Ali and Frazier, two of the GREATEST ever, power, finesse, courage, brutality, lethal .... all describe these incredible athletes.
Styles make fights though.... Foreman literally wrecks Frazier and Ali puts him down, ( although no re-match ever offered
) Norton arguably beats Ali 2/3
Ali had the heart of 2 lions and a jaw of granite .... def top 3 all time heavyweight
Frazier I think is underrated as an all time heavyweight, gotta be top 7 or 8
