I found this guide on the internet. It does a great job addressing the basics of the receiver position. I had been watching a lot of videos and reading various articles about receiver fundamentals, and I found this guide did a great job filling in some of the details.
I don’t know who wrote the guide. I wish I did so I could discover if he has more material for purchase. The guide is title. Chapter Two so it must be a part of a larger book. Would love to buy that book.
