why cant malignaggi punch?

he just throws his arm at opponents, doesn't put any weight/momentum behind them.

 

hasn't he broken his hand like 9 times

 

If you are not a power puncher from the start then you will not be a power puncher.
All you could do is create angles that would make the most of your punches(even with malignaggi's). Paulie had the speed to do that but not the coach to develop what he has.

 

Cos he's a nancy boy

 

Some people like to apply physics to discussions of punching power. They will often talk about speed. You would think that anyone with speed would be automatically a powerful puncher.
(For those of you who are physics minded, you can read that as acceleration if you prefer)

But speed needs mass to be effective.

If you flick out your hands you will have speed but no mass. If you have proper technique then you will be able to put more mass into the punch, by using your whole body mass in the punch. You sit down on the punch, which makes your whole body connected - if you do this right, then you can also punch quickly - the two are not mutually exclusive.

Put simply - Paulie has speed but he does not put the mass of his body into his punches.

The next thing is where are you punching? You can learn pretty quickly with a good instructor (and I mean in under an hour of practice) how much difference it makes on where you punch.
If you punch someone's face, and you are thinking of their face and aiming at their face, then you may sting them.
If you punch somebodies face, and you are thinking through their skull and aiming through thier skull, then you may devastate them.

Paulie doesn't do this either.

 

some people just can't punch as hard as others, that's why they say punchers are born. even if malignaggi put everything into a punch, he still most likely wouldn't punch hard, while you got guys who technically punch all wrong, and still knock people out. that's just the way it is.

 

:fight

 

i not saying thats the only reason but it can't help,

 

What you were taught is exactly correct, but only half of the story. The other half is how it is delivered.

As to whether Paulie can learn? That's a tough one. If he was caught early in his career then it would be worth a shot.
Right now he has a bunch of muscle memory to overcome, that doesn't get easier the older you get. He could end up becoming totally ineffective by playing with fundamentals of his style right now. It's right back to the drawing board.

 

Accelleration isn't the key, it's kinetic energy.

KE = 1/2 x mass x velocity squared.

If you increase the speed, the Kinetic Energy increases by a factor of the new velocity; if we set the mass as an arbitrary "1" and use a velocity of "2" (m/s), then the KE is 2J. But if you DOUBLE the speed, you get a KE of 8J, which has increased by a factor of 4.

 

it doesn't matter. even if malignaggi punched 100% correct, it would only increase the power slightly by tecnhique. why do you think all the top trainers say punchers are born, not made? it's for a reason. not everybody can punch hard.

 

If his technique was 100% correct then he would punch much harder.

But it is rare to find anyone who can get their technique that good. Maybe that is the "born puncher" aspect.
