Hector Camacho used to be a hard hitter in first quarter of his career. I noticed by watching many of his videos that he often scores a knockdown but unwilling to really press but would rather circling and jabbing his way to victory. I also think Floyd is pretty hard puncher, definetely not one of hardest but definetely capable of scoring more KOs , but just like the way he negotiate fights, he's only willing when there's less less risk.
I echo Tiger...who despite truly concussive, hurtful power, insisted on fighting conservatively and going for points decisions.
Luisito Espinosa had only a moderate KO % but scored some pretty brutal early knockouts against quality opposition. He took out Khaokor Galaxy in 1, Alejandro Gonzalez in 2 and Kennedy McKinney also in 2. It's just that he could be vulnerable himself but he was a very dangerous hitter.
I think many of the top old-timers from boxing's "Golden Age" (1920s), hit much harder than their very modest KO percentages suggest. Either boxers back then were generally more feather-fisted than today... or (with their busy schedule) they didn't always go all out in an effort to finish their opponents. I believe the latter scenario is the most likely.
Chris Eubank sr .A lot of his fights went.the distance but he could hit hard with one shot .not many could drop Collins and have him in big trouble. Lost something after Watson.
Holmes. He had an underappreciated overhand right that became a definite factor after the Norton fight. In the 90s it got heavier.
Jimmy Young, Chris Byrd, Jimmy Carter, Tommy Farr, Kid Gavilan, Ford Smith, Larry Gains, and plenty of others.
