Graham was not a big middleweight at all in his prime, he could’ve easily kept making 154lbs as he did early on in his career
Graham probably dominates until late on & gets stopped. He had good defensive skills, if a little unusual. He probably drops his hands at the wrong time & gets nailed. Not for the first time !
Graham fought at 154 maybe the OP thinks Graham would have stood a better chance v Charlo at 154 than 160 because Graham was stopped twice above 154.
Given Jernell was the one outboxed by Tony Harrison, you'd have to give this to Graham, no matter how chinny. Jermell's KOs come when he is moving forward reigning damage in his opponents, I don't see him getting into this position against Herrol.
Most people had Jermell beating Harrison in the first fight. And Jermell won the rematch. Graham never avenged a defeat.
Harrison boxed Charlo`s ears off as McCallum would have at 160 despite struggling v Graham at that weight.
