According to ProFootballFocus, the Seahawks OL through the first eight weeks of the season, is ranked dead last...
32. Seattle Seahawks (30th)
Pass blocking rank: 32nd
Run blocking rank: 29th
Penalties rank: 17th
Stud: Using the term “stud” loosely, it’s Russell Okung (60.9) for the Seahawks, the 35th-ranked NFL tackle this season. That still puts his Seahawks peers to shame.
Dud: There’s some strong competition here, but the play of Garry Gilliam (32.3) in his 515 snaps takes the win. Only five tackles have a lower grade this season.
Summary: Much has been made of the Seahawks’ struggles across the line, and you can’t say it’s unjustified. No line has a worse pass blocking efficiency score (they’ve combined to surrender 108 quarterback disruptions on 298 passing plays), and they’re not an awful much better in the run game. In Russell and Marshawn, they must trust.
