He beats everyone you listed, Wright being the most difficult. Wright, along with Hearns, would provide his sternest test among any JMW's, aside from WW's moving up like Robinson, Leonard, Griffith, etc.
He beats every single one of them. The toughest opponent on the list for him would be Wright, but he'd still have beaten Winky by clear decision. Everyone else on that list he beats the **** out of, esp Verno Philips. Idk why you even listed that journeyman. Only 154 pounder in history who could have possibly beaten McCallum is Hearns.
RJJ was at 154 for a couple of fights VERY early in his career, and if he had more seasoning during his brief stay there, he probably could've beaten McCallum at 154.
That means nothing. Roy was not a junior middleweight. Roy's natural and best weight was 168. He coulda never stayed at 154 long, he'd be beyond weight drained.
That was hypothetical, staying there for long would've been dumb. He was only there for two fights, anyway.
