Team 1900–1949 (Old School Killers with Modern Training) Jack Johnson Jack Dempsey Gene Tunney Joe Louis Rocky Marciano Sam Langford Harry Greb Archie Moore Team 1950–1980 (Golden Era Technicians & Punchers) Muhammad Ali Joe Frazier George Foreman Sonny Liston Larry Holmes Michael Spinks Bob Foster Ezzard Charles Tournament Bracket Quarterfinals 1. Joe Louis vs Michael Spinks Louis’ fundamentals + modern strength = too compact and sharp. Louis by TKO 9. 2. Muhammad Ali vs Harry Greb Greb’s chaos vs Ali’s length. Modern Ali too big, too fast. Ali UD 12. 3. Jack Dempsey vs George Foreman Violence. But modern Foreman’s size & jab overwhelms. Foreman TKO 6. 4. Rocky Marciano vs Larry Holmes Holmes’ jab is a nightmare for Rocky. Holmes UD 12. 5. Archie Moore vs Joe Frazier Moore’s traps vs Frazier’s body attack. Frazier breaks him down late. Frazier TKO 10. 6. Gene Tunney vs Sonny Liston Tunney too small physically here. Liston KO 7. 7. Jack Johnson vs Bob Foster Johnson’s size + clinch control neutralizes Foster. Johnson UD 12. 8. Sam Langford vs Ezzard Charles This is elite chess. Langford with modern conditioning is terrifying. Langford SD 12. Semifinals Joe Louis vs Muhammad Ali Prime + modern science Louis is sharper defensively than people remember. But Ali’s size & movement probably wins a close one. Ali SD 12. George Foreman vs Larry Holmes Holmes has the jab to survive… but young Foreman’s pressure is brutal. Foreman TKO 11. Joe Frazier vs Sonny Liston Liston’s jab disrupts Joe early. Joe makes it ugly but eats too much. Liston TKO 8. Jack Johnson vs Sam Langford Langford’s power + modern explosiveness breaks through. Langford KO 10. Final Four Muhammad Ali vs George Foreman With modern nutrition & recovery, Foreman is even more dangerous. But Ali’s ring IQ still solves him. Ali UD 12.

Championship Muhammad Ali vs Sonny Liston (Modern Versions) This time: Both with modern strength training 12 rounds No mystery injuries Ali’s foot speed + length + chin probably carries him again. Winner: Muhammad Ali (UD 12)
