I was nine years old back in 1975 and I was convinced the Rams would win because they finally had home field advantage in the Championship Game and Dallas was lucky on the Hail Mary pass to beat Minnesota. Ron Jaworski had been the QB that beat the Pittsburgh Steelers on Monday Night (last game of the season) and had a tremendous game against the Cardinals in the first round of the playoffs.
Knox made the decision to go with Harris because of not losing your job because of injury, but Knox should have stuck with the hot hand and Harris was rusty and threw a couple of INT's early and the game was over. Jaworski came off the bench and quickly led the Rams to a FG, which the Cowboys blocked because Tom Dempsey always struggled getting air on kicks as the Rams were blown out 37-7 and the is the last time I remember crying.
