Few things are more important to a team’s success than the quality of its offensive line. Disastrous lines, or even disastrous weak-link mismatches, can determine the outcome of games, while strong units provide an incredible advantage to an offense.

We will be monitoring NFL offensive line play all season long while highlighting the biggest weak-link players for each group. With Week 4 of the 2023 NFL regular season in the books, here are the weekly rankings and each unit's best player.

• Nelson’s roller-coaster season continues, as he earned his highest overall grade this season while recording his lowest pass-blocking grade of the campaign. This was due to him grading out at 78.5 in run blocking, his best mark of 2023.
