Sullivan’s star waned somewhat as the people who had seen him fight started to die. Jeffries would later suffer the same fate. It is striking that a lot of people who saw Jeffries fight early in his career, compared him unfavourably to Sullivan as a puncher and a finisher. I am not a big fan of the "weak era argument", but I think this is one case where it can be justified. I would feel very comfortable in saying that Paddy Ryan and Joe Goss were weaker than the best contenders of both he previous era and the subsequent era.
