No, probably top 30-50
Great fighter, but not enough wins and not enough great wins
His cruiser run was immense, but these lumps at heavy are not great and they are all from one country. The brits have never had so many top fighters and chisora still being top 10 years past his best says everything
I suspect Usyk has the talent to be top 10 ir so and doing this at 38 is amazing, but he just doesn't have enough wins on his resume and a zero isn't everything, especially when you fight once per year against the same guys
