The AFC South spent years as the conference’s punchline division: no Super Bowl appearances, long droughts, and a reputation for mediocrity. That changed in 2025. Jacksonville went 13-4, won the division at 5-1, and ranked fourth nationally on our efficiency board. Houston went 12-5, also 5-1 in the division, and allowed 17.4 points per game, the best defensive number in the AFC South. Indianapolis started 8-2 and collapsed to 8-9. Tennessee went 3-14 and 0-6 inside the division. ESPN’s AFC South roundtable makes Houston the betting favorite at +110, with Jacksonville trying to repeat as champion for the first time since the division was realigned.
This is part of GameSim’s 2026-27 NFL division preview series. Already posted:
- NFC East: Simulations Back Philadelphia as Clear Division Favorite
- NFC North: Simulations Back Detroit as Clear Division Favorite
- NFC South: Simulations Split Tampa Bay and Atlanta
- NFC West: Simulations Split the Rams and Seahawks
- AFC East: Simulations Favor New England in Both Bills Games
- AFC North: Simulations Split Baltimore and Cincinnati
VSiN’s division preview calls it a three-team race at the top: Houston at +110, Jacksonville at +220, Indianapolis at longer odds after the 8-2 collapse. Our 2026-27 division sims agree that Houston is the team to beat in the head-to-head matchups that matter most. The Texans win 14 of 25 (56 percent) at Jacksonville in Week 6 and 15 of 25 (60 percent) against the Jaguars at home in Week 15. Indianapolis wins 15 of 25 (60 percent) against Houston at home in Week 3. This is not a one-team division on our board, but Houston has the clearest path at the top.
What 2025 actually looked like
Jacksonville went 13-4 and 5-1 in the AFC South. Houston went 12-5 and 5-1. Indianapolis went 8-9 and 2-4. Tennessee went 3-14 and 0-6. The Jaguars ranked fourth nationally at 27.9 points per game and 19.8 allowed. The Texans ranked sixth nationally with the division’s best defense at 17.4 points allowed per game despite scoring less than Jacksonville. Indianapolis ranked tenth with a positive scoring profile dragged down by a 24.2 points-allowed number. Tennessee ranked thirty-first and scored 16.7 points per game.
| Team | Record | AFC South | GameSim rank | Adj. offense (PPG) | Adj. defense (PAPG) |
|---|---|---|---|---|---|
| Jacksonville Jaguars | 13-4 | 5-1 | 4 | 27.9 | 19.8 |
| Houston Texans | 12-5 | 5-1 | 6 | 23.8 | 17.4 |
| Indianapolis Colts | 8-9 | 2-4 | 10 | 27.4 | 24.2 |
| Tennessee Titans | 3-14 | 0-6 | 31 | 16.7 | 28.1 |
Read the table the way the engine does. Jacksonville and Houston both went 5-1 in the division with identical division records. The Jaguars won the tiebreaker with the better overall record and a higher national rank. Houston’s edge was defense: 17.4 allowed versus 19.8 for Jacksonville and 28.1 for Tennessee. Indianapolis scored at nearly the same clip as Jacksonville but ranked tenth because the defense gave too much back. VSiN and ESPN both treat Houston, Jacksonville, and Indianapolis as the relevant teams. The 2025 GameSim baseline agrees. Tennessee is in a different tier on the efficiency sheet.
The 2026-27 setup: Stroud and Lawrence, Jones healthy, Ward in Year 2
Live 2026-27 team rankings are not posted yet, so the 2025 computer is the baseline and the 2027 projected roster file is what the simulator uses until enough real games exist. VSiN and ESPN both orbit the same storylines: C.J. Stroud and an elite Houston defense, Trevor Lawrence running Liam Coen’s offense in Jacksonville, a healthy Daniel Jones with Jonathan Taylor in Indianapolis, and Cam Ward’s second year under Robert Saleh in Tennessee.
