SF’s bounce-back hinges on Purdy’s health and Shanahan’s adaptability. Purdy’s return stabilizes a top-10 offense behind a revived run game led by McCaffrey, with Aiyuk and Pearsall providing big-play and inside options. Farrell’s blocking addition could unlock more two-TE looks, while the defense—led by Bosa, Warner and Lenior—still carries the unit’s floor, though interior run defense and depth remain questions. Fantasy angles rise with Purdy’s health, CMC’s workload, and which ancillary pass-catchers emerge when the offense is pressed.
