In recent weeks, doubts have begun to surface about the San Francisco 49ers' decision to sign Nick Bosa to a hefty contract extension. As the team evaluates their quarterback options, the focus turns to Jimmy Garoppolo's backup, Sam Darnold, who is poised to step in if necessary.

Bosa's contract extension, which was seen as a significant investment in the team's defense, has raised eyebrows as his performance has waned in recent games against the Cleveland Browns and Minnesota. With his worst statistical outings and three interceptions in the past six quarters, questions are being asked about the wisdom of the extension.

This scrutiny has brought attention to the alternative option at quarterback, Sam Darnold. Darnold, the No. 3 overall pick in the 2018 NFL Draft, possesses the physical skills and accuracy that make him a strong contender for the role. The 49ers coaching staff, including coach Kyle Shanahan, have been impressed with Darnold's ability to make accurate and decisive throws, showcasing his refined passing skills.

It's worth noting that Darnold's NFL experience, though not without its challenges, is valued by the 49ers. With five seasons and 55 starts, Darnold brings a level of experience and understanding of the game. However, skeptics point out his completion percentage of 59.7% and a career passer rating of 78.2, raising concerns about his overall performance.

The competition between Darnold and rookie Trey Lance during training camp ultimately resulted in Shanahan favoring Darnold as Garoppolo's backup. The decision was solidified when Lance was subsequently traded to the Dallas Cowboys for a future draft pick.

Darnold's presence as an insurance policy has been made apparent by the one-year, $5.7 million contract he signed with the 49ers. This deal not only makes Darnold's salary approximately six times higher than Garoppolo's backup, Purdy, but also signifies the team's belief in his capabilities.

Should Darnold be called upon to fill the quarterback role against the Cincinnati Bengals, the 49ers remain confident that their offensive strategy will not need to change. Darnold's familiarity with the team's playbook and his ability to make every throw suggests a seamless transition. However, the question remains whether he can replicate Purdy's timing, anticipation, and precision.

It should be noted that Shanahan's attraction to Darnold dates back to the evaluation process leading up to the 2018 draft, where he thought the young quarterback would be a strong fit for his offensive scheme.

As the 49ers face a crucial decision regarding their quarterback options, the performance of both Garoppolo's backup, Darnold, and Bosa's contract extension will be closely monitored. The outcome of these choices could shape the direction of the team's future on both sides of the ball.
