Who Should I Start? Brock Purdy or Spencer Rattler

Sunday, May 31, 5:26 AM

San Francisco 49ers quarterback Brock Purdy has been an undervalued dynasty asset since coming into the league as the final pick of the 2022 NFL Draft. Since taking over as a full-time starter, Purdy finished as the fantasy QB6 in 2023 and the QB14 in 2024, despite missing two games. While a significant turf toe injury limited him to only nine games in 2025, he was a fantasy difference maker in almost every one of those appearances. From Weeks 11 through 17, Purdy was the QB4, including back-to-back QB1 finishes and a 34.9-point average in the final two games of the fantasy playoffs. Christian McCaffrey, Mike Evans, and George Kittle will all be on the wrong side of 30 for the 2026 season, with Kittle already a question mark for the start of the year as he recovers from a postseason Achilles tear, but when healthy and on the field together, they should create one of the league's most fantasy-friendly groups of pass-catchers in Kyle Shanahan's high-powered offense. Purdy is 26 years old heading into his fifth season, and at RotoBaller's dynasty QB13, he is still undervalued as a perceived QB2 in superflex leagues with legitimate QB1 upside.
