Dubois definitely has a shot because of his high KO rate, but he needs to fight smart, not reckless or Usyk will capitalize again. After the controversy in their last fight, you can bet the refs will be keeping a closer eye this time. Low blows probably won’t be tolerated anymore… unless, of course, they plan to rig it to make sure Usyk stays champion and retires with all the glory.
Dubois is younger and
[erhapsperhaps more explosive but I think Usyk is still faster and definitely technically better. Dubois will have to come up with something to surprise Usyk and will have to take some risks, even it that means exposing himself to getting KO'ed for the second time. I don't see much chance of Dubois beating Usyk by decision, unless he manages to score a knockdown or two.
But his best bet would probably be smartly managing his energy and exploding at the right moment, possibly to counter Usyk's actions.
I don't expect the fight to go the same way as their previous one. Usyk is not resistant to aging, so he must've lost some of his speed/agility, while Dubois got some more experience and probably matured a bit as a fighter.
