Depth: Lane Taylor, Lucas Patrick, Jon Runyan Jr. (R), Jake Hanson (R), Simon Stepaniak (R)
Despite returning four of five starters, the Packers' line drops one spot from their 2019 rank due to the loss of longtime starter Bryan Bulaga in free agency. Green Bay found a suitable replacement at right tackle in Rick Wagner, but he took a major step back in 2019 to cause legitimate concern over the possibility he's declining at 31 years old.
David Bakhtiari is a star on and off the field, earning PFF's second-highest pass-blocking grade among tackles last season while entertaining fans with courtside chugging skills during his off time. Bakhtiari is the anchor of this group and overshadows an underrated trio on the interior. Elgton Jenkins is coming off a strong debut campaign. Corey Linsley is one of the better centers in the league. Billy Turner is a versatile lineman who's continued to improve thanks to the talent around him. Let's hope the arrival of Wagner doesn't cause a negative reaction on the right side of this line.
The pass blocking has been top shelf for some time in Green Bay. However, with Aaron Rodgers being asked to perform more of a game-manager role in Matt LaFleur's system, this passing attack is no longer one to invest in for fantasy outside of Davante Adams, who might lead the league in targets.
9. Philadelphia Eagles
Depth: Matt Pryor, Jordan Mailata, Jack Driscoll (R), Prince Tega Wagano (R), Nate Herbig
The Eagles would have occupied a top-four slot on this year's list had it not been for the torn Achilles suffered by three-time Pro Bowl guard Brandon Brooks in June. With Brooks out for the season, the Eagles brought back a familiar face in 38-year-old Jason Peters. The shift to guard won't be seamless, but Peters is athletic enough - even at his age - to perform well in this unexpected relief role.
Outside of Peters' move to guard, the only other question mark is Andre Dillard taking over Peters' old spot at left tackle. Dillard comes with a first-round pedigree and should grow into the job, even if it involves a slight adjustment period.
It's tough to repeat the success this line had in 2019 when four of their five starters graded out as top-six players at their positions, according to PFF. The fifth, Isaac Seumalo, ranked 19th among guards. The changes shouldn't cause you to stray from the Eagles' skill-position players in fantasy. With better injury luck at receiver in 2020, this offense is headed for a massive rebound and the line will remain a strength.
8. San Francisco 49ers
Depth: Daniel Brunskill, Ben Garland, Justin Skule, Colton McKivitz (R), Ross Reynolds
Rarely do we see an elite left tackle retire, only for a team to upgrade at the position. That might be the case after Joe Staley called it a career and the 49ers managed to acquire Trent Williams for third- and fifth-round picks. The good teams take advantage when value presents itself and John Lynch and the Niners have earned the right to be mentioned with the NFL's most well-run organizations.
We all know Kyle Shanahan's rushing attacks are regularly among the league's best. If you're searching for evidence to prove the success of his system and offensive line, look no further than the three consecutive finishes inside the top-10 of Football Outsiders' run-blocking rankings. They also made life especially easy on their ball carriers in 2019 by helping Raheem Mostert (second), Matt Breida (third), and Tevin Coleman (10th) finish among the top-10 players in rushing yards before contact per attempt, according to Pro Football Reference.
If you take one thing away from this section, it's to invest in the 49ers backfield for as long as Shanahan is their head coach because we know any back on the depth chart can emerge as a fantasy starter. That means jump on Mostert and Coleman, as well as Jerick McKinnon and JaMycal Hasty. You should even keep Jeff Wilson and Salvon Ahmed on your watchlist.
Legendary offensive line coach Dante Scarnecchia retired this offseason, which hurts the current performance and future development of the Patriots' offensive linemen. His departure will be mitigated by the healthy returns of Isaiah Wynn and David Andrews. Wynn has only appeared in eight games since being selected in the first round of the 2018 NFL Draft. Andrews dealt with blood clots that sidelined him last year, putting him in a high-risk category if he were to contract COVID-19.
Yodny Cajuste, another player who missed last season due to injury, is the favorite to slide in at right tackle after Marcus Cannon opted out. Cajuste, entering his second year, is a wild card on the outside - a scary proposition when your new starting quarterback has durability concerns.
There's a good reason Joe Thuney will be playing under the franchise tag. He's been New England's best blocker for the last couple of seasons and is making a case as one of the better players at his position. The same can be said for Shaq Mason. Both guards earned top-10 grades from PFF in 2019.
David DeCastro and Maurkice Pouncey are the stalwart stars of this Steelers front with 13 Pro Bowls and four first-team All-Pro honors between them. Alejandro Villanueva is doing his best to catch up, having reached the Pro Bowl in two of the last three seasons. That trio will be counted on more than ever as some rare roster shuffling takes place around them.
Pittsburgh's line, which has enjoyed immense continuity over the years, will field two new starters in 2020. Matt Feiler is expected to move from right tackle to left guard, setting up a training camp competition on the right side between Chukwuma Okorafor and Zach Banner. They'll benefit from playing next to DeCastro, but this creates a potential weakness in a unit that's been impervious for a while now.
Regardless of who wins the job, all five starters should be prepared to pass block more with Ben Roethlisberger back under center. It's easy to forget after his elbow surgery, but Big Ben is just one year removed from leading the league in passing attempts. Though the improved defense will likely prevent them from needing to take to the air that much, we're sure to see fireworks return this season. If Roethlisberger stays healthy, the Steelers' passing weapons will be outstanding values in fantasy drafts.
