San Francisco 49ers unveil new defensive schemes under coordinator Raheem Morris

San Francisco 49ers defensive coordinator Raheem Morris introduced a variety of new looks during the team's 2026 training camp, including more frequent five‑man fronts and mixed coverages. The changes depart from the franchise’s long‑standing four‑man front approach that had been employed under previous coordinators.

Players noted the impact of the new concepts: star linebacker Fred Warner said the defense now features “some new things, some new looks,” while quarterback Brock Purdy described the shift as a “different” look that challenges the offense and aids preparation. Offensive lineman Trent Williams also praised the adjustments for providing a good challenge. Morris, who previously used five‑man fronts as head coach of the Atlanta Falcons, aims to add versatile personnel packages, allowing interior linemen such as Mykel Williams to slide into varied roles and giving edge rusher Romello Height more flexibility.

The coaching staff expects the new schemes to evolve throughout the season, with the five‑man front serving as an additional tool rather than a permanent base.
