It's not that Joshua is musclebound that would worry me about his stamina, it's that he fights with his shoulders and back kind of tense as he wants to land with power on every single one of his punches. And that is what reminds me of Bruno about him, that tension eats up energy and will sap you real quick if you're in there with a guy who is pouring on the pressure. Anthony Joshua needs to loosen up and relax and also learn to tie up. I think his talent is much better than Tyson Fury.
