Interestingly, the idea that you need to run to "wear a defense down" appears to be false. However, there is a big correlation between 4th quarter rushing attempts and winning. See: http://www.footballoutsiders.com/2003/07/14/ramblings/stat-analysis/3/
Now I'm not saying that you don't need to run the ball effectively to win, just that you can start to think a little differently about the game.Real football... my specialty. Let's discuss the logic of this.
From the bottom up:
Of course 4th quarter rushing yards corelates to winning. If you have the lead, you'll run out the clock.
Also, of course passing efficiency relates to winning. As far as attempt/int goes, one turnover is probably as devastating, if not more, than getting a game broken in tennis. You only get x chances on offense to win the game, and if you lose one of them and give the other team good field position, the odds of you winning are much less.
You have 3 chances, realistically, to get a first down (starting at 1st down). If you throw on first down and it's incomplete, you have to average 5 ypp (realistically just slightly over that usually) to get a first down. It's the same in baseball as having your leadoff man not make it to first. It takes away a lot of the playbook. Keeping with baseball, if you have a guy on 2nd and 0 out, you can sac bunt then sac fly, relatively routine plays in the mlb, and get a run in. With a man out, you have to get someone to third before you can think about sacrificing. Going back to football, this parallels in that if you run on first and have even like 2nd and 6, you only have to average 3 ypp. You can run a simple hitch route and pick up a first down there. You have all kinds of plays at your disposal since you don't have to take a high risk, high reward play. You still CAN, and that keeps you dangerous.
I know you're just providing stats but I mean it's all really logical and, when you think about it, passing efficiency / 4th quarter rushing = win... not a reach at all.
However, does that site argue against a run-first defense being less important than a pass-first defense? If you look, the Pittsburgh Steelers have been near the top in the league in rush stopping the past few years, and they have also been near the top in total defense (#2/#1 in '07 iirc). I would think making a team have to throw would be a better objective than allowing the run. Look at teams like Denver... when Denver failed to stop the run in '07, that's when EVERYTHING fell apart... even with the league's best CB tandem (or top 2 with GB, but I'd still say, out of credentials, Denver had the best).
Edit: For these reasons, I find yards per attempt (rushing/passing) to be much more effective indicators of a good offense/defense. If I run 50 times and get 150 yards, that's a good day in total yards, but that's still (on average) 3 plays that won't net a first down. Shaun Alexander had 50 rushes for 200 yards against the 49ers in like '06 and people were saying "wow 200 yards" and stuff but that's not even a good game imo...
