Kind of, yeah. You could add Langford and Greb, too...as they competed successfully at LH. But, even in historical times, it was clear that you had to be pretty exceptional to do so at world level.
Harry Greb wasn't the World Champ at LHW (not given the chance) but he still dominated bigger men at 175. He was 5'7. Mickey Walker was also successful at these weights (natural ATG Welter / Middle). He was 5'5 / 5'6.
