The AFC South has four teams with four very different stories to tell in 2025.
Houston’s arc is straightforward: keep a rising core together through a bit of roster surgery and make it three straight division titles. Indianapolis just made the splashiest quarterback decision of the summer—signing Daniel Jones and handing him the job—while carefully preserving Anthony Richardson’s long-term runway. Jacksonville hit the reset button with a new head coach and a two-way rookie who changes the geometry of every snap. Tennessee, now led by No. 1 pick Cam Ward, re-laid its offensive line and is betting that a functional run game plus a ball-control passing plan can keep scores in the teens and low 20s.
The numbers give us a tight top three and a live long shot. AccuScore’s preseason win expectations put Houston at 9 (playoffs 59.73%, division 51.12%) against a Vegas total of 9.5 (playoff implied 59.18% at -145, division 50.0% at +100). Indianapolis lands at 8 wins (playoffs 33.74%, division 24.19%) versus 7.5 in the market (playoff implied 33.33% at +200, division 22.22% at +350). Jacksonville sits at 7 wins (playoffs 25.66%, division 18.0%) against 7.5 (playoff implied 37.04% at +170, division 25.0% at +300). Tennessee projects to 6 (playoffs 10.74%, division 6.69%) versus 5.5 (playoff implied 19.05% at +425, division 11.76% at +750). On paper, it’s the Texans’ race to lose; in practice, the Colts’ QB pivot, the Jaguars’ coaching change, and the Titans’ trench overhaul mean the favorite will be working without a net.
Below, we use the same structure you liked—the big swing, the coach’s hand, key transactions, the roster spine, and the numbers—to show how the South will actually be decided on Sundays.
Houston Texans: Threading the Needle While Keeping the Core Scary
The big swing
Houston chose balance: accept short-term turbulence up front to fix the cap and depth chart while keeping the Stroud-centric core intact. Trading Laremy Tunsil cleared a long-term path; signing stopgaps and drafting immediate contributors is how you keep the window from wobbling while the line resets. Meanwhile, the backfield safety net is real: with Joe Mixon on the reserve/NFI list to start the year, the Texans added Nick Chubb on a one-year deal to stabilize early-down efficiency and protect the play-action game until Mixon returns.
The coach’s hand
DeMeco Ryans builds from a fast front and a DB room that plays on a string. Offensively, the calling card remains space and timing—spread you horizontally, punish leverage, then hit in-breakers when safeties widen. Houston’s staff is comfortable winning “boring” snaps on both sides: four-yard runs, second-and-six, rally-and-tackle on the perimeter.
Key transactions that actually matter
Trades
- Moved Laremy Tunsil to Washington, accelerating the offensive line’s refresh.
- Dealt John Metchie III to Philadelphia for Harrison Bryant, adding a reliable move TE to the sub-package menu.
Free agency
- Cam Robinson (LT) and Laken Tomlinson (G) arrived on short-term deals to keep protections coherent while young linemen grow.
- Nick Chubb signed a one-year contract to anchor the backfield while Mixon heals.
Draft
- Jayden Higgins (WR) offers size and ball-skills to complement Nico Collins and Tank Dell.
- Aireontae Ersery (OT) and Jaylin Noel (WR) deepen the two spots Houston attacked in March.
The roster spine
- QB/skill: C.J. Stroud manipulates windows like a veteran; with Collins/Dell/Higgins and Harrison Bryant as a chain-mover, Houston can stay ahead of the sticks without demanding five-step heroics every drive.
- Front seven: Will Anderson Jr. and Danielle Hunter give Houston a rare two-pronged edge presence. That allows Ryans to disguise late without sending help.
- Secondary: Derek Stingley Jr. and Jalen Pitre headline a unit that drives the scheme—tight zones, rally, and finish. When Houston plays with a lead, their pursuit speed pops.
The numbers (and what they imply)
The model sits at 9.0 wins, 59.73% to make the playoffs, 51.12% to win the division; the market is essentially in lockstep (9.5 wins; playoffs 59.18% at -145; division 50% at +100). That’s “favorite but fragile,” the profile of a team that will play a month with a patchwork run game and a reconfigured line—and still expects its defense and quarterback to solve the margins.
