The same quarterback playing in the same offense with mostly the same players should produce the same results from last year, right? Of course not. The difference is that even if almost nothing changes on a team, they never face the same schedule from year to year. So a part of the valuation of a fantasy player should be if his schedule is easier or more challenging than the previous season.
The fantasy points allowed to quarterbacks by each defense and venue (both at home and away games) were arrayed against each team’s schedule for both 2021 and 2022. Then they are ranked from 1-32 for which teams had the best or worst schedules they played against last year and applied that against what they will face for 2022. Swings of less than 10 in schedule strength ranking say that the schedule isn’t really reliably different for the player.
What is relative is when a player has a significant shift in the quality of defenses that he will face. Davis Mills leaves the No. 32 ranked schedule last year and faces the No. 7 for 2022 – that should be a notable positive for his second year. Conversely, Lamar Jackson went against the No. 8 schedule in 2021 but drops to only No. 26 – that won’t help his passing game that already lost Marquise Brown.
