One of Ali's greatest tricks was to make opponents over commit by pulling straight backward from punches. Disciplined, world-class boxers chased Ali and threw themselves off balance attempting to hit him because he seemed to be an open target, only missing and leaving themselves exposed to Ali's counter punches, usually a chopping right.[99] Slow motion replays show that this was precisely the way Sonny Liston was hit and apparently knocked out by Ali in their second fight.[100] Ali often flaunted his movement and dancing with the "Ali Shuffle," a sort of center ring jig.[101] Ali's early style was so unusual that he was initially discounted because he reminded boxing writers of a lightweight, and it was assumed he would be vulnerable to big hitters like Sonny Liston.
Ali probably had the fastest hand and foot speed ever seen in a big fighter. Using a synchronizer, Jimmy Jacobs, who co-managed Mike Tyson, measured young Ali's punching speed versus Sugar Ray Robinson, a welter/middleweight, often considered the best pound-for-pound fighter in history. Ali was 25% faster than Robinson, even though Ali was 45–50 pounds heavier.
"No matter what his opponents heard about him, they didn't realize how fast he was until they got in the ring with him," Jacobs said.
The effect of Ali's punches was cumulative. "Ali would rub you out," said Floyd Patterson. "He would hit you 14,000 times and he wouldn't knock you out, he rubbed you out."
Charlie Powell, who fought Ali early in Ali's career and was knocked out in the third round, said: "When he first hit me I said to myself, 'I can take two of these to get one in myself.' But in a little while I found myself getting dizzier and dizzier every time he hit me. He throws punches so easily that you don't realize how much they hurt you until it's too late."[103]
Commenting on fighting Ali in his prime, George Chuvalo said: "He was just so damn fast. When he was young, he moved his legs and hands at the same time. He threw his punches when he was in motion. He'd be out of punching range, and as he moved into range he'd already begun to throw the punch. So if you waited until he got into range to punch back, he beat you every time."[46]
Floyd Patterson said, "It's very hard to hit a moving target, and (Ali) moved all the time, with such grace, three minutes of every round for fifteen rounds. He never stopped. It was extraordinary.
