The bull case for Jaylen Warren in 2026 is straightforward and well-earned. He is Pittsburgh's listed RB1 on the first depth chart of the regular season. He is coming off a career year: 211 carries for 958 rushing yards, 333 receiving yards, 40 catches on 45 targets, and 8 total touchdowns, a mark that tied Kenny Gainwell for the team lead. That production made him RB17 in PPR scoring in 2025. He re-signed with Pittsburgh on a second contract this offseason, which reads as the team committing to him as part of its long-term plan. He also reported slimming down over the offseason, saying he feels faster and more explosive. Add in that Najee Harris left in free agency, clearing a large chunk of carries and goal-line work, and the case writes itself: a proven, improving back stepping into a vacated lead role.
That case is not built on hope. It is built on real 2025 production and a real 2026 depth-chart designation. A reader who takes Warren as a confident top-24 back this year is not being irrational. The question is whether the environment around him actually supports the workhorse volume that top-24 finishes usually require, or whether it only supports a good committee season that caps out short of that mark.
The Backfield Pittsburgh Actually Built
Start with who else is in that room. Rico Dowdle signed with Pittsburgh as a free agent in March 2026 and is expected to share the backfield with Warren, not simply back him up. Travis Homer was also added as a free-agent running back that same month, a depth and special-teams move rather than a threat to Warren's snaps, but it still adds another body to a room the team is not treating as thin at the top. Kaleb Johnson factors into the committee picture as well, per reporting on the backfield setup. Warren himself does not describe this as his job to lose. Asked about his role on September 7, he said: "I don't see a difference in my role. Just go out there, ball. We don't know the rotation yet. But we know what it is in the running back room. We're both gonna be playing a significant amount. It's exciting." That is not the language of a player who expects to see 20-plus touches most weeks. It is the language of a back who expects to split work and is comfortable with it.
Layer in the coaching change. Mike McCarthy is the new head coach, and the offense now runs under his staff rather than the Arthur Smith setup that governed 2025's run-heavy, committee-based usage. Aaron Rodgers is the expected 2026 starting quarterback, a change from the prior season. New play-caller, new quarterback, and a backfield the team itself has described as a "1-2 punch" rather than a bell-cow situation. None of that is disqualifying for Warren, but none of it is evidence that Pittsburgh is planning to hand him a true workhorse share, either. The consensus bullish take is pricing in the depth-chart label and the departed competition. It is not fully pricing in the fact that the team replaced Najee Harris's departure with another proven back rather than leaving the job open.
A Depth Chart Title That Split Its Own Reps
The RB1 designation matters, but it arrived after a summer in which Warren and Dowdle split first-team work. That detail undercuts the idea that the depth chart reflects a clear hierarchy rather than a naming formality ahead of Week 1. A Steelers Depot report from September 7 framed the real uncertainty plainly, noting that "the only real concern entering the regular season is that the Steelers haven't seen much of them on the field so far." That is a statement about how little clarity actually exists on usage, not a statement about Warren having pulled away. A back who is truly locked into a workhorse role rarely needs that kind of hedge from the coverage tracking him closely.
The Market Already Knows This
If the bullish case were fully sound, the market would be pricing Warren like a clear-cut RB2 with upside toward RB1 numbers. It isn't. Warren's ADP is 27th overall among backs, and his ESPN PPR ranking as of September 8 was RB27. Dowdle sits close behind at 29th overall. Those numbers describe two backs the market expects to split value, not one lead back and a clear backup. A market that liked Warren as a true workhorse would have priced him closer to the RB15-20 range on the strength of his 2025 production and the vacated Harris touches. Instead it landed him just outside the RB24 cutoff the claim here is built around, which suggests drafters are already discounting the committee risk even while treating him as the headline name in the room.
What Would Still Have to Break Warren's Way
The honest counter to all of this is real. Warren just posted 958 rushing yards, 333 receiving yards, and 8 total touchdowns, and the Steelers have now put him atop the depth chart to start the year. If Dowdle underperforms early, or if Pittsburgh's staff decides Warren's receiving work is too valuable to ration, the touch share could tilt hard enough to produce a top-24 season anyway. Warren's own comments suggest he is not fighting the committee framing, which could mean he is simply being modest rather than accurately describing a shrinking role. There is also a residual injury concern working against him: he has missed four games across his four NFL seasons, which matters more for a back who needs volume than for one with a clear receiving or goal-line monopoly to fall back on when touches dip.
None of that changes the baseline picture. It just means the range of outcomes is wide, and the top of that range still requires the exact kind of workhorse usage that neither the coaching change, the backfield additions, nor Warren's own words are currently describing.
The claim this evidence supports is narrower than a bust call and more specific than generic committee caution: Warren finishes outside the top-24 PPR running backs in 2026 because Pittsburgh built a genuine two-man committee with Dowdle, added further depth in Homer, and is running that plan under a new coaching staff that has given no signal it intends to feed one back a workhorse share. Treat him as a flex-caliber option with real upside if the committee tilts his way, not a locked top-24 asset on draft day.
