The Houston Texans lead AFC South champion markets at 46.5% implied probability, driven by their elite defense that ranked among the league’s best in recent seasons and quarterback C.J. Stroud’s development, bolstered by offseason additions like running back David Montgomery. The Jacksonville Jaguars sit at 27.5% as defending division winners with a balanced attack led by Trevor Lawrence, though roster changes have tempered expectations. Indianapolis Colts hold 21.5% on the strength of a capable offense and defensive reinforcements like cornerback Sauce Gardner, positioning them as a competitive third option. The Tennessee Titans trail at 5.5% amid a rebuilding phase under new coaching. Early 2026 outlooks reflect these rosters and recent performance trends entering the regular season.
