Back in 1960 -- not long before the start of the Super Bowl era -- Hall of Fame quarterback Johnny Unitas threw for 3,099 yards, marking the first time in NFL history a player cleared 3,000 yards in a single season.
Roughly 60 years later, we could soon see a quarterback double that mark.
As we enter the 2021 NFL season, 5,477 stands as the NFL single-season passing record, set in 2013 by a 37-year-old fellow named Peyton Williams Manning with the Denver Broncos.
Now that the league has added a 17th game, that record is in immediate jeopardy and a previously unreachable target of 6,000 yards isn't out of the question.
