San Francisco’s 49ers sit at 2-0 behind a surprising trio of offseason additions. Mac Jones has stepped in smoothly, delivering on-time throws and a focus on the 10–19 yard window, allowing Shanahan’s system to hum even with Purdy sidelined. Bryce Huff’s light-speed edge rush created late-game impact, and rookie Mykel Williams has already shown versatility defending the run on the edge while rushing from inside. Early ROI like this reshapes fantasy value as SF eyes Week 3.
