Usyk's record PALES into insignificance against Frank Bruno's record because Frank defeated Oliver McCall. Ergo Bruno>>McCall>>>>>>Usyk.
You know, I really like Usyk. In a year or two, might surpass McCall. But back in the day, Loved the Atomic Bull!
McCall actually DOES have a much deeper heavyweight resume than Usyk, who has only three fights at the weight. And I thought Chisora edged him. McCall won and lost against the best. Usyk still has a lot to prove at heavyweight.
