In the 60s and early 70s Ali was arguably the greatest heavy weight ever...excellent hand and foot speed, good power, and could go 15 rounds standing on his head. But when he started the rope-a-dope garbage, that was the beginning of the end...he fought long past his prime and was awarded many decisions later in his career that should've gone to his opponents (I personally thought he lost all 3 Norton fights, but was given the decision in two of them). Any way, he was certainly one of the greatest ever and boxing and it's fans have suffered a huge loss...
