Robinson would have owned if there was a junior middleweight division in his era. He was a big welterweight, but a bit too small to be as successful at 160. Who wins between the GOAT and the Body Snatcher?
Very difficult to say of course. Robinson looped a little bit with his punches and didn't have the Leonard/Hearns speed, but considering his punching power and chin I'd make him the slight favorite
Robinson vía decisión. McCallum is crafty and likely avoids a stoppage but Robinson’s speed, movement, and work rate carry the day.
