Seattle’s backfield remains one of the most frustrating committees in the league as Kenneth Walker III and Zach Charbonnet continue splitting work without defined roles. Both runners enter Week 10 with concerning usage patterns and production metrics that create weekly headaches for fantasy managers. Can fantasy football managers trust either Seahawks runner against the Arizona Cardinals this week?
Kenneth Walker III Fantasy Outlook
Just when fantasy managers thought they understood this backfield, Seattle flipped the script entirely. For the first time all season in a game where Charbonnet was active, Walker eclipsed a 50% snap share against Washington. The Michigan State product played the majority of snaps while serving as the clear lead back throughout the contest.​
The blowout nature limited Walker’s overall opportunities despite his expanded role. Sam Darnold threw four first-half touchdowns and the Commanders were never competitive, leading to starters sitting the fourth quarter. Walker handled 11 carries and two targets in the victory, modest volume that reflected game flow rather than reduced involvement.​

The most notable change occurred near the goal line, where Walker received carries for the first time all season. This had been Charbonnet’s exclusive domain through the first eight weeks, but Seattle handed Walker the chance to punch it in. Naturally, Walker was unable to convert any of those chances, leaving fantasy managers and coaching staff questioning the decision.
Given Walker’s failure to capitalize on goal-line opportunities, expect Charbonnet to likely return to that role this week. However, the fact that Seattle even experimented with Walker near the end zone means it’s no longer a certainty that he won’t receive future goal-line work. This development adds another layer of unpredictability to an already frustrating committee situation.
Zach Charbonnet Fantasy Outlook
Last week marked Charbonnet’s lowest involvement of the season by a significant margin. He played just 35% of snaps, well below his typical workload and representing a dramatic shift from previous weeks. Charbonnet handled only eight carries and ran just six routes, both season lows by far.​
The reduced playing time stems partly from game script but also reflects Seattle’s apparent desire to give Walker expanded opportunities. With a 4.3% target share and now sharing early-down work more evenly, Charbonnet has become almost entirely dependent on touchdowns for fantasy relevance. His path to double-digit fantasy points requires finding the end zone.
The loss of goal-line exclusivity represents a concerning development for Charbonnet’s fantasy value. While he remains the favorite to handle short-yardage situations based on his success throughout the season, Walker’s usage near the goal line last week creates uncertainty. Touchdown equity was Charbonnet’s primary advantage over his backfield partner.
Efficiency continues plaguing Charbonnet just as severely as Walker. Both backs remain completely ineffective as rushers, with Charbonnet’s 2.9 yards per carry ranking among the worst in the league. Despite what their talent profiles might suggest, this is easily one of the worst backfields in the NFL from a pure production standpoint.
Should You Start Walker or Charbonnet This Week?
Arizona presents a difficult matchup for both Seattle running backs in this Week 10 rematch. The Cardinals allow the 12th-fewest schedule-adjusted fantasy points per game to running backs, creating challenging conditions for an already struggling committee. Arizona also surrenders only 11.2% of their total receiving yards to the position, further limiting upside for pass-catching backs.
The previous meeting between these teams provides some context. Walker posted one of his better performances with 110 yards from scrimmage in that contest. Charbonnet managed just 44 yards but found the end zone, demonstrating both backs can contribute when opportunities arise. However, Arizona’s defense has remained stout against the run throughout the season.
Seattle’s commitment to running the football persists despite having superior options in the passing game. The Seahawks’ 49% neutral game script run rate ranks sixth-highest in the league, meaning they continue leaning on the ground attack even when throwing to Jaxon Smith-Njigba is clearly their best and most efficient way to move the ball. This philosophical approach keeps both backs involved but limits overall offensive efficiency.
Walker and Charbonnet seemingly lack defined roles at this point, alternating drives and snaps almost at random. Charbonnet remains the favorite to handle goal-line work based on season-long trends, but it’s no longer the certainty it once was after last week’s usage. Both backs qualify as nothing more than RB3 plays in this difficult matchup, suitable only for fantasy managers facing desperate roster situations from byes or injuries.
