In 2020, the Green Bay Packers offense was the most productive in the NFL, finishing first in points per game and first by DVOA. As is always the case, there are a number of reasons for their success on offense, but a big factor was the play of the offensive line.
Green Bay's offensive line ranked first by ESPN's pass-blocking and run-blocking win rate metrics; they gave up the fewest sacks during the regular season and the second-fewest pressures. Not to mention that they played at this high-level while dealing with several injuries and position changes.