Bottom line: If the line gels and Chubb gives them steady early-down outcomes until Mixon returns, Houston’s structure—plus the Anderson/Hunter closer package—keeps them on the inside track.
Indianapolis Colts: Daniel Jones Now, Anthony Richardson’s Future Later
The big swing
Indianapolis didn’t hedge: it signed Daniel Jones and named him the Week 1 starter, then doubled down on protecting him and getting off the field on third down. The subtext is as important as the headline: the Colts did not move Anthony Richardson. He remains in the building with a long runway, but 2025 is Jones’s audition.
The coach’s hand
Shane Steichen is a QB-friendly problem-solver: RPOs to clear pictures, play-action to open crossers, and packaged plays that let the quarterback be right against multiple coverages. Defensive coordinator Gus Bradley remains committed to zone structure and leverage—tackle, deny explosives, earn third-and-long.
Key transactions that actually matter
Quarterback
- Signed Daniel Jones (one year) and declared him the starter—full stop. The staff’s message: we’re going to play clean football while Anthony Richardson develops and gets fully healthy. The organization has stated it isn’t shopping Richardson; 2026 decisions will flow from what happens this season.
Secondary
- Signed Xavien Howard to add a proven outside corner.
- Traded for Mekhi Blackmon, deepening a CB room that needed multiple playable answers.
Draft
- Tyler Warren (TE) headlined a class built for immediate snaps; he’s a red-zone and third-down helper.
- J.T. Tuimoloau (EDGE) and Justin Walley (CB) fit the identity: affect the passer, finish the tackle.
- Day-3 adds like Jalen Travis (OT) and DJ Giddens (RB) round out the depth chart.
The roster spine
- QB/skill: Jones gets a quality trio in Michael Pittman Jr., Josh Downs, and Adonai Mitchell, with Jonathan Taylor setting the down-and-distance table and Tyler Warren giving Jones the “boring six yards” when the coverage wins.
- OL: A healthy Quenton Nelson next to Braden Smith and a deep swing-tackle picture should keep the menu open.
- Defense: DeForest Buckner remains the tentpole up front; if the Howard/Blackmon moves lift the coverage floor, the pressure and takeaways follow.
The numbers (and what they imply)
AccuScore has Indy at 8.0 wins, 33.74% to make the playoffs, 24.19% to win the South. The market is a hair lower on the division but broadly aligned (7.5 wins; playoffs 33.33% at +200; division 22.22% at +350). That’s exactly what a QB change plus defensive reinforcements should look like: viable path, volatile week-to-week.
Bottom line: If Jones plays on time and the CB room is as upgraded as the paper says, the Colts are the Texans’ biggest problem. Richardson’s future? Still very much alive—this season informs how they structure that future, it doesn’t foreclose it.
Jacksonville Jaguars: Liam Coen’s Clean Slate—and a Two-Way Unicorn
The big swing
Jacksonville made two decisions that reframe the franchise: hired Liam Coen as head coach and drafted Travis Hunter, the two-way phenom who legitimately impacts both sides of the ball. Add an in-season wideout trade and a center-for-defender swap, and this is a different team than the one that stumbled last fall.
The coach’s hand
Coen’s offense is about presentation and answers: motion to reveal coverage, condensed splits to create space for crossers, and a heavy does of play-action shots that look like runs until they’re not. Defensively, simplicity and speed—don’t bust, rally, and let the front hunt.
Key transactions that actually matter
Trades
- Acquired Tim Patrick to add a big-frame veteran to a youthful WR room.
- Swapped Luke Fortner (C) to the Saints for Khalen Saunders (IDL), trading interior pass pro for early-down beef.
Free agency
- Signed Dyami Brown, giving Trevor Lawrence another run-after-catch threat and a vertical answer opposite the big body.
Draft
- Travis Hunter (WR/CB) is the headline. If he plays 50–60 snaps on offense and a sub-package role on defense, his impact on spacing and opponent game plans is immediate.
