Pound for pound and it welterweight??s Pound for pound, definitely jmm,he also has a higher ko percent. At welter, i still think jmm hits harder.maybe its cause floyd is too focused on defense, that he doesnt commit on his punches,but his punches sting,are annoying moreso than lethal power punches. Jmm loads up more on his punches, they seem to have more power and he is definitely trying to ko his foes. I also dont believe floyd could ko or let alone kd pac like jmm did. Floyd has one legit ko at welter against hatton. I also think jmm could stop cotto
Marquez I would say but Mayweather doesn't push for knockouts when it's obvious he could. Marquez goes for the finish.
Floyd could KO Pac. It's not neccessarily the power behind the shot that results in the KO. Timing and accuracy play a big part. Floyd catching Pac rushing in could create a KO IF Floyd held his ground. That said, JMM sits down on his punches more often, so he throws harder shots with more frequency.
