Offensive line play is where PFF’s methodology really shines.
The data is so thin on the ground for the big men up front that if you simply document how players perform on every play in every NFL game, you completely transform the level of information available compared to any other position.
Until PFF came around, the narrative around offensive linemen was largely driven by a few highlight-reel plays, reputation and some misplaced indicative stats like how often the quarterback was sacked or how good the team’s rushing attack was. We know how flawed those numbers can be now, whether it be for a unit overall or for an individual member of that line in particular.
