In the ever-changing landscape of fantasy football, running backs are central to a team's success. As the season progresses, some running backs have seen their roles shift, while others have maintained their value. Let's take a closer look at several key players and their fantasy outlook for the upcoming week.

Rhamondre Stevenson, the New England Patriots' running back, has faced a frustrating season so far. Once a top performer last year, he has seen his rushing opportunities decrease, with Ezekiel Elliott taking on a more prominent role. However, Stevenson's involvement in the passing game offers some hope, with solid reception and yardage numbers. While not the workhorse back fans had hoped for, Stevenson still holds RB2-level value.

James Cook of the Buffalo Bills had a quiet week against the Bengals, but his consistent involvement in the offense, averaging around 14 touches per game, highlights his importance. Questions loom regarding Cook's role once Leonard Fournette settles in with the Bills, but this week's matchup against Denver is not expected to sideline Cook entirely.

Following Cam Akers' season-ending injury, Alexander Mattison has become the Minnesota Vikings' lead running back. While he lacks efficiency as a runner and hasn't scored a rushing touchdown this season, Mattison's pass-catching abilities have boosted his fantasy value. The addition of new quarterback Josh Dobbs raises some uncertainty, but it also opens up possibilities for Mattison's rushing efficiency and touchdown potential.

Najee Harris of the Pittsburgh Steelers has bounced back recently, ranking as RB18 in fantasy points per game since the team's bye week. He has regained the trust of fantasy managers and should be considered a reliable option. Additionally, Jaylen Warren has emerged as a decent play alongside Harris, consistently showcasing his pass-catching skills and averaging a solid 4.7 yards per carry.

Zach Charbonnet's increased playing time for the Seattle Seahawks raises questions about a potential backfield split. While Kenneth Walker remains the lead running back, Charbonnet's impressive performance has earned him opportunities. Seahawks head coach Pete Carroll's meritocracy approach ensures that Charbonnet will continue to be involved. For now, Walker holds a higher ranking, but Charbonnet cannot be overlooked.

Tyjae Spears, a supporting player for the Seahawks, has shown promise but lacks the opportunities of his teammate Jaylen Warren. With a tough matchup against the Buccaneers, Spears may not be an appealing option for fantasy lineups this week.

Finally, Keaton Mitchell presents a range of possibilities in the Baltimore Ravens' backfield. Whether he remains third in the pecking order behind Gus Edwards and Justice Hill, creates a three-way split, or supplants Hill as the lightning to Edwards' thunder remains to be seen. While a breakout performance similar to Chris Johnson's is a longshot, Mitchell's ranking as RB44 suggests caution for fantasy managers.

As fantasy football owners navigate through their lineup decisions, weighing the roles and potential of these running backs is crucial. Paying attention to the latest updates and developments will be key in gaining that coveted competitive edge in the world of fantasy football.
