In this article Jack Johnson rates the top 12 all time heavyweights up until April1929. 1.Bob Fitzsimmons 2.Jim Jeffries 3.Peter Jackson 4.Jim Corbett 5.Sam Langford 6.Sam Mcvey 7.Joe Jeannette 8.John L Sullivan 9.Jack O Brien 10.Tom Sharkey 11.Gene Tunney 12.Jack Dempsey Johnson's placing of the more modern boys like Dempsey and Tunney are certainly contentious,as is the fact that he includes O Brien but not Burns who was clearly better than O Brien. Johnson gives fulsome praise to Fitz and Langford, but doesn't think much of Sullivan whom he admits he never saw. http://news.google.com/newspapers?id=mmpjAAAAIBAJ&sjid=G3kNAAAAIBAJ&pg=1614,6246626
