Before last season, in a piece about the relative importance of a pass rush, I took a closer look at the degree to which pass rushing proficiency versus pass blocking proficiency was a predictor of team success:
Another 2019 study, this time by analysts at ESPN, looked at the importance of pass blocking versus pass rushing, utilizing 2.5 seconds as the threshold for either pass blocking success or failure. Using the “pass block win rate” (PBWR) and “pass rush win rate” (PRWR) metrics they had developed from NFL NextGen Stats, derived via player tracking data, they looked at the winning percentages for teams that excelled in each.
