There were quite a few good fighters from 169 -195 pounds that did well in the heavyweight division in the 1930's to 1960's before heavies starting getting bigger and in general hitting harder. Fighters like Maxim, Loughran, Greb, Moore, Braddock, etc... There were also next to no skilled big men ( boxers in shape at 220+ pounds back then ) Would they be in the top 5 today at heavyweight?
