Think about it, Robinson and Charles are identical style wise, very good balance, not slick, but still very good footwork, loose left hand pawing and light jabs to set up rights and set up combinations, were great with that whipping left hook as a lead or on the way out also, could counter well, and Jones and Walcott are very similar also, level changes to set up lead rights, feints to set up leaping lead left hook, would do unorthodox stuff like casually walking into a more square on position or even a slight southpaw stance and then throwing the fast lead right side it’s closer. Also Jones is bigger than Robinson as Walcott was bigger than Charles and both pairs were very similar height wise. With that being said, who gets the better of a 4 fight series?
I lean towards Jones since he's the bigger man and harder puncher. Robinson grew into a middleweight at 30 years old. Jones was a light heavyweight with day before weigh ins, so he was 180-185 pounds on fight night. Which means....Jones likely would have fought at both light heavyweight and heavyweight had he been around in Robinsons time. Just like Charles and Moore, he probably would have turned pro at middleweight and then moved up to light heavyweight and heavyweight. Had Jones been around in 1952, he likely would have been a challenger to Maxim at light heavyweight or even Marciano at heavyweight rather than a challenger to Robinson at middleweight
Jones was probably a good 20-25 pounds heavier than Robinson in real terms. They were about the same height and Robinson was a great puncher but he’d effectively be going up against a guy who was a light heavyweight by the time they stepped in the ring - and we don’t know what impact Robinson’s punches would have on someone that size. I’m sure he could still hurt people and in hindsight, Jones probably never had a great chin but with him it’s all the other gifts he possesses that means that Robinson’s power might get neutralised. Jones was preternaturally gifted in terms of his reflexes and his combination of speed and power. Of course, Robinson was insanely talented, fast too and more fundamentally sound (although still capable of the kind of unorthodoxy supernatural talents possess) and we know he had a great chin plus great resilience as well - he was a greater all-round fighter than Jones. However, I think Jones’ physical advantages would probably be just too much for Robinson.
IMO, RJ was still a work-in-progress @160. His win over Hopkins looks impressive in retrospect, but Hopkins was in the same formative stage of his career as Roy, & both fighters looked tentative & overall unimpressive vs. each other IMO. @ best, I think Roy only just began to reach his peak in his final fight @the weight, vs. Thomas Tate. I'll take a candidate for GOAT MW over the 160 version of RJ.
