We'd have to consider him a week champion over a weak era. He beat Wlad, but at the end of his career. Wilder he beat three times but he looks more like a hype job over the course of his career. He's just gone life and death with a debutant. Not inspiring stuff.
If Fury retires beating Usyk, Zhang, Joshua and winning a rematch against Ngannou, then he will be an ATG or the GOAT. Even with the robbery yesterday. If he just retires now he will will be known as wasted potential.
