Yeah, it's a really good interview with Ali; he manages to be funny while setting out his plan to beat Foreman. Incredible, when you think about what he had just witnessed.
The first time I saw in person a Mexican left hook to the liver by a specialist Chango Carmona vs Ohio's Doug Agin. I am from NYC, and used to go to all the Garden fights. When the Air Force put me in San Antonio, I went to see the fights, and what greats I saw, up to that time I had only seen Mexicans on the Spanish station in NY. What a difference "live" makes. The moment Agin went down from that left hook, it was over. I had not seen that affect before, the pain Agin was in. IDK if it's just me Mexican's really know how to throw that liver punch.
I remember my Dad and his friend discussing Liston-Patterson I before it happened, so that would be the first for me.
