Thanks to Pro Football Reference,Pro Football Focus, NFL.com, NFL Next Gen Stats and the nflFastR project for being awesome sources of data.
Previously, I analyzed the recent drop in NFL scoring, which peaked in 2020 and for three straight years has fallen back to levels that are now lower than in 2008.
I showed that this unprecedented drop in scoring is highly correlated with a reduction in passing efficiency, which is reflected in metrics like Net Yards per Dropback (NY/d).
