Brandon Allen is noted for his lackluster performance as a fill-in quarterback, having thrown for only 48 yards on 21 attempts in a game during the 2020 season. His inclusion in the list of players with over 20 pass attempts and under 50 passing yards highlights the rarity and severity of such a performance, placing him alongside a struggling Peyton Manning and Cooper Rush's recent outing.

Brandon Allen is next in line to take over as the starting quarterback for the 49ers if Brock Purdy is unable to play due to his back soreness. His readiness to step up will be crucial as the team faces a challenging matchup against the Patriots while already missing key offensive players like Deebo Samuel, George Kittle, and Christian McCaffrey.

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.

Brandon Allen is listed as one of the backup quarterbacks on the 49ers' roster, contributing to the team’s overall budget strategy, as the quarterback position is the cheapest on the team this season. His presence underscores the financial flexibility the 49ers have been able to enjoy, allowing them to invest heavily in other positions. In a critical year where the team seeks to leverage Purdy's low salary before he requires a more substantial contract, Allen's role is tied to the team's broader cap management and future decisions regarding their quarterback situation.

Brandon Allen is in contention for the backup quarterback position behind Brock Purdy. In the preseason, he completed 19 of 30 passes for 194 yards, without throwing any touchdowns or interceptions. Allen, now in his second season with the 49ers, has nine regular-season starts under his belt, providing him with valuable experience as the team evaluates its options. Coach Shanahan indicated that decisions may change based on the team's game plan and the opponent's needs.
