Hardest heavyweight punch of all time to score a k'o or knock down

[Jimmy The Gent]

Our E'nry could really dig mind, Ali did go on to destroy though!

with a brown patch in his pants though

[slicksouthpaw16]

I think it was when marcianno hit jersey joe walcott when they threw punches at the same time but marciannos landed first. that was the hardest knockout punch i ever seen. he put him to sleep with that one.

So many great punches, it's hard to pick.
Marciano - Walcott,Walcott - Charles,Louis - Schmelling,Lewis - Rahman and Tyson - Berbick are some of the best though

when David Tua hit John Ruiz and put him to sleep in like what..19 seconds? you could hear the solid thuds as Ruiz slumped to the canvas

[ForemanCrossArm]

Foreman - Frazier.
Tyson - Spinks.
I think Tyson's upper against Buster was amazingly strong (especially for that late in the fight, but it shows you how much Buster wanted to win that fight by getting up).

[Verstyle]

One of the hardest and underrated knockdowns Ive ever seen. You can even hear the thud of the shot. Even on the reply(which they showed plenty of angles on it on) They show where Mike gets all that power from.How he pivots and turns the hips.

Ray Mercer vs Tommy Morrison (hit gets hit like a heavy bag while hes out cold)
David Tua vs John Ruiz (you can hear the impact...)

@ vertasile, thats one crazy hit

[ForemanCrossArm]

can we get a "scariest combo" because that would HAVE to be Gooney (almost) killing an aged Ken Norton in the corner.. damn, that was brutal, ugly, etc.

Ray Mercer vs Tommy Morrison (hit gets hit like a heavy bag while hes out cold)
David Tua vs John Ruiz (you can hear the impact...)

@ vertasile, thats one crazy hit

Yeah it was.The sound of the hit was crazy.
