Fantasy Impact: Phillip Rivers' arrival in Indianapolis will finally gift him the luxury of an elite offensive line. Rivers, who is now entering his age-39 season, 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 outright. The Colts' unit has a tremendous floor and a ceiling of being the team's top protective front.

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. With left guard Andrus Peat re-signed long term and right guard Larry Warford still under contract, the Saints are poised to return all five starters on a unit that was one of the league's best in 2019.

Fantasy Impact: Despite continuously boasting a top-10 offensive line in recent years, the Eagles have refused to rest on their laurels. Instead, the team invested a 2019 first-round pick in LT Andre Dillard, who saw mixed results as an injury fill-in during his rookie campaign but apparently showed enough for the Eagles to move on from future Hall of Famer Jason Peters. It may be a downgrade on the blindside, but the other four spots on the line remain stellar.

Fantasy Impact: The Cowboys tried to avoid attrition to the offensive front, but their plan was ruined when star center Travis Frederick decided to retire. The team still has a trio of standout blockers in Tyron Smith, Zack Martin and La'El Collins, but the center and left guard spots appear far les stables, especially with 2018 second-round pick Connor Williams rehabbing from the torn ACL he suffered on Thanksgiving.
