Carrying your power through the weights, why not always?

[Controversial]

I've been thinking about how some big punchers keep their power when they moved through the weight divisions, for example Hearns and Pacquiao, yet other big punchers have moved up in weight and their punch doesn't have the same impact anymore, for example Roy Jones and similarly Benn. Is it a case of the opponents got better (or worse)?

What do you reckon?

Wow no takers? Thought it was an interesting discussion.

Nobody's punch has the same impact. For some it just diminishes far less than for others.

I guess there's force, accuracy, timing... Hearns had an accurate punch that he could land unexpectedly. That didn't change as he went up the divisions...

I was about to say that Hearns didn't carry all his power to the higher divisions but then remembered Dennis Andries bouncing all over the canvas at 175

Tall sinewy punchers seem to carry their power with them more than short stocky types

Generally speaking punchers are at the biggest disadvantage when they move up the divisions.
