The offense of the Washington Commanders has been on fire, leading the league in points scored, points per game, scoring margin, and advanced metrics like EPA per play.
The defense has struggled more, currently ranking 18th in rushing yards allowed per game, 16th in total yards per game, and 15th in points per game given up. Several advanced metrics rank the Washington defense lower; for example, by DVOA, the Commanders rank 23rd (Vikings rank 1st, Jaguars rank last).
Anyone who has watched the Commanders play football for the first 7 weeks of the regular season is likely to feel that the defense has been improving.
