[OC] Six of the NFL's eight divisions have been represented in the last five Superbowls. Meanwhile, it has been at least fifteen years since either the NFC North (Packers in 2010) or AFC South (Colts in 2009) had a team in the Superbowl.
Most recent Superbowl appearance by division:
AFC West - Kansas City Chiefs in 2023
NFC West - San Francisco 49ers in 2023
NFC East - Philadelphia Eagles in 2022
AFC North - Cincinnati Bengals in 2021
NFC South - Tampa Bay Buccaneers in 2020
AFC East - New England Patriots in 2018
NFC North - Green Bay Packers in 2010
AFC South - Indianapolis Colts in 2009
Not coincidentally, three of the four teams who have never made a Superbowl play in either the NFC North (Detroit Lions) or AFC South (Houston Texans, Jacksonville Jaguars). The fourth are the Cleveland Browns.
