Two NFL teams square off in the preseason with San Francisco focused on validating Brock Purdy and the offense ahead of a potentially high-scoring year. Purdy is positioned to lead a unit that features Christian McCaffrey and a stacked pass-catching crew, including George Kittle and Ricky Pearsall, while Jacob Cowing pushes for real NFL snaps. The defense faces a shorthanded look but is encouraged by early-season adjustments and new depth at corner, depth that could be critical as injuries mount. Raiders discussions center on Aidan O’Connell’s development behind Geno Smith’s misfired veterans and the duo of Jacoby Myers and Davante Adams, with the offense needing to show cohesion quickly. Fantasy takeaways: Purdy’s ceiling rises with health on offense; McCaffrey and Kittle remain keystones; Pearsall and Cowing could become flexible playmakers; Raiders’ QB scenario could swing Week 1 target shares.
