Having said that, I'll reiterate here what I've said multiple times in these threads and *still* haven't gotten a good response to. This strong offensive production was almost certainly a function of having played a weak schedule and endured a relatively low number of injuries. Put this year's offense against an average schedule and saddle them with an average amount of injuries and the production would have been average, at best.
There's so much grey area there that it's hard to address, and I don't think anybody's going to give you a response that will satisfy you. We played 8 games against defenses that ranked in the top half of the league in points allowed per drive, and 8 against teams that ranked in the bottom half. Since all we have to go on is the schedule that was actually played, then if we were an average offense, it stands to reason that we'd have scored about what the average team scored against these defenses.
In our 8 games against teams with defenses that ranked in the bottom half of the league in points allowed per drive, we scored 225 points on 90 drives, an average of 2.50 per drive. On average, these teams gave up 2.13 points per drive. So the Dallas offense scored 14.8% more than the rest of the NFL did against these defenses. If Dallas' offense was average, the difference should then be seen in how it performed against the better defenses it faced.
In our 8 games against teams with defenses that ranked in the top half of the league in points allowed per drive, we scored 174 points on 93 drives, an average of 1.87 points per drive. On average, these teams gave up 1.66 points per drive. So against these better defenses, Dallas scored 11.3% more than the league did. This was not an offense that beat up on the bad defenses it faced and was exposed by the good ones.
