Will you tell me, that without his godgiven talents (speed, skills, precision) he would have scored so many KO´s as a MW? Don´t forget, I asked for rare power, not for an overall puncher...
I agree with you position on Jones here. He must make the top 5 of overall punchers at 168, but as far as pure power goes at Middlweight, he's just very good.
Considering Jones carried his power all the way up to 175 I can only imagine that at 160 he harnessed more raw power for that weight. Jones was an example of a puncher who fought like a boxer. I think he could crack more than you give him credit for.
If you can 'teach' Motor City Cobra's power, Manny has been dropping the ball for the last 25 years...
Compare that to George Foreman's lot of raw power, but lacking KO artist abilities. Out of 30+ fights I've seen he scored only a couple of one-punch KO's at best. Without skills and timing, it's useless.
James Toney had very good power at middleweight, but not great power in the league of McClellan, Ketchel, Fernandez, Jackson, etc. Marvin Hagler was a very hard puncher who did damage with every shot. But he was more of an accumulation puncher. I'd put Hagler in the honorable mentions though
Very surprised nobody has mentioned Hurricane Carter yet. After all, the chap took out Griffith inside a round. The Toy Bulldog might also merit some consideration.
