San Francisco 49ers quarterback Brock Purdy has struggled during training camp, throwing seven interceptions over two practices, including four in just five attempts on Tuesday. Purdy's performance has drawn comparisons to a previous difficult outing by Jimmy Garoppolo in 2019, though teammates maintain that his overall improvement and confidence remain evident. Despite the interceptions, Purdy started practice well, completing his first eight passes, including a notable 50-yard throw to Deebo Samuel. Defensive players, particularly cornerback Deommodore Lenoir, have capitalized on Purdy's errant throws, showcasing strong performances throughout the camp. Some key starters, like Trent Williams and Brandon Aiyuk, have yet to participate, potentially impacting Purdy's offensive chemistry. The team remains optimistic about Purdy's trajectory as he navigates this pivotal season ahead of a potential contract extension.
