I'm convinced Usyk just wants that AJ payday and Eddie is more than happy to give it to him. Size matters. 3 inches is tiny compared to 7 inches. That being said Usyk is the only 210 pound man who could pose a threat.
Reach Heart & skill is more important as AJ found out. I'm not sure Ruiz would get as lucky as he did with AJ, Usyk is a real pro...ask Big mouth Bellew.
