Putting aside me thinking the fighters nowadays would beat the guys 60 or 70 years ago I think that Ezzard Charles and Billy Conn should be farther up the list, and I wouldn't put Henry Armstrong ahead of Willie Pep. Also I would put Gene Tunney a lot higher along with Tony Canzoneri and Joe Frazier. I don't see how they place Marciano ahead of Joe Frazier... Or Archie Moore ahead of Ezzard as good as he was. I also think Sonny Liston should be up there somewhere.
