I think Tyson had great power but IMO Louis was the greatest puncher of all time.
I think Tyson is in at least the top 15 of all time but doesn't crack the top 10 for me. In the top 10 hitters for heavyweights though.
I mean you guys like Langford, Moore, Wild, Saddler, Ketchel, Fitzsimmons, Foreman, Shavers, Oliveras, Gomez, Dempsey, Marciano & Liston who could all rate higher!
