We all know what Fury is capable of doing in the ring but now he has the added motivation of being a unified undisputed heavyweight champion if he can get past Wilder again and if can beat the winner of Joshua vs Usyk II. Even if Usyk defeated Joshua again then managed to put on weight, he will be no match for Fury.
I think that in order to be able to seriously talk about the Fury - Usyk fight as a competitive one, it is necessary that Usyk gain at least a little weight (can he, given that he has already moved to a new weight category for himself?). Now Usyk weighs 100 kg, and Fury 123 (or already more) - 23 kilograms of difference, in fact, they are in different weight categories.
