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

Below, you can find full team-by-team data on snap counts, target share, routes run, red-zone usage and more for every Fantasy relevant running back. Check back later in the week for What We Learned, where Gibbs will break down all the takeaways you should have from Week 4, pulling largely from the information here and in his usage report for wide receivers and tight ends. 

If you have questions about any stats, players, or situations covered or not covered in this article, feel free to reach out to Gibbs on Twitter.

Week 4 Leaders

No stat correlates more closely with Fantasy scoring at the RB position than snap 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 all have run a route on at least 59 percent 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.

When allowed to run routes, the above running backs have been targeted at the highest rate. For reference, James White led the position with a 35 percent TPRR rate in 2020, and only three backs were targeted on more than 30 percent of their routes. Cordarelle Patterson's rate is nearly guaranteed to come down.

Targets are essential in accessing top-end Fantasy RB upside, so it is exciting when teams go out of their way to find creative ways to get their backs involved in the passing game.

The Rams got right back to feeding Darrell Henderson one of the best roles of any RB in the entire NFL in his first game back from injury. Also worth noting: the Dolphins continue to move away from Myles Gaskin and toward Malcolm Brown; that preference has been made especially clear when in the red zone.

So which running backs were leaned on in the red zone in Week 4? And what do you need to know about how every running back was used in the passing game this past week? ...
