Can only speak for Willie Pep, who I knew well 'n trained with. He'da sold his left nut for an eraser.
For that particular motivation, we typically have to first look at those who experienced the trauma of having a ring fatality at the end of their fists. Griffith did not really have the temperament to go for broke even before Paret III. He had around 80 fights in 15 years after Paret, and stopped only ten, mostly second raters, almost by accident. But Paret I in 1961 was a superb clean knockout, and Griff later became the first to deck Tiger in 1966. At no time was his power ever questioned. Charles produced fine stoppages after Baroudi, but witnesses to his career before and after leave no doubt that he was never the same. Mike Gibbons slammed brother Tommy for falling in love with his power. Mike himself was one of the few to hold a knockout win over McGoorty. There are reports that he preferred not to hurt his opponents, out crafting them instead. Walker openly admitted carrying opponents, though he vehemently denied ever throwing a fight. On one occasion, he was fighting a friend of Al Capone's. (Sailor Friedman, I believe.) Capone told him, "Mickey, the Sailor is a friend of mine. Don't hurt him. (Walker made it clear that this was a plea, not a threat.) He did carry Capone's friend, but said he could have battered him over the ropes and into Capone's lap anytime he wanted. His power has never been questioned, but a career 36% KO ratio might startle many.
if ken buchanan had punching power he would be in my top 10 atg's for sure. (sorry if somebody has said this cba reading it all)
I think the inherent flaw with the thread is that punching power transforms fighters into "punchers" and they inevitably rely on their power to win the day. There are few exceptions in history where a puncher relied on technique to win the day.
Jimmy Young. Then again he had spurts of punching power like this: [ame]http://www.youtube.com/watch?v=QflZUi7kxDE[/ame] He was one of the few men to force George to the canvas, and have him at his mercy. the Punch vibrated the whole stadium and the impact made a huge sound as it connected.
I wonder why it sounded like that...? maybe because he landed it perfectly on the top of the head, scrambling foreman's brain cells. like I said if showed this punching power against other opponents-like Ali or norton, he would have decimated them all.
His workrate would suffer if he had power. Buchanan would use less movement and be more stationary if he had power. Yuh would trow less punches and perhaps be more hittable if he had power. Both of these guys would have suffered defensively if they had power. :good Power would really have helped Lamotta IMO. But he was hardly feather fisted. :good I don't think Griffith became ay more hesitant after Paret.
Winky Wright. Chris Byrd. Jimmy Young. Ken Buchanan (could have been a top 10 p4p candidate with Hamed-esque power).
