NFL games come down to passing efficiency differential. I can't see too many universes where I like Weeden v. Belichick better than Brady v. Marinelli. And that's not a knock on us in particular, we're just undermanned right now without Dez and Tony.
Unless we take the ball away at least twice more than they take it from us, I don't see that gap narrowing. We could do it, but nothing they've done so far this season is trending that direction right now.
I think that concept is faulty.
Passing efficiency appears to be a result of winning as much as a cause for winning. If the running game is situationally great and sustains drives and scores TDs, then that helps the team to be ahead on the scoreboard. It is easier for teams that are ahead to pass efficiently. Teams that are ahead tend to be less efficient rushing because they become conservative in the 4th quarter and run the ball when it's obvious that they're going to run the ball.
The stat Rushing Yards just doesn't happen to properly represent the running game's affect on winning. The threat of the run can cause 8 in the box vs 7 which makes passing easier but that does not show up in any commonly available stats.
A defense could play 2 offenses but play 8 in the box against 1 offense and 7 in the box against the other defense. Let's say the both offenses end up with 50 yards rushing. They look identical in terms of rushing stats but the one that did it against 8 men in the box was the better rushing team.
That offense's passing game benefited by having 1 less man in coverage because of the threat of the run.
Other positive contributions to winning can end up causing a better passing efficiency. Teams can get ahead with Special Teams scores or turnovers. Again, it is easier to pass efficiently for the team that is ahead on the scoreboard while the team that is behind has to take chances in the passing game as he game progresses.
The Atlanta game is a great example. Atlanta gashed the Cowboys with the run. In the 2nd half I saw the Cowboys DEs holding up their pass rush looking for the run because Atlanta had made several big runs in the spot vacated by the DEs rushing up-field in the 1st half. Obviously, less pass rush makes it easier to pass.
