I don’t know, something tells me Dubois will jump on Usyk from the opening bell and try to turn it into a slugfest, which Usyk will likely try to avoid.
I think the best tactics would be aggressive start without saving stamina for late rounds.
But Dubois isn’t agile enough to stick to this tactic from the start to the end of the match. It’s more likely that he’ll be the one completely exhausted, not Usyk. Heavy punches to Usyk’s body might be a more effective approach. His trunk has proven to be something of an Achilles’ heel. If Dubois can take away Usyk’s breath, he might be able to break through at least on the scorecards. Still, I believe Usyk is well-prepared for this clash, and I’d probably bet on his win.
