PFSN’s player Offensive Line Impact (OLi) assigns a numerical score and a letter grade to an individual offensive lineman's performance. The grade is split 60/40 between pass blocking metrics and run blocking metrics. While linemen are ranked together as a unit, we also listed where each Tackle, Guard, and Center ranks among his position subgroup as well.

To qualify for the rankings, a player must play at least 25 snaps per team game for the season, or 25 snaps in any given game for the game rankings. His position subgroup is based on the position where he played the most snaps in that given game or season.
