he biggest surprise from the Steelers‘ first unofficial depth chart of the 2025 NFL season is the unexpected ranking of rookie running back Kaleb Johnson as the third-string running back, behind Jaylen Warren and Kenneth Gainwell. This placement defied many preseason expectations, as Johnson had shown promising flashes during training camp and was widely anticipated to contend more closely for the starting role.

Kaleb Johnson, a 2025 NFL Draft pick, entered Steelers training camp with considerable buzz thanks to his impressive speed and burst, attributes that the Steelers have lacked at the running back position in recent seasons. Early practice reports highlighted his patience and ability to produce good plays, raising hopes that he might secure a starting-back role alongside Jaylen Warren. However, the initial depth chart listing him as RB3 signals a more cautious approach by the Steelers’ coaching staff, especially head coach Mike Tomlin, who appears to want Johnson to improve his pass protection before entrusting him with a bigger workload. That Kenneth Gainwell, a veteran signing mainly valued for his kick return skills, currently occupies the RB2 slot ahead of Johnson adds to the surprise. Gainwell’s depth chart position suggests the Steelers may prioritize experience and reliability, at least initially, over raw rookie talent in the backfield.

Kaleb Johnson has been described as “inhumane” at camp.

This designation is a clear signal that while Johnson’s physical tools are impressive, he needs to refine some aspects of his game under NFL conditions, particularly in pass protection, an area that coaches often emphasize for running backs to remain on the field in diverse situations. The setback is not definitive but underscores the Steelers’ measured developmental approach. Johnson is expected to continue his strong camp performances with aims to ascend the depth chart before the regular season kicks off or shortly thereafter.
While Johnson’s depth chart positioning is surprising and somewhat disappointing for fans expecting a rapid rise, the Steelers’ decision to slot rookie defensive end Derrick Harmon directly into a starting role is equally notable—but for the opposite reason. Harmon, a first-round pick, has earned immediate starting responsibilities at defensive end1 (DE1), signaling that the Steelers see him as a professional-ready impact player from day one. This contrasts sharply with the more cautious development plan for Johnson.
