Kirk Cousins had a standout performance last Thursday, passing for 509 yards and throwing a game-winning touchdown in Atlanta's 36-30 victory over Tampa Bay. However, this impressive feat still did not surpass the long-standing single-game passing record of 554 yards set by Norm Van Brocklin in 1951. Despite modern passing statistics soaring, Van Brocklin's record remains unbroken, with the closest attempt being Matt Schaub's 527 yards in 2012. Van Brocklin's 1951 performance was particularly remarkable as he had never previously thrown for 300 yards in a game. In contrast, many other significant single-game records have been broken or matched in recent years, highlighting the unique endurance of Van Brocklin's achievement.
