Current Records: 4,689 (Rich Gannon, 2002)
When the Oakland Raiders signed Rich Gannon as a free agent in February of 1999, few could have expected the kind of run he would have with the team. A journeyman up until that point, Gannon became one of the best quarterbacks in the NFL in Jon Gruden’s offense, twice being named the Pro Bowl Most Valuable Player.
In addition, Gannon would go on to set numerous Raiders records, including the single-season passing yards mark at 4,689 in 2002. During that season, Gannon was named the NFL’s Most Valuable Player, and helped the Raiders to the Super Bowl, where they would eventually be toppled by Gruden and his new team, the Tampa Bay Buccaneers.
Still, Gannon’s single-season mark has never really been challenged, outside of Derek Carr finally eclipsing the 4,000-yard mark in 2018, and a 4,018 yard season from Carson Palmer in 2012. Carr will take a serious shot at the record in 2019, as he has a tremendous amount of weapons in the passing game, and should only improve in his second season running Gruden’s offense.
