The Indianapolis Colts not only need to be a lot more consistent in 2026 and not have a great start and an awful finish, but to win the AFC South, Indy has to climb over the Houston Texans and Jacksonville Jaguars. Right tackle Braden Smith, going to Houston, won't make that easier.
The Texans had (and likely will still have) a great defense, and after getting off to a wretched start, still won 12 games and made the postseason. What Houston lacked was a good offensive line. According to Pro Football Focus (subscription required), the Texans were ranked 27th among NFL O-lines this past season.
