The Cowboys offensive line took a step back last season after fielding what was arguably the league’s top line in 2019. Not much has changed for a good-looking group entering 2021, though the center position is still a hole that needs to be filled following Travis Frederick’s retirement. Like the Philadelphia Eagles, the Cowboys are banking on health in 2021 as Zack Martin, La’el Collins, and Tyron Smith return to play alongside Connor Williams.
The Packers return four of five offensive line starters and could still re-sign Ricky Wagner, which would return 86-percent of their snaps from last season. However they did lose all-pro center Corey Linsley, who has graded as PFF’s No. 6, No. 7, and No. 1 center over the last three seasons, in free agency. While losing Linsley will hurt, there is still enough talent along this offensive line to remain a top unit in 2021.
