He KOed granite-chinned Joyce with a single right hook, dropped another iron-chinned fighter in Hrgovic, dropped durable Parker (2nd knockdown) and KOed Wilder - all with a right hook
