Today I am continuing my “Offensive Line Study Series”, here is a link to the first study that I would recommend for full context of this study:
I wanted to dive deeper and get a broader view than a single season. I also wanted to answer this question: How did the players grade according to stats from Pro Football Focus (PFF) and Sports Info Solutions (SIS) in the last five years?
Here are the definitions for the datapoints used in this study:
- PFF Run Block Grade (RBLK) = PFF Grade for Run Blocking
- PFF Pass Block Grade (PBLK) = PFF Grade for Pass Blocking
- SIS Total Points Earned (TPE) = The total of a player’s EPA responsibility using the Total Points system
Some important things before the graph, the players in this study are the leaders in single season TPE with the highest snap counts (for durability), then layering in the PFF grades and TPE from 2016-2020.
