There must be a heap of old time fighters who beat a lot of those guys come to think. It has Armstrong and Robinson on the list, but everyone else has fought in the last twenty years or so.

Sam Langford and Bob Fitzsimmons are two I could think of as well, but who knows what those guys actually weighed is another point perhaps? I imagine a lot of early HW challengers would have scaled in way way under 200 pounds.
