Joshua tried to outbox Usyk and failed, he also didn't let his hands go, he was discouraged. Dubois will take more risks and even rush, he is aware of his strength and will try to use it.
Let's hope Dubois uses his strength because that is the only attribute he has more of than Usyk has. If he doesn't he will be schooled. He may get schooled regardless.
Dubois hasn't beaten anyone notable. He is at most a domestic level champion. He was embarrassed by Lerena. He isn't even in the same league with Usyk. Usyk by KO in round 8.
