After looking at the offseason in it’s entirety, I’ve come to the conclusion that the Los Angeles Rams have taken a serious interest and intrigue into improving the run defense.
In 2018, the Rams allowed 116.3 rushing yards per game (18th in the league) and 4.8 yards-per-carry (27th in the league). The first value (YPG) isn’t terrible per se, but it’s also not extremely valuable because of how potent the Rams’ offense was. When a team is consistently behind by two or three scores, they’ll obviously abandon the run and that’s why the YPC metric is more appropriate when evaluating a run defense (with other stats to boot).
