I think Fury's resume has taken quite a hit with the loss even if the last fight was close. Lets say Fury stops Usyk, hits him with that same uppercut but Usyk doesn't handle it as well and gets wobbly then gets stopped. Is Fury an ATG? He already cleared the HW division prior to Usyk and with a win it would make him even with Usyk who is already an ATG.
I'm really not sure Fury has done ATG things in his career. Beat Wilder 3x but as we all know Wilder can't freaking box. Beat old man Wlad ... well that's OK since even old Wlad was pretty good. But AJ also beat Old Wlad, arguably a better version. Fury ducked the Wlad rematch which did him no favours. Who else has Fury whooped that is a name with weight? Nothing occurs to me. I'll say Fury might be an ATG H2H guy if you take his very best form. But he's been inconsistent in form and has struggled in some fights he should not have struggled in.
If Usyk isn't an ATG then there isn't a single ATG from this era. He's literally the best fighter of the era, p4p.
If Fury wins he should get the reckoning,I'm not saying he's going to win, but what's right is right,that's the bottom line.
