Re: Gerry Cooney - the hardest puncher ever?
Foreman said Lyle. Young said Shavers. Lyle said Shavers. Norton said Shavers. (Holmes admitted after their match that Cooney was never able to connect solidly enough for him to make an honest assessment of Gerry's true power.)
Gerry landed some solid hooks to Young's body, and Jimmy responded by coming forward. Young was decked by the hook of Shavers, and it was a hook Foreman used to seriously stun Jimmy. (His hook also rang Chuvalo's bell. Like Shavers, Foreman was a huge puncher with both hands.) At no time did Cooney's power hurt him like this.
I think a case could be made that Cooney was a harder hooker than Morrison. Gerry clearly affected Foreman more with a single short inside hook than Tommy was able to do with 12 rounds of bombs. Yes, he was a great puncher, but there's nothing to suggest he was the hardest of them all.
