The first few rounds he doesn't overly exert himself (typically), plus the guys at HW aren't typically notoriously high output fighters anyway, so I still think he'd be fine at 35. Fury-Wilder will almost certainly generate a rubber match and then they'll have to defend against Whyte anyway. So I still think AJ-Usyk happens before he even contemplates going in with either of the other two.
Chisora would hurt dubois and joyce for me mate. People are falling into warrens trap with dubois. He looks great cause hes not fighting anyone. The only one hes beat is gorman who,s had pretty much zero decent wins himself. Had no great amatuer career. Hes gonna be good but people will see holes in his game when he does step up. Hes too green to beat chisora atm. Joyce too slow. Chisora would catch and hurt him. Tbh i think chisoras on something since hes been with haye...hes punching harder. A good bit more athletic. And yet hes getting older. Regardless tho...hes a seasoned proven heavyweight. Usyk will beat him....but he,ll make usyk work for it imo. I dont think chisoras a gimme for anyone. Pushed whyte all the way. A guy that until his last fight was rated in the top 5 or 6 heavyweights.