Projected pass leaders for 2026-27 in the division:
- Trevor Lawrence (Jacksonville): 3,891 yards, 26 TDs, 13 INTs
- C.J. Stroud (Houston): 3,877 yards, 23 TDs, 11 INTs
- Cam Ward (Tennessee): 3,587 yards, 19 TDs, 10 INTs
- Daniel Jones (Indianapolis): 3,428 yards, 21 TDs, 9 INTs
Projected rush leaders:
- Jonathan Taylor (Indianapolis): 1,509 yards, 12 TDs
- Tony Pollard (Tennessee): 1,044 yards, 5 TDs
- Bhayshul Tuten (Jacksonville): 992 yards, 8 TDs
- David Montgomery (Houston): 936 yards, 7 TDs
Projected receiving headliners: Nico Collins (1,212 yards), Alec Pierce (1,049), Parker Washington (843), Carnell Tate (902). Lawrence and Stroud are essentially tied on passing volume. Taylor’s 1,509 rushing yards lead the division by a wide margin. Collins keeps Houston’s passing tree viable. Ward’s 3,587-yard projection is the Year 2 bet Nashville is making under Brian Daboll.
The title contenders
Houston Texans: the betting favorite the sims trust in the Jaguars matchups
Houston went 12-5, ranked sixth nationally, and allowed 17.4 points per game, the best defensive number in the division. Stroud projects 3,877 yards with Collins at 1,212 receiving yards and Montgomery at 936 rushing yards. ESPN’s reporters and VSiN’s +110 line both install Houston as the division favorite. Our 2026-27 sims agree on the head-to-head slate: 14 of 25 (56 percent) at Jacksonville in Week 6, 15 of 25 (60 percent) against the Jaguars at home in Week 15, 19 of 25 (76 percent) against Indianapolis at home in Week 11, and 20 of 25 (80 percent) against Tennessee at home in Week 18. Houston is not a lock in every division game. It is the team our board picks when the top two meet.
Jacksonville Jaguars: the defending champ who still has to win in Houston
Jacksonville went 13-4, ranked fourth nationally, and projects 3,891 yards and 26 touchdowns from Lawrence with Tuten at 992 rushing yards. VSiN and ESPN both treat the Jaguars as the team trying to repeat for the first time in franchise history in the AFC South era. Our sims add the caveat: Jacksonville is not winning the road games against Houston by default. The Jaguars lose 14 of 25 (56 percent) at Houston’s place in Week 6 and 15 of 25 (60 percent) on the road in Week 15. They beat Tennessee 15 of 25 (60 percent) at home in Week 12 and split coin flips with Indianapolis in Week 8 and Week 18. Lawrence gives Jacksonville a path every week. The division still runs through the Texans on our board.
Indianapolis Colts: the 8-2 team that collapsed, still dangerous at home
Indianapolis went 8-9 after starting 8-2, ranked tenth nationally, and projects 3,428 yards from Jones with Taylor at 1,509 rushing yards. VSiN and ESPN both treat a healthy Jones as the variable that makes the Colts a third-team threat. Our sims give Indianapolis a real home profile: 15 of 25 (60 percent) against Houston in Week 3, 19 of 25 (76 percent) against Tennessee in Week 6, 15 of 25 (60 percent) at Tennessee in Week 15. The road is where the collapse lives. Indianapolis loses 19 of 25 (76 percent) at Houston in Week 11. Taylor and Jones at home can still ruin Houston’s month.
Tennessee Titans: 0-6 in the division, rebuilding on the efficiency sheet
Tennessee went 3-14, 0-6 in the division, and ranked thirty-first nationally with a 28.1 points-allowed number and 16.7 points scored per game. Ward’s 3,587-yard projection and Tate’s 902 receiving yards are the counterargument on the roster file under Saleh and Daboll. VSiN and ESPN both treat Tennessee as a rebuild team with a second-year quarterback. Our sims produce one noisy home number: 22 of 25 (88 percent) against Jacksonville in Week 10. Treat that as a directional read on a small sample, not a prediction that the Titans win the division. They are still the basement team on the 2025 computer.
