The scenario where every team within a single National Football League division qualifies for the postseason is theoretically possible but statistically improbable under the current playoff structure. The structure allots playoff berths to the four division winners and then awards the remaining three slots in each conference to teams with the best overall records, regardless of division affiliation.
The unlikelihood stems from the inherent competitiveness within a division and across the conference. For such a scenario to occur, teams within a division would need to dominate their inter-divisional games while simultaneously maintaining a superior record compared to the other teams in their conference vying for wild card spots. This requires an unusual confluence of divisional strength and conference weakness. In NFL history, there have been instances of strong divisions sending multiple teams to the playoffs, but never all four.
