As a kid I competed in USA/ABF ametuer boxing. My father was the coach. He use to refer to Macho Comacho as a teaching tool for me and local boxers. Macho was a great south paw. Macho was a good example of how to fight and defend against lefties.
Macho,'s winner attitude and prefight confidence especially when you have an upcoming bout against an opponent who has already beaten you before was a valuable lesson to which every boxer should pay attention,
"It is possible to convince some fighters you're still better than them, even if they beat you in the past. In boxing it is very important to have short-term memory." --Cody Coughran
