The 2024 NFL season still won't start for another five months. But we can already confidently declare that all eight division winners from last season won't repeat this year.
Four different division crowns changed hands between the 2022 and 2023 seasons, including a worst-to-first situation in the AFC South with Houston Texans. Four occurred the year before that and the year before that, so on and so forth.
The Kansas City Chiefs and Buffalo Bills have won eight and four straight division titles, respectively. Every other division has had at least two different champions over the last four seasons, and all but one (NFC South) had at least three.
