A Little More on Yards Per Attempt

Just a quick update on my previous article.

In my last article, I showed the correlation between yards per attempt and a team's offensive output. That article showed that the quarterback of the winning team had a higher average yards per attempt in 71% of games played in 2008.



Since then, I've taken the analysis one step further.
To see how strong of a driver this statistic really is, I looked at teams' winning percentage at different levels of yards per attempt differential.

Table 1a shows the results of this analysis. The x axis shows the yards per attempt differential and the y axis is the win % in situations, during the 2008 season, where the given differential occurred.

The result is incredibly linear. As the differential increased so does a team's likelihood of winning a game.
