SF closed the preseason with a 30-23 win over the Chargers, but the real takeaway is the 53-man roster clock ticking down. Defensive depth dominated the night, with Jordan Elliott, Renardo Green, Marquese Sigle and Ji'Ayir Brown logging heavy snaps as SF shapes its safety rotation behind Jason Pinnock. Connor Colby flashed versatility on the line, hinting at Week 1 guard possibilities as Ben Bartch’s health remains a variable. Jeff Wilson Jr. surged for 41 yards and a TD, complicating Guerendo and James’ roster cases. Skyy Moore’s debut was uneven, underscoring a gradual ramp for his offensive impact. DTs Bruce Hector, Sebastian Valdez and Evan Anderson showed punch from depth, offering optimism for the regular season.
