John I'm real impressed that you read a book. Got to ask if you made it all the way through, you don't seem like that kind of a guy! Just looking at all of the pictures doesn't count.
I have read and studied dozens of books concerning how to do many things. Many by multi-time world champions and people in various halls of fame. I have yet to find one source that had 100% of the information and was 100% accurate. People who want a narrow perception of the world can accept one source as having all information. They remain ignorant of quite a lot though.
You can do the research if you really care, I think it was someone in Willie's family, probably his wife, that said they became friendly. Could have been Cosell, it isn't the most important thing I remember. It has been said they became friends, who knows? Bush the first and clinton became friends once they were both out of office despite clinton representing pretty much everything Bush disliked both as a person and politician. When you are in a very small and elite group you either become friends or quite bitter enemies when you are thrown into contact over and over.
Some friends I have on AZB and later in person were met originally on opposite sides in a thread. We all had the ability to think and grow. Of course there is at least one or two that will remain a dipshit for life, some people are born and raised that way, can't be helped!
