Yes, I remember that also. I don't remember who the assistant trainer Foreman brought in was. I remember Clancy saying "the last thing George needs is more muscle". Clancy wanted Foreman's training to revolve around roadwork and sparring. He also wanted Foreman coming in lighter. Louis said he felt Foreman should try to come in as light as 210, which is very light indeed. I don't know why George did that. He was a bit of a headcase back then.
George at times seemed to smart for his own good, or at least he over thought things. He would have better off if he had started off with Gil Clancy instead of D1ck Sadler.
For anyone who might be interested, I'm working on a Youtube playlist of fights that included Gil Clancy on commentary. Showcases a number of good fighters mostly from CBS broadcasts of the 80s. Gil was an awesome color man, listening to him has basically been an ongoing boxing education for me. https://www.youtube.com/playlist?list=PLi4X90QIQXb7KYeonF7wksPGWNvSrENxD
I remember reading that he said he thought Quarry was the best, most natural puncher he ever trained.
I liked his broadcasts. He talked techniques. I remember when Hagler fought Mugabi, he said Marvin was rusty and his left was not straight. I learned a lot with Gil. I thought he was one of the best.
Yeah, I thought that was an interesting tidbit too. No, he said "puncher." You're right, the hook was Quarry's thing but Clancy was speaking more generally.
