Joshua knows that 2nd wind is there now, around a corner down the hall, if he finds himself emptying his 1st tank as long as he does the work. Gonna be tough to beat. To get that out of shape after winning the title, that's a lot of chaos, & not in Fury's favor, aside from how they match-up even if he lives clean & orderly. Gotta give him this, if you saw his "Fat HW hitting bag back in camp" vids: he looks better hitting mitts & the bag when obese than Fat Ricky Hatton.
They probably match Joshua with Fury 1st, because it's the easier fight, but him vs. Wilder is a good FIGHT. IMO Wilder tries to make it a bull fight and play matador, but that would be some shyte to see.
