The photo of Ali (Cassius) I remember is him sideshow “bought” with a Japanese wrestler. the Wrestler chose to fight by laying on his back, Ali hovering over him with his gloves on and mouth open and his tongue out.
It was a joke of a fight from start to “finish”.
I get you don't like him. Personally, I hated his mouthyness and I disagreed with a lot of his positions. But I admire his integrity in standing up for what he believed and paying the price by the rules, and I believe he was a very great actual fighter, despite his games. So portraying a joke match as summing him up is a mean spirited misrepresentation of what he legitimately earned in the sport, IMO.
