We started with a question: Which NFL team has the best -- and worst -- pass-blocking offensive tackle duo?
And thanks to our new Pass Block Win Rate metric, which uses NFL Next Gen Stats, we have an answer.
The league's best tackle combo won't surprise you, as the Los Angeles Rams have the NFL's best offense -- and offensive line. And the worst pass-blocking tackle duo? It's the New York Giants, who have the NFL's worst offensive line as a whole, according to PBWR, including the league's worst two tackles.
Let's rank the OT combos from 32 to 1 using PBWR -- read the explainer on how it works here. In cases in which tackles have been benched or gotten injured, we're using the players who are expected to be the starters for the rest of the season. Another note: Some tackles haven't played enough snaps yet to qualify.
32. New York Giants
Left tackle: Nate Solder (66 percent Pass Block Win Rate)
Right tackle: Chad Wheeler (54 percent)
Not only do the Giants' tackles average the worst PBWR in the league, but they have been the first- and second-worst individually among all tackles with at least 100 pass blocks this season. With Wheeler, a former undrafted free agent out of USC, it's a problem. With Solder, whom the team signed to a four-year, $62 million deal in the offseason, it's a disaster.
It often doesn't seem like the Giants' pass protection is quite as bad as it is because Eli Manning tends to get rid of the ball relatively quickly. That's where the strength of PBWR comes into play; it considers pass-block survival relative to time after snap. And when Manning holds the ball, there's usually trouble waiting for him.
31. Arizona Cardinals
Left tackle: D.J. Humphries (71 percent)
Right tackle: Andre Smith (67 percent)
In Thursday night's blowout loss at the hands of the Broncos, Arizona's offensive line posted the fourth-worst team PBWR of the season. Both Humphries and Smith posted below-average PBWRs in the loss. To be fair to Smith, though, he had to contend with Von Miller.
30. Detroit Lions
Left tackle: Taylor Decker (70 percent)
Right tackle: Rick Wagner (73 percent)
Decker ranked among league's best tackles in PBWR in his eight games last season, while Wagner was above average. That has not been the case in 2018.
29. Cincinnati Bengals
Left tackle: Cordy Glenn (73 percent)
Right tackle: Bobby Hart (72 percent)
How badly do you think the Bengals wish they'd hung on to Andrew Whitworth, who left in 2017? While their former left tackle is thriving in Los Angeles with the Rams, the Bengals' duo is struggling.
28. Oakland Raiders
Left tackle: Kolton Miller (71 percent)
Right tackle: Brandon Parker (75 percent)
Jon Gruden & Co. are relying on a pair of rookies to protect Derek Carr; Miller was a first-round pick, and Parker was taken in the third-round. Neither has been good in pass protection so far, though Miller has dealt with a knee injury.
27. New England Patriots
Left tackle: Trent Brown (81 percent)
Right tackle: Marcus Cannon (68 percent)
Cannon had a particularly rough Week 4 against Cameron Wake and the Dolphins; he posted just a 55 percent PBWR.
26. Jacksonville Jaguars
Left tackle: Josh Walker (70 percent)
Right tackle: Jermey Parnell (82 percent)
Even if the Jags decide to insert new addition Ereck Flowers into the lineup, he isn't likely to help much. The former first-round pick had a PBWR of 71 percent with the Giants this season and a 74 percent in 2017. Then again, after a couple of injuries at left tackle, the Jaguars don't have a ton of talent with which to work.
25. Atlanta Falcons
Left tackle: Jake Matthews (80 percent)
Right tackle: Ryan Schraeder (74 percent)
Schraeder's worst pass-blocking game was the season opener against the Eagles. In an 18-12 Falcons loss, he had to contend with Chris Long, Brandon Graham and Philly's stellar pass-rush rotation.
24. Minnesota Vikings
Left tackle: Riley Reiff (77 percent)
Right tackle: Rashod Hill (80 percent)
Kirk Cousins went from a Redskins team with poor pass-blocking in 2017 to ... a Vikings team for which it is still an issue. The interior of the Minnesota line has been worse.
