Get ready for your season with theScore's 2017 Fantasy Football Draft Kit
Depth: Jordan Mills, Michael Ola, Vladimir Ducasse, Ryan Groy, Seantrel Henderson (susp.)
Buffalo returns the entire group that paved the way for the NFL's top-ranked rushing attack last season. There's even a path to improvement with Dawkins, a second-round rookie, presumably pushing Mills for the starting right tackle job.
Depth: Wes Schweitzer, Ben Garland, Kevin Graf, Andreas Knappe
Mack's arrival last offseason helped solidify the Falcons' line and was a big reason why their offense reached new heights, including an MVP award for Matt Ryan and an appearance in Super Bowl LI. Even with offensive coordinator Kyle Shanahan gone, Devonta Freeman and Tevin Coleman will have plenty of room to run behind this unit.
Depth: Jason Spriggs, Don Barclay, Kyle Murphy, Kofi Amichia
Green Bay's interior offensive line has taken hits in consecutive offseasons, this time losing T.J. Lang to the division-rival Lions in free agency. That's less concerning considering how good the tackles still are - Bakhtiari and Bulaga may be the best tandem of pass protectors in the business.
Depth: Arie Kouandjio, Ty Nsekhe, Chase Roullier, Vinston Painter
It may be a surprise to see the Redskins this high on the list, but Washington's line features arguably the best left tackle in the game and two high-quality starters on the right side. Long held his own at center in 2016, leaving left guard as the only true weak spot. Kirk Cousins has overachieved thanks to the talented group around him, and the offensive line is a big part of that.
Depth: Cameron Erving, Spencer Drango, Roderick Johnson, Marcus Martin, John Greco
No team made more significant upgrades to its offensive line than Cleveland. Landing Zeitler and Tretter in free agency helps establish this area as a foundation of the rebuilding roster, and that only means good things for Isaiah Crowell and Co. this season.
Depth: Sebastian Tretola, Dennis Kelly, Tim Lelito, Corey Levin, Brad Seaton
The Titans' decision to invest in the offensive line has paid off with a pair of stud tackles anchoring the outside and an interior trio that's emerged as a consistent force. As long as Lewan doesn't get suspended for any boneheaded behavior after the whistle, this line will continue to pave the way for the Titans' offensive players to be fantasy stars.
Depth: Jerald Hawkins, Chris Hubbard, B.J. Finney, Matt Feiler
Ben Roethlisberger gets a lot of credit for his ability to work through traffic in the pocket, and deservedly so. But that shouldn't take anything away from how good this five-man front continues to be. The balance and consistency throughout Pittsburgh's offensive line makes up for any lack of star power.
Depth: Stefen Wisniewski, Halapoulivaati Vaitai, Chance Warmack, Matt Tobin
Once Johnson came back from his 10-game suspension, the Eagles' line returned to its elite form, and should remain that way in 2017. With the new skill-position weapons added in the offseason, Philadelphia's offense could surprise, as a rarely disrupted Carson Wentz is able to settle in and make plays downfield.
Depth: Jonathan Cooper, Emmett Cleary, Joe Looney, Byron Bell
There's relative uncertainty at left guard and right tackle, but the staggering level of talent at the other three positions will almost certainly mask issues. A trio of perennial All-Pros playing on the same offensive line is just unfair. Dak Prescott and Ezekiel Elliott continue to have it made for the foreseeable future.
Depth: Austin Howard, David Sharpe, Vadal Alexander, Denver Kirkland, Jon Feliciano
There's only one line capable of unseating the Cowboys at the top of the list and it resides in Oakland ... for the time being. Offensive linemen rarely get their due, but Osemele is one of the best players in the NFL. The fact he's surrounded by Penn, Hudson, and Jackson is a testament to the excellent work of the Raiders' front office over the last few years. It's also worth noting the importance of the center position, as most of the league's premier protection units feature stars in the middle. Even if Marshawn Lynch has lost a step, it's easy to imagine him gaining yards behind this outstanding collection of blocking talent.
