I recall Tyson commenting on Ruddock's punching power during the post fight interview. He also mentioned years later that Bruno hit him the hardest. What he said about Holyfield was that Evander hit him very often. I recall reading somewhere that Patterson also claimed that Liston hit him the hardest, it's quite possible that the comment was made pre-Liston but I don't remember. As for Ray Leonard, he mentioned Duran surprisingly, even though he made the comment after the fight with Hearns.
