Not sure? Thankfully never been hit by either guy! The both seem to pack a punch to the point that we are probably splitting hairs. I might reluctantly say Lopez but I imagine it is close
It's close but the difference is the speed that Pac had. That speed combined with his power was truly something to behold. Still is.
I think that Danny Little Red Lopez hit much harder than Naseem Hamed. Naseem was much quicker, could strike at different angles like Lomachenko. But Danny's power was mind numbing, did put many to sleep when he landed his very potent right hand, Juan Malvarez comes to mind. I think it was because Lopez set his balance to throw the right hand, set up by the left jab.
Not much in it I'd say, assuming we're talking about Naz setting his feet and putting maximum torque on his shots - although he rarely did that, so in actual practice probably Danny.
Arguably the two hardest hitting featherweights ever. I'd probably give the edge to Lopez, but I can see arguments either way. Naz was more explosive, but Danny's power was effortless.
