With all respect:
92 Cowboys, ranked #1 defense, #1 against the run
#2 offensive scoring
71 Cowboys #1 ranked offense in both scoring and yardage, #3 ranked defense, #1 ranked takeaways, #2 against the run
86 Giants #8 scoring offense, #10 offensive yards, #2 ranked defense scoring and yardage
If the Giants had a serious chance against either team, they would have to really pass, not the 25 passes that Sims threw, because they would have gotten nothing from their 35 rushing attempts, excluding Rutledge's 3 sitdowns at the end of the game.
....But I might give you the Commanders, it would be a fight. However, the 71 Cowboy team had Roger Staubach.....an automatic loss for the Commanders..
