No the ref stopped the fight, there's a difference. And the point still stands 1. Joshua has beaten Ruiz and also beaten better than him and Dubois. 2. Dubois would get obliterated by Ruiz 3. Dubois' best win is Bryan.
The referee stopped the fight because Joshua spat out his mouthpiece, which many fans disregard, but is against the rules, then took a walk to his corner, waiting for his English tea - sorry, but the stoppage was correct. He had his rematch, won it being wiser, but also fearful.
The ripple effect on this board would be amazing. I can't even imagine the threads. Hell, Gassiev lost every round to Usyk, but Oleksandr's "aura" is such that people on here were picking Murat last week to stop a "prime" Mike Tyson. Overnight, Dubois would become, for some, the greatest of the greats. He'd "have to be." It would be the only way to explain the win.
