Mustafa Hamsho Tony Sibson Wilford Scypion Alan Minter Juan Domingo Roldan Caveman Lee Prime Robinson comes in the ring as a welter within the 147 limit. The above men are fighting as middle weights.
Welterweight Robinson fought a lot of middleweights. His record against middleweights between 1942 and 1950 was 54-1-2. Although wasn't inside 147 for all of those he was usually giving up weight. His only loss at middleweight in his prime 1940s years was against Jake LaMotta which he avenged several times. I think he'd win all of these but he wouldn't stop them all. I can see Hamsho, Sibson and Roldan losing competitive but clear points decisions. I think he'd stop Scypion, Minter and Lee.
