Fantasy Impact: Phillip Rivers' arrival in Indianapolis finally gifts him the luxury of an elite offensive line. The 39-year-old veteran never boasted mobility as one of his top traits, but standouts Quenton Nelson, Branden Smith and Anthony Castonzo should provide more than enough stability to keep him consistently upright. This Colts unit has a tremendous floor and a ceiling, being the team's top protective front, and returning all five starters for 2020 should serve to minimize any early-season hiccups. Plus, new top RB Jonathan Taylor gets the benefit of tremendous run blocking.

Fantasy Impact: Boasting what's arguably the best tackle duo in the league - Terron Armstead and Ryan Ramczyk - the Saints could probably get away with substandard play on the interior line. However, they've instead been gifted with solid starters all around, with 2019 second-round pick Erik McCoy proving to be a reliable starting center during his rookie season. LG Andrus Peat re-signed long term, positioning the team to return four of five starters along the O-line. First-round rookie Cesar Ruiz enters the season as the only question mark among what was one of the few elite groups in the league last year.

Starters: Ronnie Stanley (LT), Bradley Bozeman (LG), Matt Skura (C), Tyre Phillips (RG), Orlando Brown (RT)

Injuries: Tyre Phillips (hand)

Backups: (T): Tyre Phillips (G): Ben Powers (C): Patrick Mekari

Fantasy Impact: Though it's true that a quarterback with elite mobility and elusiveness makes the O-line's job drastically easier, Baltimore's group boasts reliable pass- and run-blocking skills by any measure. Replacing long-time standout Marshal Yanda is a tall task, and though a competent RG could emerge from the combination of D.J. Fulker, Ben Powers and Ben Bredeson, the position has seen a slight downgrade. The presence of Ronnie Stanley, one of the best LTs in the league, and an above-average starter in Orlando Brown Jr. bookending the right side, has helped to further ease that transition.

Starters: David Bakhtiari (LT), Elgton Jenkins (LG), Corey Linsley (C), Lucas Patrick (RG), Billy Turner (RT)

Injuries: David Bakhtiari (chest), Corey Linsley (back), Lane Taylor (knee, IR), Simon Stepaniak (knee. NFI)

Backups: (T): Yosh Nijman, Rick Wagner (G): Jon Runyan, Elgton Jenkins (C): Lucas Patrick

Fantasy Impact: Having a left tackle with a strong case to be considered the best in the league at his position, such as David Bakhtiari, can serve to elevate the play of an entire offensive line. Such is the case in Green Bay, where concerns linger around most other spots on the O-line, save standout C Corey Linsley. Rick Wagner is hoping to bounce back from the worst campaign of his career and replace Bryan Bulaga at RT, LG Elgton Jenkins is looking to build off a solid rookie year, and Billy Turner's ceiling at this point may be that of a league-average starter. However, Losing RG Lane Taylor (knee) to a season-ending injury Week 1 has the potential to limit this unit's upside all year, unless Lucas Patrick can quickly transition into a reliable starter.
