Which heavyweight was truly unbeatable for these years? Sonny Liston 1962-64 George Foreman 1972-74 Mike Tyson 1987-89
Out of the fighters listed I think Tyson overall beat more notable names and I think stylistically he would beat more notable Heavyweights past/present than either of the other 2 Heavyweights. So I'll go with Tyson.
Tyson by far, Tyson would beat both these guys in a single year if they were lined up. Foreman is too primitive, Liston is a slow bully who’d crack under the pressure. MT blitzkreig’d an entire division… Liston chased around guys 20lbs lighter and got the title from a near on Canelo sized guy lol Foreman knocked down a shot Frazier and the best stylistic match up possible in Norton (yawn) Prime (in or around) MT’s scalp collection has more depth then both combined or close to it… let’s see. Tyson has: Ruddock Ruddock (again) Holmes Biggs Tucker Stewart Pinklon Williams Bruno Ferguson Berbick Tillman Marvis Bonecrusher Spinks Tubbs Liston / Foreman has: Frazier Patterson Patterson (again) Norton Lyle Peralta Peralta (again) Machen Williams Williams (again) Folley Roman
