On Sunday, the Indianapolis Colts defeated the Jacksonville Jaguars 16-13 in overtime. It was an ugly game, but in the end the Colts improved to 2-2 on the season and now lead the AFC South after two straight victories over division opponents. Lost in the talk about the game is this fact: with their win on Sunday against the Jaguars, the Colts won their 15th game in a row against the AFC South, tying them for the longest win streak against their division in NFL history. The Miami Dolphins in 1972-73 won 15 games in a row against their division, which until now stood all alone in first place. Now, the Colts have tied the record as they head to Houston for another division matchup this Thursday night against the Texans.
The Colts have completely dominated the division, winning the past two division titles and set up nicely for a third, if they can continue to beat the division opponents. The Colts have outscored division opponents 435-228 during the fifteen-game streak, an average score of 29-15.2 per game (beating opponents by an average of 13.8 points per game). Here's just how dominant the Colts have been during the stretch:
| Date | Opponent | Colts | Opponent |
| 12/30/12 | Texans | 28 | 16 |
| 9/29/13 | Jaguars | 37 | 3 |
| 11/3/13 | Texans | 27 | 24 |
| 11/14/13 | Titans | 30 | 27 |

| 12/29/13 | Jaguars | 30 | 10 |
| 9/21/14 | Jaguars | 44 | 17 |
| 9/28/14 | Titans | 41 | 17 |
| 10/9/14 | Texans | 33 | 28 |
| 11/23/14 | Jaguars | 23 | 3 |
| 12/14/14 | Texans | 17 | 10 |

This Thursday night, the Colts will look to beat the Texans to set the all-time NFL record for wins in a row against division opponents. They have seven more such wins against the next closest active streak in the league, as the Broncos have an eight-game winning streak against their division - but are still a full season's worth of games away from reaching the Colts' mark. It's an incredibly impressive accomplishment regardless of how bad the division has been, as anyone in the league will tell you that division games are always tough. It's an impressive reflection of how dominant the Colts have been in the AFC South recently, and that deserves credit. If they can get a win on Thursday night, they'll be all alone in first place for consecutive wins against division opponents.
