What It Means:

Over the past four games, Perkins and Rashad Jennings have essentially split the work. Jennings out-carried the rookie 18-11 last week, but Perkins was able to do far more damage on his runs, totaling 56 yards to Jennings' 38. Perkins clearly brings the offense a bit more life, but head coach Ben McAdoo appears to trust Jennings more.

There are 64 running backs through Week 15 with at least 50 rushing attempts. Perkins has a -0.05 Rushing Net Expected Points (NEP) per attempt, ranking 42nd, and Jennings' -0.13 ranks 54th.
