2018 Cowboys Postgame Reports

Pasted Graphic
For the third-straight year, after every Dallas Cowboys game, I will provide an analytical graphic to begin the conversation as to why the Cowboys won or lost that particular game. However, this year features a new look and simplified visualizations so it's easier to follow and compare what happened. Our graphic is an example from the Cowboys preseason game against the Cardinals.

There are four factors:

- Turnover Margin
- Scoring Efficiency
- Net Yards/Pass Attempt
- Game Control

Our intelligent readers already know what Turnover Margin is, so we move on to Scoring Efficiency, which is essentially points divided by yards. Here, we include percentages, so the more efficient team earns the 100% margin, and the less efficient team shows the fraction of its efficiency compared with its opponent.

Net Yards/Pass Attempt is (passing yards - sack yards) / (passing attempts + times sacked). Because of the reliability of this metric not just to evaluate quarterback performance but also its consistency over time, this serves as an important metric to include.

Lastly, Game Control is based upon a regression where each explanatory variable is the number of rushing yards per quarter and the dependent variable is the likelihood of winning. My research found, predictably, that rushing yards in later quarters matter more to winning than earlier in games. Here, we add up each team's rushing yards and multiply by a factor for each quarter they were rushed in. We then take those results as a proportion to see how much each team controlled the game.

As always, feedback is appreciated!
