Well, most of that book went over my head. I don‘t understand play calls and formations at all. I was hoping maybe for more general leadership/coaching wisdom. Some of the more interesting things to me were how different the NFL was in the 60s. Players had real jobs outside of football in the off-season. They referred to teams as clubs. The Packers used to share their field with high school teams. And “How to go!” was a supportive thing to say.
