San Francisco 49ers quarterback Brock Purdy faces critiques regarding his performance, often attributed to head coach Kyle Shanahan's offensive scheme. Despite this, Purdy demonstrated his ability to extend plays and create opportunities for receivers during training camp, showcasing skills that contribute to the team's offensive success. Meanwhile, the 49ers' secondary is being praised as potentially the best under Shanahan and general manager John Lynch, with players like Deommodore Lenoir making notable plays during practice, including a pick-six. In the first padded practice, Purdy struggled, throwing three interceptions, indicating challenges in the red zone and a strong performance from the defense. Coach Shanahan acknowledged that while the offensive line showed improvement, the defense had the upper hand during the practice. The absence of key offensive starters, like Brandon Aiyuk and Trent Williams, may have impacted Purdy's performance during these drills.
