Hardest Single Punch you ever saw in a fight

[Jimanuel Boogustus]

The shot that Lewis hit Rahman with sounded like someone driving an axe through a basketball. Love that sound.

Tyson's shots sounded like that too.

Julian Jackson on Herrol Graham.... it was a sickening punch.

The other one I can remember was the shot Dereck Jefferson laid on Maurice Harris- the ko punch. Mouth-piece went flying in the opposite direction of the punch.

It was really sad to see Harris nearly decapitated..

The United States Government

The 'punch' that they landed on Cassius Clay in April 1967.

It put the guy out for nearly 3 1/2 years.

Maybe it was Hatton's chin not being up to it towards the end, but that knockout against Pac was one of the worst things I have seen in boxing. Out cold for minutes. Maybe Martinez against Williams too.
