The San Francisco 49ers suffered their second consecutive defeat, losing 22-17 to the Minnesota Vikings and dropping to a 5-2 record this season. Despite having several opportunities to secure the win, the 49ers were unable to capitalize, with quarterback Brock Purdy being intercepted twice, ultimately sealing the victory for the Vikings.

Purdy, who had shown promise in previous games, fell short of leading the team to victory once again. While he played a decent overall game, effectively moving the chains and making timely throws, he stumbled during crucial moments, committing three costly mistakes that cost the 49ers dearly.

The first mistake came at the opening of the second half when Purdy took a 12-yard sack instead of opting for a safer pass, halting the drive. He then threw two interceptions, the first resulting from a poor route by Jauan Jennings, but still an inaccurate pass that ended up in the hands of safety Harrison Smith. The second interception occurred with less than a minute left, as Purdy floated a pass that was picked off by safety Cameron Bynum.

Despite Purdy's shortcomings, he was not alone in being responsible for the loss. The 49ers' pass rush was non-existent throughout the game. Vikings quarterback Kirk Cousins had ample time in the pocket, calmly finding open receivers and remaining unfazed, resulting in the 49ers recording zero sacks and a dismal 15.6% pass-rush win rate, their lowest in years.

The defensive playcalling also came under scrutiny, but the overall lack of pressure on the quarterback remains a major concern for the 49ers, given the investments made in strengthening the defensive line.

Furthermore, the performance of the 49ers' cornerbacks was underwhelming, allowing passes on all levels of the field. A dropped interception by Charvarius Ward proved particularly costly, resulting in a missed opportunity to prevent the Vikings from scoring seven points. The once-strong secondary now faces scrutiny, raising concerns for the team moving forward.

With the trade deadline approaching, the 49ers may consider seeking an upgrade at cornerback, potentially reshuffling their defensive lineup and making a push for the 2023 season. One potential option is Chicago's Jaylon Johnson, although the cost could be a limiting factor for the 49ers.

In conclusion, the San Francisco 49ers' defeat to the Minnesota Vikings has revealed areas of concern for the team. Quarterback Brock Purdy's struggles in critical moments, the lackluster pass rush, and the subpar performance of the cornerbacks highlight the need for improvement in order to remain competitive moving forward.
