Purdy’s steady, progression-first approach under Shanahan served as the exact blueprint Darnold absorbed. Watching Purdy’s calm, check-down rhythm and efficient progression helped Darnold believe his own growth was possible, fueling the Minnesota breakout and Seattle’s subsequent pursuit.

Purdy returns fully healthy and is the engine of SF’s high-powered attack. His decision-making, timing, and comfort with Shanahan’s system will be tested by Seattle’s blitz schemes, but a clean opening drive could set the tone for SF’s season.

Purdy carries the weight of a top-market extension and must prove he can drive a high-powered offense around a retooled supporting cast. His performance in 2025 will heavily influence the 49ers' long-term QB plans and fantasy upside, as the team seeks efficiency and stability behind a paid franchise signal-caller.

Purdy is framed as the anchor for SF’s high-powered offense. His connection with Kittle and McCaffrey, plus the offseason signings, creates a gradual ramp for Week 1 expectations as SF navigates a Seahawks defensive test and a potentially conservative early-game plan.

Purdy is listed by SportsLine as a 2025 sleeper QB, slated to outpace Dak Prescott and Bo Nix in ADP terms and possibly approach Mahomes-tier dialogue in a favorable scheme and supporting cast.
