As I mentioned yesterday, Muhammad was simply to big, strong, tall and quick for Jerry Quarry. Muhammad was 6’2 or 6’3, 215 pounds or so of solid muscle, speed and intelligence. Speed in his hands and feet and you combine that with his strength, his ability to both take a good punch and deliver several great punches in a few seconds, plus his accuracy, he was simply too much for Jerry Quarry. Who was 5’10 or 5’11, under 200 pounds. For Quarry to make this a good fight, he simply had to get inside of Muhammad and pound on him.
The problem being that the only short heavyweight boxer to have any success at that, was Joe Frazier who was bigger and stronger than Quarry and could take more punishment and still move in on you and pound your body. Quarry left both of the Ali fights a bloody mess, because he took so much punishment in both fights before he was able to deliver any punishment. The two Quarry fights were a tune up to fight for Ali to fight Joe Frazier for the first time in 1971 and the second time in 1973.
