Mac Jones Joins 49ers as Backup Under Coach Shanahan

Mac Jones, once a highly regarded quarterback prospect, was originally passed over by the San Francisco 49ers in the 2021 NFL Draft when Kyle Shanahan chose Trey Lance instead. Jones was drafted by the New England Patriots, where he had a promising rookie season but subsequently experienced a career decline, leading to stints with the Jacksonville Jaguars and now returning to the 49ers in 2025 on a two-year deal. Serving as the backup to Brock Purdy, who signed a lucrative five-year contract, Jones embraces the opportunity to learn Shanahan’s quarterback-friendly offense, praising its emphasis on timing, rhythm, and clear explanations of plays. Despite being a backup, Jones is optimistic about improving his consistency and values the chance to be part of a system that has successfully elevated quarterbacks like Purdy and Jimmy Garoppolo. The reunion with Shanahan is seen by Jones as a potential reclamation project to revive his career, even joking about any past draft snub tensions. Ultimately, Jones appreciates the fit with the 49ers' offense and expresses excitement to grow under Shanahan’s guidance while acknowledging the unpredictable nature of his NFL journey.
