Single best power punch ever...

[NAB]

Any Julian Jackson power punch!!!

[cple]

Joe Louis' right hand was pretty much perfect.

[dodge]

Any Jack Dempsey punch.

[Boxer2005]

Tyson...right uppercut

[ejk22]

One specific right hand that rocks the house is Maskaev's on Rahman, man I get so much enjoyment out of watching the replay on that. Then his lowlife fans start rioting in the stands and throwing chairs because they are ****ing jerk-offs!!

[Xecutioner]

hearns shouldve been arrested for what he did to duran. imo that win sealed hearns as possibly the greatest offensive fighter ever. no one before or afterwards ever came close to doing that to duran, not leonard, hagler, barkley etc etc. the second knockdown hearns hit him with a right to the body that made him pop up in the air. i had to see that shizzle in slow motion to actually see the punch land it was so damn quick. and of course the sledge hammer that bent him in half.

[Piggu]

Tommy Hearns's straight right hand.

And Micky Wards left hook to the body.

Of all time? It's hard to say. The most effective weapon and hardest punch are not necessarily the same thing. I like to believe that the 2 hardest heavyweight left hooks of all time belonged to Joe Frazier and Floyd Patterson, but neither was really a one punch knockout artist. Tommy Hearns' right hand,Tua's left hook, Shavers' right hand, Tyson's uppercut, and Tito's left hook were all memorable trade mark shots, but to pick one is very difficult.

Tyson had the same ****ing power in any punch. Left hook, right cross, left or right uppercuts. Therefor i pick him.
