Even then, thats an experiment and wont take into consideration the adrenaline, fear and confidence you have in the ring to give you that extra bit of edge to push those punches.

Heavyweights will always hit the hardest but if you look at it from a pound for pound status who hit the hardest i would say a toss up of hitman hearns, julian jackson, nazeem hamed (sort off!).

Ali said earnie was the hardest hitter he faced so those words alone put him right up there when you look at who ali faced..
Good post and I think its wrong to always default to the heavyweights. I personally believe that the stronger punchers throughout history are/were much smaller men. Knockouts just look bigger and most people including non boxing fans can usually tell you who the heavyweight champion is.

In addition its the when a punch lands which is what @ElTerribleMorales touched on. Most recently for example the punch that put Manny in a coma. Marquez is not a 0ne punch ko artist and yet that punch delivered in the exact same matter would have most likely stopped anyone in the division and probably a lot of people north of 147. Same with the Marciano shot on Walcott. That punch probably ko's Chuvalo.
