This is one of my concerns. Usyk is pushing 35 years old, lets say AJ vs Usyk rematch will happen in March 2022, he'll be 35 by then. He'll probably fight Joyce if he beats Joshua again, in September - October 2022. Then he'll fight for the undisputed vs Fury most likely... that would be in April - May 2023 At that point he'll be 36 years old. Usyk is a guy who relies on reflexes, speed and footwork... attributes that start declining after the age of 32-33. I'm worried Usyk might decline noticeably in the next 18 months. It's a pity he didn't move to HW 2 years earlier.
