Sealed Knox's fate and his luck in post season. I was never a fan of Pat Haden anyway, wish they had kept Jaworski instead. But Chuck Knox had nothing to do with the weather, but he was very unlucky in post season and it was his last game as Head Coach of the Rams. Rosenbloom wanted to make the change before 77, but he didn't want Knox to end up in Detroit so he kept him one more year.
FWIW I was 11 and when I heard about the weather and saw the field, I knew there was no way the Rams were going to win that game.
