I still have questions if Anthony Joshua can still be able to go through wars in a long fight. His last 4 fights after the Usyk lost really didn't answer that
In the longer fights with Franklin and Helenius, he looked extremely uncomfortable and very unsure of himself. The Ben Davidson addition to the team should help though. Because of this, I think Joshua has to end the fight in under 6 rounds because that's where he can be the most dominant against Dubois
Dubios on the other hand will have more chance to win the fight as the fight goes in the later rounds. He has shown to be way more comfortable to have a better stamina and mental fortitude in the later rounds. IMO if it goes past 7 rounds, I got Dubois winning this
