Usyk has lost some speed and his legs aren't as good as they were 4 or 5 years ago but he's compensating for it in other ways. You could even argue that he's never looked better at heavyweight than he did in his last fight. He didn't get hit and KO'd his opponent early. Now that he's really starting to sit down on his shots he's hurting guys. Men that are much bigger than himself.Usyk hardest fight thus far vas then prime shape Briedis.
Usyk is relatively long ago over the hill and out of physical prime. However Uncle still is considerably more mobile and " fresh " than Parker.
