Is Usyk an ATG at Heavyweight?

I'd say so, yes, based on the fact he faced arguably the best two heavyweights of the present era in Fury and Joshua and beat both twice whilst also holding a convincing win over the up and coming Dubois. Prior to Wilder's downfall I would have liked to see Usyk get a win over him too but he's since been exposed and I think that history will show the win over Dubois was the more impressive feat. Ideally, to have a a chance at cracking the prestigious list of top 10 heavyweight ATGs, I'd like to see him get a win over Parker, another win over Dubois and perhaps a third fight against whoever the man of the hour is at that time. All this said, is he an ATG heavyweight? Absolutely but his resume at heavyweight is still a little too thin to crack the top 10 at this time, at-least imo.
