Thanks Percy, You find some good stuff related to dallas stats. I hope you don't find the following as a challenge - just an opinion. I posted a long analysis about this topic around week 13 last year. The crux is that Dallas and Denver were outliers to overall ebb and flow. I initially did this analysis to see if I could gain an advantage at the sport book. And I did better than 65% selling dallas and denver in the first half and buying in the second half. starting around week 7.

I don't think this is assumption would be completely valid. First, there is a pretty small sample size of "drives when leading." That denominator equates to 14 TDs when leading and I assume would include First quarter Dallas leads of 3-0 which may turn to 3-7. Secondly, I would anticipate opponents yards to be higher if you play with a lead. They will be taking more shots. I would also expect that the defense would force more turnovers as they are keying in on the offense having to be one dimensional. Neither turnovers of making the opponent one dimensional were the cornerstone of dallas last year. Some of that was defensive injuries, some was the offense not being in a better position to press the opposing offense to score. In that thread, I believe I noted where Dallas was one of the best defenses in opponent first half scoring. That is washed away when your offense is 31st in first half scoring (trailing only KC). That may have changed in the last 2 weeks of the season, but not much.
I will agree that it seems to be statistically significant that passing efficiency and defending the pass is highly correlated with wins. however, as mentioned above there are outliers in every statistical analysis. Football, unlike baseball, is rather difficult to have a few stats be a baseline in all scenarios. I have spent way too many hours trying. There is some interesting work, but, as you know, each play in football is not homogenous, and it is hard to assign full season stats to prove or refute any situational assertion as the sample size is usually not large enough (i.e. personnell, plays, opponent, score, time in game, etc.)
You've done a ton of work on this, and I think without a doubt you've shown that teams that win the first half are more likely to win the game. Getting off to a strong start in a game offensively helps you win more games, because it means you have more points. While this gives the defense the advantage of a cushion, the data sure seems to show that playing with a lead didn't improve their performance on any given drive last year. By scoring more points, you've improved your team's chances of winning, but improving your team's chances of winning isn't the same as improving the performance of your defense. Maybe with a greater sample size, we'd see some defensive improvement. With a greater sample size of Dallas playing with leads, we'll see more wins either way.
