After the preseason, the Steelers, Cowboys, Eagles, Saints and Ravens ranked on the top of this list – these are all very familiar names when it comes to discussions about the best offensive lines in the NFL and they also have some of the strongest left tackles in the league. A common denominator for the top 5 pass-protecting lines through 4 weeks is that their left tackle has an 80+ pass-blocking grade so far this season.

I will score each team like I did after the preseason: a teams score is the average pass-protecting PFF grade for each starting member of the offensive line. Although the top 5 teams in the preseason were not unexpected, this ranking should be more accurate and telling because the sample size is much bigger.

1: Baltimore Ravens (76,94. Preseason rank: 5)

Through 4 weeks only one player (Ryan Jensen, center, Buccaneers) has a higher pass-blocking grade than the Ravens’ left tackle Ronnie Stanley. Veteran guard Marshal Yanda is other standout performer on a line that really does not have any major weaknesses.

The Ravens’ offense is centered around rushing and taking deep shots downfield off play-action. An elite offensive line has allowed them to do this with great success and rookie WR Marquise Brown and TE Mark Andrews have been the main beneficiaries. Brown has been a very positive fantasy surprise for me, as he is getting both a high volume (30 targets in 4 games) and deep targets (10 targets beyond 20 yards). As long as the offense can stay efficient, QB Lamar Jackson will also remain a very good fantasy option.

2: Kansas City Chiefs (74,8. Preseason rank: 26)

The Kansas City offense has continued where it left off in 2018. By holding up in pass-protection they allow the receivers time to get open and Patrick Mahomes to throw from a clean pocket. Combine this with one of the best play callers in the league in Andy Reid and you have the best offense in the NFL.

With the amount of weapons this offense possesses it is difficult to rely on many of them week after week, as the receivers have taken turns having huge games thoughout the first month of the season. TE Travis Kelce remains the most stable option.

3: Dallas Cowboys (73,72. Preseason rank: 2)

The return of center Travis Frederick was a big boost for this team in the offseason, but so far he has not played up to the level he did before his injury (earning just a 60,6 pass-protection grade so far), but La’el Collins has stepped up big-time and has arguably been the best tackle in the entire league through the first 4 weeks (88,3 run-blocking grade and 77,8 pass-protection grade). It will be interesting to see how they deal without left tackle Tyron Smith in the coming weeks, when Cameron Fleming will fill in for the injured starter.

Until they faced the Saints in week 4, the Cowboys looked like they had one of the best offenses in the league. Dak Prescott has played as well as he has at any point in his career and his weapons are arguably better than ever. New OC Kellen Moore has impressed with his play-calling so far and the offense as a whole looks greatly improved from last year. WR Amari Cooper has been an elite fantasy receiver so far and he doesn’t look like slowing down any time soon. Returning TE Jason Witten has a solid 14 receptions through 4 weeks, but he has very little upside.

4: Philadelphia Eagles (73,70. Preseason rank: 3)

There isn’t really much to say about this Eagles line that many people haven’t said already. They have elite players at every position except left guard, which has been a big weakness for them so far. LT Jason Peters might be aging and regressing slightly, but rookie Andre Dillard was arguably the best pass-protecting tackle in this years class and he should be ready to be a very solid starter before too long.

Until his injury in week 2, DeSean Jackson torched the Redskins in week 1, and he looks like he still has what it takes to be a very solid fantasy performer. I have never been very high on Alshon Jeffery, but he remains the number 1 WR on the team and should continue to be productive. I think QB Carson Wentz has played a lot better than his statistical output has shown so far, with many of his best throws falling incomplete because of drops.

5: San Francisco 49ers (72,66. Preseason rank: 10)

Veteran LT Joe Staley continues to play at an elite level (86,8 pass-blocking grade), but RT Mike McGlinchey has not played as well as he did as a rookie. His regression has mostly been in the run-game, so he remains solid as a pass-blocker. This is a line without any weaknesses (their grade of their weakest starter this year is 66,9, which is the highest in the league).

TE George Kittle remains the focal point of the passing attack, while WR Dante Pettis has failed to break out so far this season. Pettis ranks 6th on the team in targets with just 6. Rookie Deebo Samuel leads the teams WRs in targets (14) and receptions (11) and I’m very high on him going forward.

6: Pittsburgh Steelers (71,02. Preseason rank: 1)

7: New England Patriots (70,36. Preseason rank: 6)

8: Arizona Cardinals (70,34. Preseason rank: 27)
