I loved listening to Hank Stram who was great but Madden was a teacher (he had done graduate studies in psychology I think).
I remember Madden pointing out stuff that just happened that I didn’t know just happened - why that last play was so successful or what happened to stop that last play - stuff the usual broadcaster totally missed and/or just didn’t talk about.
John Madden helped me watch the game better and have fun doing it. He was fun. Summerall didn’t seem to know what to do with him. I loved his “boom”’s and his “doink”’s and the stuff nobody else would talk about that was woven into the fabric of football. It was like one of my buddies sitting there making jokes while we were watching the game. Madden was just one of the guys. I loved it.
For me, watching and listening to Madden was to football like going to Fenway Park for baseball - both reeked of the sport they were about.
I’ll I remember is remarks about dirty uniforms, grass stuck in the face mask, and turkeys with a bunch of legs. Never anything of substance.
