I stumbled upon a site new to me called the 33rd Team. I thought maybe some may like some of their content.

They have a section called yards per play differential. Here's their description:
Football is a turf war, and this is how you measure it.
For years, one of the stats analysts and gamblers love to use in assessing how good or bad a team is performing is yards per play differential. While it sounds complex, it’s pretty simple.
How many yards does your offense gain on the average play vs. how many yards does your defense allow per play? If you hope to win or even get to a Super Bowl, the difference better be positive. This is a measure of how teams play on a down-by-down basis where the impact of one or two big plays or flukey circumstances can impact the results.
