Rocky was around 184lbs (Possibly started even lighter). I’ve no doubt he could make 167lbs in the modern era. Floyd fought at Light middleweight so they weren’t so different sized a fight couldn’t happen. Marciano was 2inches taller but gas be up 4inches in reach. I don’t think Rocky was really any bigger than Canelo for example. Rocky would punch harder than any previous Mayweather opponent but relied on holding and hitting and threw wild telegraphed punches which I can’t see landing. Who you all got at 167lbs?
