I never watched him in person, only on tv. as Don mentioned, I always heard that he was a late night boy - loved the ladies, too, and they him.
I do remember an interview with him where he was asked about his drinking and late night carousing. his response was something like, "I don't need a lot of sleep. I can get by with only a few hours. How much sleep do you need anyway to go out on Sunday and play for a few hours?"
and then this one, which i think captures Kenny's life style back then. "I even often have read Sunday's game plan by the light of a jukebox."
on play-calling, I remember a sideline video where Madden said to Stabler, "I don't care what you call, just get it in."
Art Shell always called him "My Alabama Boy."
