One punch knockout vs heavy handed

Was wondering why some punchers like Pacman can knockout a fighter with one punch and others like Cotto punishes people with accumulation of punches but cant knock them out with one punch. How can you explain it? The muscles used while throwing the punch? The angle of the punches? What is the physics involved in this differnce of punching power? At these higher weights, Pacquiao is an accumulation puncher. A one punch knockout artist needs to be quick. The punch that knocks you out is the punch you don't see. Tommy Hearns, the baddest one punch knockout artist I've ever seen, used to hide his right hand behind a sneaky, sledgehammer jab. You didn't see the right hand coming and it made you disappear. For the most part, Cotto and Pacquiao throw longer punches than say, Ray Robinson who blew guys away with 6 inch hooks you didn't see coming.

Well said mayne. Toneys KO's of Jason Robinson and Charles Williams definitely support that. I suppose Trinidad didn't lay you flat out like Hearns and Jackson did, but he took you to the edge of that territory. I love those KOs by Toney. Also, Toney's KO of Michael Nunn. Nunn may have gotten up, but he was as good as done after taking that left hook. I think with Trinidad, as you said, it was just one shot that put you in the territory, and he'd follow up and finish a guy. Or in the case with Reid and Vargas, one shot turned the fight in his momentum. Reid was doing well, but after that one left hook in round 7, it was all Tito. Vargas was doing well in rounds 4 and 5, and even 6, but when Tito landed that right hand late in round 6 and Vargas started holding on, Tito took over the momentum again. I'd add Foreman into the "heavy-handed" category and not the one-punch KO artist. His most famous "one-punch" KO, over Moorer, I'd hesitate to even call a one-punch KO. Moorer said he was already hurt and out of it from the first one-two, not the finisher.

I agree, except I put Tito somewhere in the middle. He could do a lot of damage with one punch and change the momentum of the fight, but the only time I remember him stopping a guy with one shot was Pendelton, to the body. Pineda, I guess, also to the body, but I think he was hurt to begin with and just said "forget it" when he took that brutal body shot. I would also add timing and angles to the 1 shot KO quality. Catch a guy at the right time when he doesn't see it coming. James Toney ain't a devastating heavy-handed puncher, but he's stopped guys with one shot. Well said mayne.

Pacquiao is more of an accumulation puncher like Cotto. An example of a guy with one punch knockout power would be Tommy Hearns, Julian Jackson, Felix Trinidad or Kostya Tszyu. A lot of one punch knock out power deals with technique and speed. If you look at a guy like Arguello or Joe Louis, they threw every punch with perfect technique. They got great leverage on their punches and they'd fire them in a quick, compact fashion. They would also shift their body weight accordingly as they would punch through their target. That's a fairly crude answer, but it covers the basics. Of course natural muscle mass, bone density, and other aspects of physics have something to do with it.

Me2007 has it. Also add in the angle of the blow and whether they saw it coming.

timing + hand speed + weight transference + luck = one punch knockout

The word explosiveness summarizes your argument.
