Which heavyweight had the most power?

[Luilun]

Wilder shouldn't be on the list until he starts fighting and stopping Top 10 fighters. Any Heavyweight who's considered elite would have 33 Ko's if they fought Journey Men for a living

Cannot rate Wilder & Joshua until they prove it against better competition.. Manny Steward said between Lewis & Wlad, Wlad was the better boxer & also had 1 punch KO power but he is also very reluctant in executing it..
Ernie Shavers was the hardest hitting as per many old greats but not a 1 punch KO.. Prime Foreman, Tyson & Wlad stand out imo..
