Despite missing many stars last season, the San Francisco 49ers won 12 games and reached the playoffs' second round. Much credit goes to running back Christian McCaffrey, but unsung heroes also helped. Most return for 2026, joined by promising rookies.

Wide receiver Demarcus Robinson has been a constant for quarterback Brock Purdy amid injuries to Ricky Pearsall and Mike Evans. Robinson shone in the postseason with six catches, 111 yards, and a touchdown. His role may grow if Evans' health remains an issue.

Defensive tackle C.J. West provided a powerful run-stuffing presence in 2025. With West on field, opponents averaged 3.3 yards per carry; without him, 4.7. Coordinator Raheem Morris praised West's ability, and his return from a concussion boosts the defense.

Safety Ji'Ayir Brown, entering his contract's final year, seeks consistency to earn a new deal. His performance could be pivotal for the secondary. The team also watches the defensive line position, where rookies like James Thompson Jr. and Bryson Eason compete for roster spots.
