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 this is the only tactics to defeat Usyk. Going full distance or allow Usyk to work his tempo is a one way ticket to loss by points in the end. I think the best tactics would be aggressive start without saving stamina for late rounds. All or nothing from the start. Push and crush from the start, and if it fails, it will be a UD loss anyway in the end. If it is hard to outbox him, then outpower should be the solution. His body isnt a concrete, he cant hold heavy punches forever.
