It seems like the 2023 NFL season only just started—that the Detroit Lions and Kansas City Chiefs were kicking off the season at Arrowhead Stadium. But after the conclusion of Sunday night's big showdown between the Buffalo Bills and Miami Dolphins, all 272 regular-season games have been played.
The 2023-24 playoffs are set.

But half of the league's eight divisions weren't decided until Sunday, including one (the AFC East) that came down to the final game of the season.
