Watching the ali-frazier fights bring a tear to my heart when comparing them to today's heavyweights... Our slow pondering brutes are so lethargic and boring that I can't believe people even watch the division anymore. However, Frazier was very quick, and tireless... he made Hatton and Pacquaio's pressure fighting look tame, and Ali well he had some speed behind those hands... effortless combinations... incredible chin he was chin so cleanly by that left hook so many times I thought his head would fall off. All these fights had ruthless body work, head movement, footwork, fast hands, punches in bunches, heart, and everything else that makes boxing special... For those who haven't watched their fights I suggest you do so. And while you are at it watch Leonard-Duran, Leonard-Hagler, Hearns-Hagler, Duran-Hagler, Ali-Liston I, Ali-Patterson I... I thought the fights were in fast foreward when I first started watching boxing, but their not... They actually use that much foot movement... Incredible.
