Well I guess if you want to see it like that Duran wasn't to tough against Leonard or Quarry wasn't so tough against Frazier but they were both tough *******s. Sharkey was teak tough. One tough boy.
I questioned the term shocking power which ,I believe the majority of posters would when applied to Jeffries punching ability.His major opponents Corbett,Fitz,Johnson ,ALL said Choynsky ,a super middleweight hit harder than him. Fitz and Choynsky were one punch ko bangers, on the whole Jeffries was not, he wore men down, and considerably lighter men, do you think 163 lbs Fitz could go 11rds with Wlad? Was Ruhlin down in their second fight? Armstrong was not floored by Jefries was he? The Chambers/ Wlad analogy is a bad one because. 1. Chambers is a full fledged 210lbs heavyweight NOT a 183lbs man as Sharkey was. 2.Chambers fights defensively ,Sharkey was a face first, come forward brawler. Foreman fell face first against Lyle ,yet got up to ko him. Bags dont hit back.
