Foreman/Lyle - best action HW fight ever Louis/Schmeling II - the 2nd "Fight of the Century," global/political/historical relevance, best KO1 in HW history Frazier/Ali I - the 3rd "Fight of the Century" Ali/Frazier III - war Dempsey/Firpo - one of the most iconic snapshot moments in boxing Johnson/Jeffries - the 1st "Fight of the Century," then biggest promotion and most anticipated fight ever Lewis/Klitschko - best fight close to era, great battle, controversy, and much blood Douglas/Tyson - an upset of all time and a good fight in itself Bowe/Holyfield I - great battle of era's all action fighters Tunney/Dempsey II - "The Long Count" dramatic ending I think this list captures almost all of the ATG HW's across all of the era's, with most of the dramatic and legendary fights and tales.
