Who Wins: Mike Tyson vs. Joe Frazier
both fighters pretty much had similar styles and similar physiques, this match up i think would qualify as fight of the century. tyson is more heavily muscled but frazier had a slightly longer reach. both fighters are known to bob and weave, were exceptional pressure fighters who can unleash a ferocious left hook.
frazier had one heck of an iron chin, foreman had to knock him down 6 times before he was counted out but tyson in his prime had the best combination of speed and power, his work rate was phenomenal. however, frazier had superior mental composition than tyson and unlike many of tyson's opponents, will not wilt under pressure. i believe frazier wins this via ko in the late rounds.
