At the midpoint of the season, the Houston Texans are in position to defend their AFC South title.
However, the Indianapolis Colts, who beat the Texans in the playoffs in January and won the first matchup this season, are nipping at their heels.
The Jacksonville Jaguars -- the 2017 division champs who are the only team to interrupt the 10-year reign of either the Texans or Colts for the crown -- are only two games back. As are the Tennessee Titans, who had won two in a row after changing quarterbacks before then losing at the Carolina Panthers on Sunday.