23. Los Angeles Chargers
Left tackle: Russell Okung (78 percent)
Right tackle: Sam Tevi (79 percent)
For a backup, Tevi has been solid in pass protection, filling the void left by Joe Barksdale, who suffered an injury in Week 1. Barksdale, who didn't start but did play a few snaps on Sunday, protected Philip Rivers at a slightly better rate last year (82 percent) than Tevi has this year.
22. Houston Texans
Left tackle: Julie'n Davenport (79 percent)
Right tackle: Kendall Lamm (79 percent)
Davenport was actually benched in favor of Lamm on the right side earlier this season after struggling in the Texans' first few games, especially at Tennessee in Week 2. Davenport was installed at left tackle in Week 5, however, and has played better since then.
21. Carolina Panthers
Left tackle: Chris Clark (72 percent)
Right tackle: Taylor Moton (87 percent)
Carolina lost both its left and right tackles -- Matt Kalil and Daryl Williams -- to injuries before the season. Moton, a second-round pick last year, has been a revelation so far. He was the sixth offensive lineman taken in the 2017 draft but is proving to be one of the league's best pass-protectors.
20. Philadelphia Eagles
Left tackle: Jason Peters (78 percent)
Right tackle: Lane Johnson (81 percent)
The 36-year-old Peters is a future Hall of Famer, but perhaps age is finally catching . He hasn't been bad, but his pass protection has merely been league average. Though we don't have PBWR data for most of his career, it's probably safe to assume that average isn't up to his standard.
19. Baltimore Ravens
Left tackle: Ronnie Stanley (83 percent)
Right tackle: James Hurst (78 percent)
The Ravens' offensive line was outstanding in the team's Week 4 win in Pittsburgh. Stanley, facing Bud Dupree more than anyone else, sustained his block on 97 percent of plays in which Joe Flacco held the ball for 2.5 seconds or more.
18. Tampa Bay Buccaneers
Left Tackle: Donovan Smith (80 percent)
Right Tackle: Demar Dotson (82 percent)
Dotson and Smith both led the way in the Bucs' best pass-blocking game of the year so far -- the team's Week 1 win over the Saints, which was the start of Ryan Fitzpatrick's magical hot streak.
17. New York Jets
Left Tackle: Kelvin Beachum (84 percent)
Right Tackle: Brandon Shell (79 percent)
Jets general manager Mike Maccagnan moved up in the 2016 draft to draft Shell in the fifth round, surrendering a future fourth-rounder in the deal. Getting a league-average pass-protector with that minimal investment is a nice value.
16. San Francisco 49ers
Left Tackle: Joe Staley (84 percent)
Right Tackle: Mike McGlinchey (80 percent)
Getting average pass-blocking production out of rookie first-round pick McGlinchey is a good sign for protecting Jimmy Garoppolo in future seasons when the franchise quarterback returns to action.
15. Dallas Cowboys
Left Tackle: Tyron Smith (80 percent)
Right Tackle: La'el Collins (85 percent)
Though Dallas might not be quite the offensive line force it was a couple of years ago, it still has the same solid foundation. That's Smith, Collins and Zack Martin, who ranks seventh in PBWR among guards with at least 100 pass blocks this season.
14. Indianapolis Colts
Left Tackle: Le'Raven Clark (73 percent)
Right Tackle: Braden Smith (92 percent)
Anthony Castonzo is now back in action, but he has played in only two games and didn't qualify. He posted a PBWR of 85 percent last season, so if Smith, a rookie second-round pick, can keep up his hot start the Colts might have a nice pair of tackles.
13. Cleveland Browns
Left Tackle: Desmond Harrison (81 percent)
Right Tackle: Chris Hubbard (85 percent)
Though he hasn't been the better part of the Browns' tackle combo, that Harrison put up a league-average PBWR as a rookie undrafted free agent is remarkable. The Browns have been a good pass-blocking team but appear worse because Baker Mayfield and Tyrod Taylor have held the ball longer than the average quarterback.
