Also notable: Rookie RB Kaleb Johnson is listed as the team’s RB3 behind Warren and Kenneth Gainwell, a Mike Tomlin favorite. Johnson, the 83rd pick in the 2025 NFL Draft, had been listed as a co-starter alongside Warren in the spring. He’s struggled mightily in training camp, particularly in pass protection, where Warren has always excelled. The big-bodied Johnson could still take on short yardage and even goal line opportunities in what should be a run-heavy Pittsburgh offense. It looks like Warren has a chance to establish himself as the team’s clear lead back headed into the season. Warren could benefit from Aaron Rodgers’ late-career willingness to check down. Last season, Jets running backs had the league’s fourth highest target share with Rodgers under center.
