Wait.. Wlad easily KOed Mercer lol Are you going to mention Mercer's age since all of a sudden age matters?
He threw 36 jabs in the 12th round. Thats the highest number of jabs thrown in a round so your claim he only had one arm is false. He was throwing with both arms until the final bell.
"A doctor confirmed a ligament tear was suffered in his left shoulder. Klitschko said he "suddenly lost strength in the left hand" and was forced to only use his right. The injury was believed to have happened in the second or third round." This is what was reported in dozens of media outlets, if his shoulder was badly injured then his left jabs would have been much weaker. Ofc it could be just to save face.
When I saw this thread, I thought they were talking about my hair tonic, Vitalis. But I saw it again, I know what was asked. Lol.
The Klitschkos were lucky, that HW was basically dead during their reign. Imagine Fury, AJ and Wilder would have been active in their era.
Both prime Klitchskos would have destroyed Wilder, especially Vitali. Vitali would have KO'd him inside 2 rounds. Wlad would have taken his time and done it in 5-6 rounds. Wilder has about a 1/10 chance of winning against them. I also think AJ would get demolished vs Vitali, and prime Wlad would beat him 7/10. Fury is 50/50 against either Klit, all depends on which Fury turns up, and even then it's far from easy to predict.
