We learn new information every week as the ever-changing Fantasy landscape at the running back position reshapes itself. There are many specific usage stats that affect a running back's Fantasy projection, and outside of a few players, we see those underlying backfield usage metrics fluctuate throughout the course of a season. And no week presents us with more new information than Week 1.

Each week, SportsLine's Fantasy expert Jacob Gibbs will examine all of this new information and provide a data-driven deep-dive into Sunday's games to offer a better understanding of what we learned and how it will impact the Fantasy outlook of specific teams and players.

Here, we'll look at the leaderboards in several key metrics around running back usage, then share our look as whose stock is rising in falling after this weekend's action. That includes Jets rookie Breece Hall, whose "debut was a mixed bag," according to Gibbs.

Week 1 Leaders

Snap rate

No stat correlates more closely with Fantasy scoring at the RB position than snap rate.

Route involvement rate

A player's route involvement rate simply represents the percentage of the team's total dropbacks on which that player ran a route. So, the running backs listed above ran a route on at least half of their team's dropbacks. Running routes is the first step towards drawing targets, which is key to unlocking Fantasy upside at the RB position.
