Though the team seems to be system-agnostic when running their offense, the Lions have been highly gap-heavy this year and have focused on pushing the ball down the field through their running backs. Detroit is second in the league with their 372 yards on the ground and is eleventh in the league with 84 receiving yards to the RB position. D'Andre Swift (RB3) and Jamaal Williams (RB19) have performed as top-20 options at this point in the season.
Per the article, the Lions are first in yards per carry (7.15), third in explosive runs (seven), and also second in EPA per rush and rushing DVOA, Football Outsiders’ opponent-adjusted efficiency metric. What's scary for opposing defenses; they've accomplished all of this while dealing with a slew of offensive line injuries. They may just be getting started.
