I wouldn't leave Dempsey out of this equation. And between 1912 and 1924, Carpentier scattered a trail of bodies behind him. (People sometimes forget that he started his career at 14.) Ike Williams is an excellent mention.
Greb had power. He has a low knockout rate, because he was mostly a middlweight fighting heavyweights. He was always chaseing after bigger fish.
Duran - much quicker at lightweight than he's given credit for. Holyfield - at cruiserweight and as a young heavyweight, blistering combinations and very good power. Wilfredo Gomez - yikes. Scary good until Sanchez made him look human.
To name a rather unknown fighter, Charlie Weir, who was a welterweight / jnr. middleweight who caused a commotion here in the late 70s / early 80's with some awesome knockouts. He had a great blend of speed and power, but unfortunatley no chin and no defence. He fought Davey Moore but was KO'd in 5.
There's a blast from the past. Gary Guiden was another very very big hitter Moore beat just after. Great stoppage records those two.
For a brief period of time, in the mid to late seventies, when he was the ruler of the super bantamweight division, and racking up around 20 defenses, Wilfredo Gomez was as close to perfection as you could get. Just watch a tape of his fight with Carlos Zarate and see what I mean. Zarate was perhaps one of the most feared, dangerous and lethal fighters in the world, p4p, and look at what Gomez did to him. When I first saw that fight I was so impressed. Gomez sort of fell apart when he met Sal Sanchez, and was never as good afterwards, but he was , up until then, an almost unreal blend of power, speed, craftiness, and cold blooded killer.
Good post, Gomez was thought at one time to be just about the greatest fighter on earth. His winning and ko record pre Sanchez is awesome, and it's a shame later on he let his surprising brilliant defensive and countering skills wilt, instead moving toward a regime based more power and less on boxing skill.
Lennox Lewis, at times he could resemble a 245lb Tommy Hearns. Perhaps not that surprising when both had the same trainer, both had a great jab (although Lewis's cant compare to Tommy's) and both had a great straight right hand. Lewis was slower of course but then he was a lot heavier.
Joe Gans he always seemed to be very quick and had great power, Ezzard chalres is another one at 175 he even knocked a fair amount of heavyweights.
His power at 147 was very good. Aaron Pryor had a good blend of power and speed. Roy Jones Jr at middlweight/super middleweight.