5. Las Vegas Raiders
Depth: Brandon Parker, David Sharpe, John Simpson (R), Denzelle Good, Andre James
The Raiders are bringing back the same starting five from last season and it's a group made up of average to above-average linemen. In 2019, Rodney Hudson was an All-Pro, Trent Brown a Pro Bowler, and Richie Incognito came close to recapturing his pre-retirement form. Gabe Jackson might be a better pass-blocker than a run-blocker, but he's far from a liability.
After struggling as a rookie, former first-round pick Kolton Miller gained weight and confidence heading into his sophomore season and it showed. While he didn't attain superstar status, Miller rose from a bottom-of-the-barrel performer in 2018 to a middle-of-the-pack tackle as a sophomore. That's enough to instill hope he can continue to develop his game in his third year.
With continuity on their side, the Raiders are getting overlooked when discussing the NFL's best offensive lines in a year with no preseason games and limited prep time. Running back Josh Jacobs finished second in PFF's elusive rating as a rookie while battling a shoulder injury for part of last season. It would not be shocking to see him lead the league in rushing behind this line in 2020. Another item working in Jacobs' favor is the signing of veteran tight end Jason Witten.
4. Baltimore Ravens
Orlando Brown Jr.
Depth: D.J. Fluker, Tyre Phillips (R), Ben Bredeson (R), Will Holden, Patrick Mekari
Marshal Yanda's retirement isn't being talked about enough when it comes to the Ravens' offense and specifically their blocking. The Ravens were third in Football Outsiders' adjusted line yards and third in adjusted sack rate with Yanda in the lineup in 2019. Replacing one of the best guards to ever play professional football is no simple task. The main names battling for the job - Ben Powers, D.J. Fluker, and Tyre Phillips - represent serious downgrades at the position.
There's enough talent in Baltimore to pick up the slack and keep this line among the top five. Left tackle Ronnie Stanley has emerged as a powerhouse and earned the highest pass-blocking grade ever bestowed by PFF. Orlando Brown Jr. and Bradley Bozeman have become solid starters the Ravens found in the third- and sixth-rounds of the 2018 draft. Matt Skura was playing very well before going down with an ACL tear and a dislocated knee cap.
Lamar Jackson's ability to spread defenses out and force them to second guess their decision-making gives his blockers an advantage. Their symbiotic relationship was well designed by the Ravens' coaching staff and the line's versatility allows them to mix zone spread schemes with power concepts. In short, until further notice, draft Ravens players at will in fantasy.
The Cowboys have been among the top-three offensive lines for several seasons. While losing Travis Frederick to retirement hurts, they're deep enough to maintain their elite position. Zack Martin, Tyron Smith, and La'el Collins are all dominant blockers in their own right - despite being at different stages of their careers. The unit will be capable of handling any defensive front it faces if it can stay healthy.
It was Joe Looney who stepped in at center when Frederick was diagnosed with Guillain-Barre syndrome and sat out the entire 2018 campaign. Looney will likely be called upon to do so again, but fourth-round rookie Tyler Biadasz could challenge him.
There aren't many weaknesses across the board on the Cowboys' offensive depth chart. With Dallas' line coming off its seventh straight appearance in the top 10 for adjusted line yards, we can feel confident in the fantasy outlooks for all the Cowboys' skill-position stars. Ezekiel Elliott doesn't get much consideration for the first overall pick in fantasy drafts, but he belongs in that conversation with this line in front of him.
2. New Orleans Saints
Cesar Ruiz (R)
Depth: Nick Easton, James Hurst, Will Clapp, Ethan Greenidge, Patrick Omaneh
Terron Armstead was in the lineup for all but one contest in 2019 after missing 21 games due to injury over the previous three seasons. He's one of the best linemen in the game, but there could be a debate whether he's even the best tackle on the Saints. That's not to disparage Armstead in any way, but rather acknowledge how far right tackle Ryan Ramczyk has come. The 26-year-old Ramczyk graded out as PFF's No. 1 tackle in the league last season, with his 29-year-old teammate finishing ninth.
New Orleans' embarrassment of riches doesn't end there. Losing players like Max Unger and Larry Warford over the last two seasons amounted to speed bumps on its depth chart. The team was able to restock the roster with impactful young talents like Erik McCoy and Cesar Ruiz. The Saints will push for the top spot on this list if Ruiz steps in right away and Andrus Peat rediscovers his early-career success.
The offensive line's quality has certainly helped extend Drew Brees' career and likely factored into the 41-year-old's decision to put off retirement. That's great news for fantasy owners, who have even more weapons to choose from in New Orleans this year with veteran Emmanuel Sanders added to the roster.
Deciding between the Colts and Saints was difficult. Indy gets the nod, though, thanks to its continuity by returning all five starters. Much like in New Orleans, the Colts' front office had consistent success building their line through the draft. Anthony Castonzo, Quenton Nelson, and Ryan Kelly were former first-rounders, while Braden Smith was chosen early in the second. All four players graded out in the top 12 at their positions last season and three of them are 27 years old or younger, so you can expect this level of dominance to continue for several years.
Marlon Mack isn't an elite ball carrier, but he was able to eclipse 1,000 yards behind this line in 2019. What do you think will happen when you pair second-round pick Jonathan Taylor - the best pure runner in this year's draft class - with this commanding front? The answer is fantasy championships. Make sure you're targeting Taylor as a potential breakout star in 2020.
Philip Rivers may find a similar fountain of youth in Indianapolis, the same way Brees has been able to extend his career in New Orleans. The former Charger appeared to be nearing the end last season as his arm struggled to make downfield throws that were once routine for him. Perhaps, some of the blame can fall on the Chargers' blocking. With a full complement of pass-catching weapons and the best line in the business, the 38-year-old may surprise fantasy owners.
