Sam Langford pretty much beats every LHW ever. A lot like Mickey Walker- his physical abilities for his weight class and his actual skills alongside it, makes a fighter feel like they’re to resist a tsunami with a beaver built dam. Different breed. No man smaller then those guys wins in there prime. Guys who fought Sam and Walker at there weight had the same advantages a zebra has over a lion…
Based on reputation I’ll go with Langford though I confess I haven’t seen much of him. Bivens was both tough and tricky however and beat a lot of hall of famers. This might be a close fight
