[Most] boxers improve over time, do they not? Fury the dosser isn't really the same as the one coming in with a point to prove. Same goes for Joshua, what caught him a few years ago wouldn't now. Fury's style is the outlier in the division and huge challenge for heavier or muscular fighters, of which Joshua is both. If the fight ever gets made, I'd think Joshua will come in lighter than he's ever been as champ. I don't know what that'd do for his stamina, but it might offset some of the issues with his tank and give him a better chance of forcing errors out of Fury.
