DALLAS (CBSDFW.COM) – The Dallas Cowboys fearsome ‘Doomsday Defense’ shutout and outscored the Detroit Lions in the NFL playoff opener in 1970. ‘Doomsday’ harassed Detroit’s offense all day long, allowing only 156 yards and forcing three turnovers.

The Cowboys defense scored when Larry Cole, Jethro Pugh and George Andrie tackled Lions quarterback Greg Landry in the end zone for a safety.

Dallas was clinging to a 5-0 lead when Mel Renfro ended Detroit’s drive deep in Cowboys territory, on the final drive of the game. “[The Lions] were marching down the field,” Renfro recently recalled about the game, “and everybody was thinking we are going to lose the big one again. Fortunately, inside the 20-yard line, I was able to get the interception. It was a great relief.”
