The 49ers' goal was to have a quarterback on a rookie contract while using resources to build a dominant roster around the QB. As it turned out, the Niners did benefit from a rookie quarterback contract window. Though Purdy's early contract cap numbers figure to remain manageable, the Niners -- for better or worse -- are now in Purdy's hands. Brock Purdy signed a five-year, $265M contract extension, which ties him to the 49ers until after the 2030 season. Even before Purdy signed his new deal, the effects of the contract were being felt in San Francisco.
