The AFC South division was created in 2002 during a league-wide realignment that expanded the NFL to thirty-two teams. This new structure formed from two former AFC Central teams, one AFC East team, and an expansion team.
The four franchises in the AFC South are the Houston Texans, Indianapolis Colts, Jacksonville Jaguars, and Tennessee Titans. The Texans joined as an expansion team while the other three moved or were reorganized into this grouping before the 2002 season.
The Tennessee Titans won the inaugural 2002 AFC South division title and advanced to the AFC Championship game. They defeated their divisional rivals to secure the top spot for that year.
The AFC South holds the longest active Super Bowl victory drought among all eight divisions since its formation. No team within this specific grouping has won a Super Bowl since the Indianapolis Colts victory in 2006.
The Houston Texans have won the AFC South division title multiple times including victories in 2011, 2012, 2015, and 2016. Their 2011 win marked the franchise's first playoff qualification after ten seasons of existence.
