Raheem Mostert vs. Sincere McCormick: Who Wins the Raiders’ Backup RB Job?

By Jason Bolton June 27, 2025 07:17

The Las Vegas Raiders’ running back room is shaping up to be one of the more intriguing position battles heading into the 2025 NFL season. With the offseason additions of veteran Raheem Mostert and first-round rookie Ashton Jeanty, alongside returning players like Sincere McCormick and Zamir White, the competition for touches and specifically the backup running back role behind Jeanty is heating up.

Raheem Mostert: Veteran Speed and Experience

Raheem Mostert, 32, arrives in Las Vegas with a reputation as a dynamic, change-of-pace back. After a Pro Bowl season in 2023 with Miami, where he led the league with 21 rushing touchdowns, Mostert’s 2024 campaign was hampered by injuries and reduced production, totaling just 278 rushing yards and two touchdowns. Despite that, the Raiders see him as a valuable addition to improve their league-worst rushing attack, which averaged only 79.8 yards per game last season.

Mostert’s speed, agility, and ability to make defenders miss remain his calling cards. According to ESPN, Mostert’s “speed and jump cuts have not left his game yet,” making him a threat in open space and a useful weapon in the Raiders’ offense. His pass-blocking grade, comparable to McCormick’s, also adds value in protecting quarterback Geno Smith.

Coach Pete Carroll and the Raiders’ front office view Mostert as a reliable veteran presence who can mentor younger backs and provide a spark in short-yardage and passing situations. While he may not be the feature back, Mostert’s experience and skill set position him as a strong candidate for the second spot in the rotation.

Sincere McCormick: The Young, Versatile Contender

Sincere McCormick, 24, represents the youthful upside in the Raiders’ backfield. Before an ankle injury cut short his 2024 season, McCormick showed flashes of promise, rushing for 64 and 78 yards in Weeks 13 and 14, respectively. His physical running style and ability to gain yards after contact made him one of the few bright spots in an otherwise struggling offense.

McCormick’s recovery from injury and offseason development will be critical. He faces stiff competition from Mostert and Zamir White for limited touches behind rookie Jeanty, who is expected to be the lead back. Reports suggest McCormick is currently fourth on the depth chart, behind Jeanty, Mostert, and White, making his roster spot and playing time uncertain.

Despite that, McCormick’s youth and potential make him a player to watch. His versatility as a runner and blocker could earn him situational roles, especially if he impresses during training camp and preseason.

The Rookie Factor: Ashton Jeanty’s Role

The Raiders’ first-round pick Ashton Jeanty looms large over this competition. With his record-setting college production 2,601 rushing yards in a single season and 88 broken tackles Jeanty is expected to be the primary ball carrier. His ability to run between the tackles and break big plays sets a high bar for his backups.

Who Wins the Backup Role?

Mostert’s veteran savvy and proven explosiveness give him an edge as the change-of-pace back. However, McCormick’s youth and physicality offer a different style that could complement Jeanty’s skill set. Ultimately, the decision will come down to health, consistency in practice, and fit within the Raiders’ offensive scheme.

Raiders insider reports indicate that Mostert is currently favored for the second spot, but McCormick’s strong camp performance could shift the depth chart. Zamir White’s injury history and inconsistent production also factor into the equation.

The Raiders’ running back room is a blend of youth, experience, and high draft capital. Raheem Mostert’s speed and veteran presence make him a strong candidate for the backup role, while Sincere McCormick’s potential and physical running style keep him in the mix. With Ashton Jeanty expected to lead the backfield, the battle for touches behind him will be one of the key position competitions to watch as Las Vegas aims to improve its ground game and overall offensive efficiency in 2025.
