However, we can not leave the Ali victory from the equation. It is a better victory than Dempsey had and it is that by quite a distance. Please do not compare an old, out of service Willard to a close to prime Ali. And to say Jack came close to Tunney does no real service (is Tunney even a Top 20 head to head heavy?) if we can conversely say that Frazier came close (some think more than close) to beating Ali the second and third times around. You say that Foster never beat a good heavy. However, I only included him because you can't make a list of Dempsey's top 5 victories without including Gibbons, who was also a lightheavy and who also didn't do anything at heavyweight. I do not favor Sharkey over Ellis or Quarry or even Bonavena. But fine, if Sharkey is the best of Dempsey's victims, here we have Dempsey's list: Sharkey, Willard, Fulton, Gibbons, Miske. And here we have Frazier's: Ali, Ellis, Quarry, Bonavena, Bugner. Head to head, I am taking the latter by country mile.
