49ers Secure Brock Purdy with $265M Extension Amid D-Line Overhaul

The San Francisco 49ers enter the 2025 NFL season with a strong offensive lineup, anchored by quarterback Brock Purdy, who recently signed a five-year, $265 million extension, and key players like Christian McCaffrey and George Kittle. Despite early-season absence of wide receiver Brandon Aiyuk due to recovery from ACL and MCL injuries, the team's offense remains among the league's best, largely thanks to head coach Kyle Shanahan's system. However, the defense faces significant challenges, particularly on the defensive line, which has been overhauled with rookies replacing departed veterans, raising concerns about run defense and pass rush effectiveness. Training camp has intensified competition, notably in the safety position, where newcomers like Jason Pinnock and Richie Grant vie for starting roles amid uncertainty. The 49ers aim to address these defensive issues through both offseason acquisitions and draft strategies, with analyst Daniel Jeremiah projecting a cornerback pick to bolster the secondary. Following a disappointing 6-11 season and missing the playoffs, the team and general manager John Lynch have focused on roster improvements to rebound in 2025.
