Pittsburgh’s backfield continues operating as a committee with both backs receiving meaningful opportunities. Jaylen Warren and Kenneth Gainwell head into a challenging road environment seeking fantasy production. Which Steelers running back deserves roster consideration for fantasy football managers navigating Week 16 lineups?
Jaylen Warren’s Fantasy Outlook
Warren continues starting and serving as the lead back, but his stranglehold on RB1 duties has dissipated over recent weeks. He hasn’t hit a 60% snap share since Week 8, signaling a more balanced approach from the coaching staff. The veteran back saw 15 opportunities last week in positive game script, marking his highest workload in a month.​
The volume provides a foundation for fantasy relevance, but efficiency concerns persist. Warren continues struggling with rushing effectiveness, limiting his ability to maximize the touches he receives. His role as the nominal starter guarantees him first crack at early-down work, though the snap distribution no longer reflects traditional lead-back usage patterns.​

Warren remains viable as a touchdown-dependent option whose value hinges on finding the end zone rather than accumulating yardage. The reduced snap share caps his weekly floor significantly compared to earlier in the season when he commanded a more dominant role. His fantasy managers need realistic expectations about his ceiling given the efficiency struggles and committee structure.​
Kenneth Gainwell’s Fantasy Outlook
Gainwell has maintained a snap share around 50% for most of the season, establishing himself as a legitimate complement rather than a pure backup. He significantly out-touched and outplayed Warren last week, carrying the ball 13 times for 80 yards while adding seven receptions on seven targets for 46 yards. The dual-threat production showcased his expanded role in Pittsburgh’s offensive scheme.​
The receiving workload has become particularly impressive recently. Gainwell has caught at least six passes in four of his last five games, providing a reliable PPR floor that Warren cannot match. This consistent pass-catching involvement creates weekly fantasy relevance regardless of rushing volume or game script.​

His efficiency advantages over Warren have become increasingly apparent. The 80 rushing yards on 13 carries represented strong production that highlighted his superior vision and explosiveness when given opportunities. Gainwell’s ability to contribute meaningfully in both phases makes him the more dynamic threat between the two backs.
Should You Start Warren or Gainwell This Week?
Detroit presents a challenging defensive matchup that undoubtedly favors Gainwell’s skill set. The Lions function as a pass-funnel defense. They allow the third-fewest schedule-adjusted fantasy points per game to running backs. However, they allow the second-most schedule-adjusted fantasy points per game to wide receivers, forcing opponents to attack through the air rather than on the ground.​​
The Steelers enter as touchdown underdogs in a game that projects favorably for Detroit’s offense. Pittsburgh faces a 6.5-point spread with the total set at 51.5 points, suggesting a competitive but Lions-favored contest. The Lions average nearly 40 points per game coming off losses, and they lost last week to the Rams. Detroit will score points and force the Steelers to throw more than they prefer.​​
An interesting wrinkle further complicates the matchup for traditional rushing backs. The Lions have been the best team in the league at stopping pass-catching backs, with a league-low 8.6% of their total receiving yards allowed going to running backs. Part of the reason stems from how poorly they defend the pass overall. Teams can throw to their receivers successfully and don’t need to check the ball down to backs.​​
Nevertheless, Gainwell has seen deliberate usage in the passing game throughout the past month. His role reflects offensive design rather than circumstantial opportunity, making him less dependent on defensive tendencies. Even in this tough matchup, he shapes up as the preferred option between the two backs.​
Warren profiles as a touchdown-or-bust RB3 whose weekly ceiling depends entirely on finding the end zone in short-yardage situations. Gainwell represents the superior fantasy start this week given his receiving role and efficiency advantages despite the challenging defensive environment.​
