No, and that's a fair point. but as I mentioned in my original post I'm not claiming the numbers show cause or effect. I was actually responding to the following which seemed kind of superficial:
"For games where they had <200 passing yards, teams won 44% of their games & scored an avg. of 17.7 pts per game. For 200-299 passing yards, teams won 52% of their games & scored an avg. of 23.3 pts per game. For 300+ passing yards, teams won 55% of their games & scored an avg. of 29.0 pts per game.
To me, it looks like passing yards have a strong relationship with winning"
I expanded on that and included rushing just because I was interested and was surprised at the contrast.
For the record, my preference would be we run for 120 and pass for 320 every game
