Through Week 4 of the NFL season we take a look at another PFF Elite stat, this time we focus on pass protection and our pass-blocking efficiency leaders for each offensive line position.

PFF’s pass blocking efficiency measures pressure allowed on a per snap basis with a weighting towards sacks. Overall, it’s a deeper dive into a player’s pass protection efficiency that goes beyond just the traditional sacks allowed.

Tackles:

PFF Grade: 83.6

PFF Pass Block Efficiency: 99.2

Whitworth was the position leader in pass blocking efficiency a year ago and continues his claim as the league’s top pass protector despite changing teams this offseason.

PFF Pass Block Efficiency: 98.7

Dotson is off to a hot start this season performing for an offensive line that looks improved in pass protection as a whole compared to a year ago. Dotson has kept his quarterback clean allowing just two total pressures on 115 pass block snaps: neither were hits or sacks.

PFF Grade: 82.2

PFF Pass Block Efficiency: 98.2

Penn maintains his spot as the star of the league’s best pass protecting line. For the second consecutive season, the Raiders' line leads the NFL in pass blocking efficiency and Penn is a huge reason why allowing just three total pressures and one sack on 137 pass block snaps.

Centers

PFF Grade: 85.8
