Mr. Ali perfectly timed the overhand right. From this overlooked and extremely underrated camera angle, you can see that Mr. Ali was able to put his full body weight into the punch. The overrated Phantom Punch, from the other camera angle, does not show how Mr. Ali was able to use his body to leverage the Anchor Punch unhindered.
A punch does not start and end with the fist but starts from the ground. The body of a fighter that begins to throw a punch is like the Handle, Thong, and Fall of a whip, and the fist, when making contact with its target, acts like a whips Popper. Remember that this fight occurred before the famed Bruce Lee could marvel the world with his “One-inch punch.”
It was not the punch that brought Sonny to the canvas, but the “sweet science.” Mr. Ali was ahead of his time. “TWO MOVING OBJECTS, BOTH POSSESSING MOMENTUM BY VIRTUE OF THEIR MASS AND VELOCITY, COLLIDE WITH ONE ANOTHER. WITHIN THE SYSTEM CREATED BY THEIR COLLISION, THERE IS TOTAL MOMENTUM MV THAT IS EQUAL TO THEIR COMBINED MASS AND THE VECTOR SUM OF THEIR VELOCITY.”-science clarified.com
