If 49 old Wladimir Klitschko came back from retirement..

...challenged Usyk and knocked him out...how great win would it be?

[Coverdale]

It would surpass Foreman's achievement.

He seemed slow to me, even prime. Pace slow punches slow, jab and grab slow. Right now he has to be geriatric

Honestly, Wlad could move his hands pretty fast when he got them going considering his size and muscles. He's had some wicked straight right hand KOs that were really fast, not to mention a quick left hook. The hook didn't always produce the KO, but it has done knockdowns.
