As one decade gives way to the next, the temptation is always to think of this as a line in the historical sand; another era over, a new one just begun.

Mostly this is a quirk of how humans sort everything in their heads; the moments that really do end one era and start another don’t obey calendar rules. The 90s—in the sense of the cultural 90s, the post-Cold War “end of history” 90s—ended on 9/11. Pop culture in the 2010s got a late-00s rolling start; the MCU Infinity Saga began in 2008, while the EDM era of 2010s pop music was preempted by “Boom Boom Pow” tearing up charts in 2009.

But in the NFL, the calendar change and the era change actually match up pretty well; one iconic generation of quarterbacks approaching retirement, the trailblazers for the next just emerging. The NFL they play in will look very different from the one they grew up watching… but not just because of them.

With a new Collective Bargaining Agreement (CBA) potentially imminent, two years left before a new TV deal that could be the biggest shift in NFL broadcasting since FOX stormed onto the scene in 1994, and the still-live possibility of a London relocation that would interact explosively with both of those, the league could loook very different soon, on and off the field. What might change in the 2020s NFL… and what might not?
