We’re almost at the halfway point of the year for all NFL teams, making now a perfect time to revisit our PFF offensive line rankings.Last time around (entering Week 5), Atlanta held the No. 1 spot; as the losses have crept in, however, the Falcons have slipped slightly up the list. Who has earned the O-line crown entering Week 9? Counting down from worst to best, let’s find out.(Editor’s note: Each unit’s rank entering Week 5 is in parenthesis next to the team’s name. Each player’s 2015 overall grade is denoted in parenthesis next to that player’s name, using PFF’s new 1–100 scale.)From worst to first....32. Seattle Seahawks (30th)Pass blocking rank: 32ndRun blocking rank: 29thPenalties rank: 17thStud: 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.31. Detroit Lions (32nd)Pass blocking rank: 29thRun blocking rank: 26thPenalties rank: 20thStud: The versatile guard Manuel Ramirez (83.2) has looked good whenever he’s been on the field.Dud: This year has gone terribly for LaAdrian Waddle (23.4), who has the lowest grade of any tackle and doesn’t look like the player who impressed as a rookie.Summary: What has happened to this unit? They looked like a young, developing line a year ago, but since then, they’ve regressed; pressure is flying through the line too often at Matt Stafford, and not often enough do we see holes in the run game.30. Miami Dolphins (27th)Pass blocking rank: 27thRun blocking rank: 30thPenalties rank: T-8thStud: You almost feel bad for Mike Pouncey (80.0) at times, who looks so much better than his line teammates.Dud: Pick a guard, any guard. Well, any guard named Dallas Thomas (36.3) or Jamil Douglas (28.7). Neither man has come out of the first eight weeks with any real credit.Summary: The offensive line looked like a weakness heading into the season, and so it has proved. Injuries to Ja’Wuan James and , haven’t helped, but even those two being fully healthy couldn’t overcome the play at the guard spots.29. San Francisco 49ers (22nd)Pass blocking rank: 16thRun blocking rank: 32ndPenalties rank: 4thStud: As the 49ers fall apart, Joe Staley (84.4) keeps doing his job to a high level.Dud: The fact that Marcus Martin (31.0) has the lowest grade of all centers should be a surprise to nobody.Summary: Remember when this line was one of the best in the league? That wasn’t all that long ago, and acts as a real highlight of what’s wrong with this team.28. San Diego Chargers (23rd)Pass blocking rank: 28thRun blocking rank: 25thPenalties rank: 27thStud: There’s no denying that Joe Barksdale (84.9) has proved a great pickup, even if the team hadn’t suffered all the injuries they had.Dud: Injuries have forced guys to play who really shouldn’t have: Trevor Robinson (28.2), chiefly.Summary: Every year, the Chargers seem to pick up more and more injuries on the line. Is it bad luck, or something about the guys on the roster? Whatever it is, it’s the main factor in such a low ranking.27. St. Louis Rams (25th)Pass blocking rank: 25thRun blocking rank: 28thPenalties rank: 28thStud: First-year player Rob Havenstein (73.1) doesn’t look like a rookie.Dud: Sophomore Greg Robinson (34.4) does look like a rookie.Summary: There’s some talent on this offense, but this line is making them really max it out with their up and down efforts. We mentioned Robinson as the dud, but it’s a worry that he doesn’t seem to be progressing.26. Tennessee Titans (17th)Pass blocking rank: 30thRun blocking rank: 22ndPenalties rank: 26thStud: Beaten for five sacks, Taylor Lewan (77.2) is the standout player on this line.Dud: Jeremiah Poutasi (39.5) started out well, but team’s are beginning to understand how to play him.Summary: The Titans’ offensive struggles start up front, where Poutasi is outmatched, Chance Warmack is flirting with bust status, and injuries cripple the interior. When you invest as much in the line as the Titans have, this is a poor return.25. Washington Redskins (31st)Pass blocking rank: 21stRun blocking rank: 31stPenalties rank: 24thStud: As ever, the stud remains Trent Williams (86.9).Dud: He’s been a little better recently, but Kory Lichtensteiger (19.1) just hasn’t played well this year.Summary: While the tackles have played well, the interior has struggled, especially in pass protection. That’s disappointing, especially given the high pick of Brandon Scherff.
24. Tampa Bay Buccaneers (28th)Pass blocking rank: 19thRun blocking rank: 23rdPenalties rank: 32ndStud: He’s not the player he once was, but Logan Mankins (77.9) is still playing well.Dud: It’s not been easy for Donovan Smith (33.2), who needs to do better in the run game.Summary: If you’ve got a problem on this line, it’s both tackles, who each rank in the bottom eight of offensive tackles. That worries you about Gosder Cherilus, who might be coming to the end of his run.1. Dallas Cowboys (4th)Pass blocking rank: 2ndRun blocking rank: 1stPenalties rank: 31stStud: Each of the former first-round picks on this line have made a strong case to be the stud, but how you can look past Tyron Smith (94.8, who has allowed just four hurries all year?Dud: This could be the last year for Doug Free (47.0), who has struggled for consistency this year.Summary: The Cowboys’ investment in their line continues to reap dividends. First-rounders Smith, Zack Martin (92.9), and Travis Frederick (89.5) are all guys who should be hearing their name in All-Pro and Pro Bowl conversations. Now, if only they could get Tony Romo healthy.For the complete list......link
