It doesn`t matter, the nearest thing was Tua but nobody Tyson`s size would have had the same impact he had if they had fought in his era, he beat some guys that were in the 6`3-6`5 range, awesome.
Name me fighters that beat other fighters that had a 7 inch reach advantage and had the speed of Fury, who also out-weighed Usyk by a significant amount.
So a guy with a ridiculously small reach for the division overcome (obliterated in most cases) multiple guys way taller than himself with huge reaches. Sounds like reach sure isn't the be all and end all.
It's the open division. Reach advantages and disparities are going to be routinely bigger due to that. The weight difference also rules out lower divisions. If it was so much a miracle the odds makers would not have had things remotely close to even money. End point - Usyk beating Fury is very impressive but nothing that was unexpected for about half the population.