12. New Orleans Saints
Left Tackle: Terron Armstead (77 percent)
Right Tackle: Ryan Ramczyk (88 percent)
Ramczyk, who slid to the final pick of the first round in the 2017 draft, looks like a high-end pass blocker in Year 2. Among tackles with at least 100 pass blocks this season, he has the fifth-best PBWR.
11. Denver Broncos
Left Tackle: Garett Bolles (84 percent)
Right Tackle: Jared Veldheer (82 percent)
Bolles, a first-round pick in 2017, was solid in pass protection in his rookie season (78 percent) but has taken a step forward in Year 2. The veteran Veldheer is showing a major improvement compared his performance last season in Arizona (74 percent).
10. Washington Redskins
Left Tackle: Trent Williams (85 percent)
Right Tackle: Morgan Moses (82 percent)
Williams had a down year in 2017, posting a below-average PBWR of 77 percent. That number is back up to where you'd expect for the six-time Pro Bowler, and Moses' win rate is up a bit, too.
9. Chicago Bears
Left Tackle: Charles Leno Jr. (85 percent)
Right Tackle: Bobby Massie (82 percent)
Leno has been solid protecting Mitchell Trubisky's blind side, but he struggled against Chandler Jones. In the Bears' narrow Week 3 win over the Cardinals, Leno's PBWR was just 67 percent.
8. Kansas City Chiefs
Left Tackle: Eric Fisher (79 percent)
Right Tackle: Mitchell Schwartz (89 percent)
One weakness of PBWR is that it doesn't adjust for opponents. That's OK over the course of a season, but it can have a big effect in a single game. That didn't matter for Schwartz against the Broncos earlier this season, when he posted a 96 percent PBWR in a game in which he mostly squared off against Von Miller.
7. Tennessee Titans
Left Tackle: Taylor Lewan (86 percent)
Right Tackle: Jack Conklin (82 percent)
The Titans' first-round investments in Lewan (2014) and Conklin (2016) are paying off. Both ranked near the top of the PBWR leaderboard last season, too.
6. Pittsburgh Steelers
Left Tackle: Alejandro Villanueva (83 percent)
Right Tackle: Marcus Gilbert (87 percent)
The Steelers were the best pass-blocking team in the league last season, per PBWR. Their two tackles are still solid, but Villanueva and Gilbert have moved down to No. 6 in 2018.
5. Seattle Seahawks
Left Tackle: Duane Brown (87 percent)
Right Tackle: Germain Ifedi (83 percent)
That's right, the Seahawks can block! We wrote previously about how the pressure on Russell Wilson has more to do with the quarterback's playing style than the skill of the blockers in front of him.
4. Buffalo Bills
Left Tackle: Dion Dawkins (85 percent)
Right Tackle: Jordan Mills (85 percent)
It's amazing the Bills can have tackles this good at pass protection on an offense that is so bad. Dawkins was selected one spot before the Panthers took Moton in the second round of the 2017 draft.
3. Miami Dolphins
Left Tackle: Laremy Tunsil (87 percent)
Right Tackle: Ja'Wuan James (85 percent)
What's amazing about the Dolphins is that they are one of the worst pass-blocking teams in the league despite having two good blockers bookend their line. The interior of that unit is extremely weak.
2. Green Bay Packers
Left Tackle: David Bakhtiari (92 percent)
Right Tackle: Bryan Bulaga (90 percent)
If it weren't for the Rams' absurd tackle production, Green Bay would look incredible here. Even still, Bakhtiari and Bulaga rank second and third among tackles in PBWR.
1. Los Angeles Rams
Left Tackle: Andrew Whitworth (93 percent)
Right Tackle: Rob Havenstein (90 percent)
The Rams are on another planet. And it's not only these two tackles -- who rank first and fourth in PBWR at the position -- but the entire offensive line. Todd Gurley and Jared Goff deserve plenty of credit, but they are fueled by an offensive line that is doing something amazing.
