Weight helps but its far from most immportant thing, just look how Tommy Hearns looked and what he weighted but he punched harder than half of SMW or even LHW fighters...
It's about transferring energy throughout your body in a sequential, timed movement. There are a lot of factors involved including strength and weight. The heavier the boxer the more force is transferred to a target, that's been proven in scientific studies. There will be exceptions of course but in general that's how it works and that's why there are weight divisions.
Golovkin hits so hard based on..... What? Stopping a shot Ouma in 10 rounds? Some club fighter Cruiserweight now a Light Heavy said he punches hard?
I used to be a golf pro for 5 years and technique is the key to power transition , however if you have the correct technique and add muscle then you will hit the ball further , but also more consistantly . I think this is the same with boxing.
Proska has fought one decent opponent and he got an early corner stoppage. The overrating of Golovkin is ******ed but tosay Proska has the power advantage is even more ******ed.
Generally when the weight of the opponents go up, your KO ratio goes down. Ali had a 35% KO ratio on 215 lbs opponents, frazier 45%. Also Holmes was generally a bum beater. KO ratio of his opponents was a median 25%. the boxers with the best real heavyweight record (2x200lbs) he faced were: Chuck Wepner. 22-10 Cleveland Williams 29-9 Gerhard Zech 18-6 Mike Dejohn 14-4 Nino Valdes 16-5 (Ali was a cruiser in the 60s, what is widely considered his prime he had a median 199lbs weight)
There is a big difference, between punching heavy, and punching sharp. Cotto vs Pacquaio was a good example. It appeared that Pacquaio hit harder. Cotto punched heavier, (thud, thud) Pacquaio punched sharper. (Crack, crack)
Speed and power. Valuev probably hit with much power, but he was so slow that he had trouble to accelerate your head fast enough. Compare it to a freight train going 2 mph and a punch from Pacman. The train hits you with much more power, but only Pacman could knock you out. Valuev also had other troubles that come with gigantism.
All other things being equal, the heavier mguy hits harder because hes putting more weight behind his punch. So basically unless the lighter guy has way better form and technique, the heavier guy will hit harder. Its basic physics
The optimum weight for big punchers in the heavyweight division is 225-235lbs. Very few fighters are physically able to have all the attributes of a puncher beyond that weight. Of all the super heavyweights in history, only two have been serious punchers, that is Lewis and to a lesser degree, Wlad. Beyond a certain weight, most guys are too slow and cumbersome to be 'powerful'.
Ali's prime wasn't the whole decade of the 60s. His prime was from '64 onwards and he was never under 200lbs during that period.
This is true, however, it's very rarely the case that other things are equal. How many 250lb or more heavyweights actually have good footwork and technique? How many are fast punchers? Weight and strength is one thing but unless it's combined with technique and speed, it doesn't mean power.
