Seattle was +8 (7/32) in rest day disparity. That’s basically a 1-bye week advantage. As to travel miles, Seattle (playing in the north west corner of U.S.A.) was 3rd worst.
The NFL could easily keep the swing no greater or worse than +/- 8. Yet, 7 teams were above or below +/- 8 in 2025 and 9 this year.
The NFL could also easily make sure the rest advantage / disadvantage balanced out year-to-year. For example, of the 4 teams > +8 in 2025, they are collectively -11 this year with only one of them in the positive. And 2 of the 3 teams that were < -8 last year are a net +2 this year.
Raiders got royally screwed twice. They are a -32 over 2 years. Saints are 2nd worse over 2 years at -21. LAC is the only other team < -16 at -19—with a whooping -24 this year. Den’s net -1 and KC’s net 0. Only Sea is above +16 over 2 years—which shows the NFL could easily keep it within range, even if it opted to repeatedly benefit or disadvantage a team.
The NFL has just chosen to screw the Raiders. I’m not surprised Saints are next on the list. For whatever reason, the NFL chose to screw LAC this year in favor of Den and KC.