The games that will decide the division
Featured division games are 25 simulations with 2027 projected rosters and home-field advantage. Treat the percentages as a directional read. Open the prediction page or rerun at 100 simulations for a tighter number.
Sept. 27: Houston at Indianapolis (Week 3)
Twenty-five simulations have Indianapolis 30.2-26.9, winning 15 of 25 (60 percent) at home. The first major upset lean on the board. Stroud on the road against Jones and Taylor at Lucas Oil is not a division coronation for Houston.
Oct. 11: Houston at Tennessee (Week 5)
Twenty-five simulations have Tennessee 28.9-26.7, winning 16 of 25 (64 percent) at home. A moderate home lean for a team that went 3-14 last year. Stroud on the road in Nashville is not automatic even against a rebuild.
Oct. 18: Houston at Jacksonville (Week 6)
Twenty-five simulations have Houston 27.1-25.1, winning 14 of 25 (56 percent) on the road. The first head-to-head lean between the top two. Stroud at EverBank against Lawrence is the game the external previews treat as a division pivot. Our board gives the edge to the betting favorite on the road.
Oct. 18: Tennessee at Indianapolis (Week 6)
Twenty-five simulations have Indianapolis 30.4-23.4, winning 19 of 25 (76 percent) at home. Jones and Taylor at home against Ward is one of the clearest home favorite numbers on the slate for the Colts.
Nov. 1: Indianapolis at Jacksonville (Week 8)
Twenty-five simulations have Jacksonville 26.1-25.5, winning 13 of 25 (52 percent) at home. A coin flip between the third and second teams on the 2025 standings. Lawrence at home against Jones is close enough that the South might still come down to tiebreakers.
Nov. 15: Jacksonville at Tennessee (Week 10)
Twenty-five simulations have Tennessee 31.3-22.8, winning 22 of 25 (88 percent) at home. The loudest surprise on the slate. Open the simulator and rerun at 100 sims if you want to stress-test this one before trusting it.
Nov. 19: Indianapolis at Houston (Week 11, Thursday night)
Twenty-five simulations have Houston 31.1-25.0, winning 19 of 25 (76 percent) at home. Stroud and Collins at NRG against Jones on the road. Our board likes Houston comfortably in a potential seeding game.
Nov. 29: Tennessee at Jacksonville (Week 12)
Twenty-five simulations have Jacksonville 28.2-25.5, winning 15 of 25 (60 percent) at home. Lawrence at home against Ward is one of the spots where our board gives the defending champ a clear favorite number.
Dec. 20: Indianapolis at Tennessee (Week 15)
Twenty-five simulations have Tennessee 28.5-25.3, winning 15 of 25 (60 percent) at home. A moderate home lean in the battle for third place. Jones on the road in Nashville is not automatic.
Dec. 20: Jacksonville at Houston (Week 15)
Twenty-five simulations have Houston 26.3-23.1, winning 15 of 25 (60 percent) at home. The second head-to-head meeting and a potential division decider. Stroud at home against Lawrence is where our board gives Houston the edge again.
Jan. 10: Jacksonville at Indianapolis (Week 18)
Twenty-five simulations have Indianapolis 25.6-26.5, winning 13 of 25 (52 percent) at home. A coin flip to close the regular season. Perfect for a division that might still come down to tiebreakers.
Jan. 10: Tennessee at Houston (Week 18)
Twenty-five simulations have Houston 25.6-20.2, winning 20 of 25 (80 percent) at home. Stroud at NRG against Ward to close the regular season. Our board likes Houston to finish strong at home.

Our working read: Jacksonville is the defending division champion on the 2025 standings and ranked fourth nationally on efficiency. Houston is the betting favorite with the division’s best defense and the team our sims pick in both Jaguars matchups. Indianapolis is the third team that wins 60 percent of a home sample against Houston and 76 percent against Tennessee at home. Tennessee ranked thirty-first nationally and went 0-6 in the division. In a division the previews finally call competitive, the computer agrees on Houston at the top and disagrees on whether anyone else can win the head-to-head games that matter.
