In the history of the National Football League (NFL), there have been many great quarterbacks who have thrown for a lot of yards in a season. However, the record for the most passing yards in a single season is held by Peyton Manning, who threw for 5,477 yards during the 2013 season.

Manning accomplished this feat while playing for the Denver Broncos, and he broke the previous record of 5,476 yards, which was set by Drew Brees in 2011. Manning’s record-setting season was one of the greatest in NFL history, as he threw for 55 touchdowns and led the Broncos to a 13-3 record.
Before Manning and Brees, the record for the most passing yards in a single season was held by Dan Marino, who threw for 5,084 yards during the 1984 season. Marino’s mark stood for more than 20 years before it was broken by Brees in 2011.
Other quarterbacks who have thrown for more than 5,000 yards in a single season include Tom Brady, Matthew Stafford, and Ben Roethlisberger. While these quarterbacks have put up impressive numbers, none of them have been able to surpass Manning’s record.
It’s worth noting that the NFL has become a more pass-heavy league in recent years, which has led to more quarterbacks putting up big yardage numbers. However, even in this context, Manning’s 5,477-yard season stands out as one of the greatest individual accomplishments in the history of the sport.
In conclusion, the record for the most passing yards in a single season is held by Peyote Manning, who threw for 5,477 yards during the 2013 NFL season. Manning’s record-setting campaign was one of the greatest in the history of the sport, and it still stands today as a testament to his talent and skill as a quarterback.
