Brandon Allen secured the backup quarterback position for the 49ers, despite Joshua Dobbs outperforming him in preseason passing yards. Allen has been in San Francisco's system for nearly 18 months and completed 19 of 30 passes for 194 yards during the preseason without any touchdowns or interceptions. Coach Kyle Shanahan's decision to choose Allen indicates confidence in his familiarity with the team’s playbook and systems. As the team prepares for the season opener against the New York Jets, the 49ers are assured of having a capable backup should starter Brock Purdy face any challenges.
