Hardest Single Punch you ever saw in a fight

[Jimanuel Boogustus]

5) Lennox first big right in Ruddock.

my man!!

What a punch that was. Made Ruddock's legs do some kinetic energy transference type....

BASICALLY TURNED HIM INTO A NEWTON'S CRADLE

Rocky Marciano's Suzy Q on Walcott "THE PUNCH"
Tommy Hearns' laser right cross on Roberto Duran
Earnie Shavers' explosive right on Larry Holmes I'm amazed Larry got up

Deontay Wilders left hook on Malik Scott.
A jab Paulie Malignaggi landed once, can't remember which fight but it was for sure the second hardest punch I've ever seen.
