Yeah I know about the Emile fights and the age disparity but I was more getting at Griff muscling Tiger after re-watching it the answer for me is "Sometimes" lol
Well, Harold Johnson was certainly a bit heavier, as was Archie Moore in the 50s and early 60s, but I can't think of any other 60s LHWs that were heavier than Torres. Neither Hank nor Foster were heavier. Maybe Frank DePaula?
