Entering this week Houston had a game and a half lead over the Titans and a two and a half game lead over the Colts in the AFC South. Football Outsiders gave the Texans a 72.5% chance at winning the division, the Titans a 14.2% chance, the Colts a 9.5% chance, and the Jaguars a 3.9% chance. You can’t win by losing, but you can lose by not playing. This week both the Titans, who beat the Patriots 34-10, and the Colts, who ended the Jaguars season by beating them 29-26, have made the AFC South something more than an impending conclusion.
