The benchmark for a great season depends on era.
Being a 4,000-yard passer meant something quite different in 1980, 2000 and 2020. The meaning of our standard benchmarks -- like a 1,000-yard rusher or, in fantasy football, a 300-point quarterback -- have shifted over time, but they're also in for a little jolt in 2021 with the addition of a 17th game.
So what did make a great season by position, by era? And how will that extra game impact how we view standard thresholds, NFL records and fantasy benchmarks going forward?
To answer those questions, we started with the historical data since the 1970 AFL-NFL merger and worked our way forward.
