49ers implement new defensive scheme under Raheem Morris at training camp

San Francisco 49ers defensive coordinator Raheem Morris introduced a new defensive scheme during training camp on July 27, 2026, in Santa Clara, California. Morris's approach features a fifth down lineman, differing from the previous four-down front. Quarterback Brock Purdy expressed enthusiasm for the variety this brings to offensive practice. Players have noted it's designed to create confusion for opponents prior to the snap. The 49ers have experienced multiple coordinator changes in recent years but aim to capitalize on the existing talent in their roster. Morris acknowledges the need to build the defense based on the team’s strengths as camp progresses without pads yet.
