They barely missed dominating the 70s.
LOL....The Steelers crushed the Cowboys in both Super Bowls in 1975 and 1978. There was no "barely missed" against the Steelers.
The Cowboys were down by 18 late in the 4th quarter of Super Bowl XIII, then the Cowboys scored garbage points at the end of the game when the Steelers went into their prevent D.
Same thing with Super Bowl X. The Steelers were up by 11 late in the 4th, then the Cowboys scored garbage points at the end of the game when the Steelers were in their prevent D.
The Steelers dominated the 70's, especially against the Cowboys.
The Steelers sacked Roger Staubach 7 times in Super Bowl X. A record that still has not been broken.
You want to talk about "barely missed"?
Had Bradshaw not gotten hurt and taken out of the 72' AFC Championship Game, the Steelers would have won the Super Bowl in 1972.
Had Franco Harris not broken his ribs in the AFC Divisional Game in 1976, and missed the 76' AFC Championship Game, the Steelers would have won the Super Bowl in 1976.
IOW, the Steelers "barely missed" winning 6 Super Bowls instead of the 4 Super Bowls they won in the 70's.
