EPA per Dropback by Team

The below isolates Expected Points Added for pass plays only to get a sense of how each team’s quarterback is performing on a per-dropback basis.

EPA vs CPOE per dropback by team

The below is another way to look at quarterback efficiency using EPA and Completion Percentage Over Expectation (CPOE) as measures. CPOE is simply the difference between a quarterback’s expected completion percentage and actual completion percentage. Expected completion percentage is a stat measuring the likelihood of a given pass being completed which factors in features like depth of target (air yards). It’s a better measure of accuracy than traditional completion percentage because it takes into account the location of where passes are being thrown.

Here we focus on quarterback play only as the QB position is the most valuable position on the field. As the quarterback goes, the team goes.

Difference in Expected and Actual Yards

The below shows what quarterbacks have completed a either higher percentage or lower percentage of their passes than expected, according to the nflfastR model.

Receivers Performance

Receivers average Depth of Target (aDOT) vs. Catch Rate

The below shows receiver catch rate against their average depth of target (air yards).

Rushing Performance

The below shows a rusher’s success rate vs his total EPA gained on runs this season.