The roster spine
- QB/skill: Trevor Lawrence gets a diversified room: Brian Thomas Jr. (the rising star), Hunter (two-way stress), Patrick (possession and blocking), Dyami Brown (verticals), Travis Etienne Jr. (option game and screens). That’s a lot of ways to be right.
- OL/front: Fortifying the interior with Khalen Saunders and leaning on Walker Little/Ezra Cleveland to stabilize protection is the swing factor.
- Defense: If Tyson Campbell returns to form and Hunter can play situational snaps at corner, Jacksonville’s back end can survive while the front finds a rotation that wins on standard downs.
The numbers (and what they imply)
AccuScore says 7.0 wins, 25.66% playoffs, 18.0% division. The market is notably more optimistic (7.5 wins; playoffs 37.04% at +170; division 25.0% at +300). That spread is a referendum on Coen + Lawrence + Hunter. If the protection holds and the red-zone rate pops, the optimistic case looks less like faith and more like math.
Bottom line: Coen’s structure plus Hunter’s gravity can flip two or three coin-flip games. That’s the difference between sneaking over .500 and staring at 7–10 again.
Tennessee Titans: A New Quarterback and an Old-School Blueprint
The big swing
The Titans took Cam Ward No. 1 overall and then built a cocoon: significant offensive-line investments, a veteran receiving corps anchored by Calvin Ridley, and a defense that tries to keep games on script while Ward learns the NFL’s language.
The coach’s hand
Ball control on offense, simplicity on defense, and a mandate to win first down. That’s been the staff’s throughline. Expect heavy use of quick game, defined-read play-action, and a run plan that aims for four yards at a time. On defense, more two-high shells, keep a lid, and ask your edges to earn a handful of true wins each week.
Key transactions that actually matter
Free agency
- Fortified the offensive line with Dan Moore Jr. (four years) and Kevin Zeitler (one year). Added Xavier Woods at safety and Dre’Mont Jones to the front.
- Signed Van Jefferson to diversify the WR room around Ridley.
The room around Ward
- Tony Pollard returns as the lead back, with Tyjae Spears in a change-of-pace role when healthy. The idea is simple: stay on schedule so Ward’s shot plays are selections, not necessities.
The roster spine
- QB/skill: Ward’s arm talent and mobility show up on layered throws. Ridley is the route-winner who gives him precise answers on third down; Jefferson stretches zones horizontally.
- OL: The Moore/ Zeitler adds aim to turn 2nd-and-9 into 2nd-and-6. If that happens, the rookie looks ready faster.
- Defense: L’Jarius Sneed headlines a secondary built to smother explosives; Dre’Mont Jones and the front aim to squeeze pockets rather than chase sack totals.
The numbers (and what they imply)
AccuScore is tepid—6.0 wins, 10.74% playoffs, 6.69% division—while the market prices in rookie-QB variance and the trench rebuild (5.5 wins; playoffs 19.05% at +425; division 11.76% at +750). That’s a fancy way to say: if Ward hits early, everything moves.
Bottom line: With cleaner protection and a WR1 who separates, Tennessee has a path to feisty. If the defense avoids the explosive bleed, they’ll live in one-score games—and those are coin flips.
The Cross-Currents That Will Decide the South
- Protection, not perfection. Houston’s remodeled line, Indy’s interior cohesion, Jacksonville’s center shuffle, Tennessee’s new left tackle/right guard tandem—whoever keeps their QB clean on second down will own September.
- Early-down boredom. Chubb’s four-yarders while Mixon heals; Taylor’s steady churn; Etienne on counters and screens; Pollard on duo—that’s the backbone. If these teams live in 2nd-and-6, the play-callers get to call their game instead of chasing.
- Explosive management. Coen’s motion-heavy shot game in Jacksonville, Stroud’s middle-window daggers, Indy’s Pittman/Mitchell dig-glance package, Tennessee’s carefully rationed deep balls—explosives will decide the two head-to-heads that swing the division.
- Third-level communication. Houston’s back end plays fast when the rules are clean. Indy added veteran corners for a reason. Jacksonville will be mixing youth with newcomers. Tennessee wants to live two-high and keep the lid on. Week-to-week, the team that avoids the busted touchdown wins the quiet edges.
What the Betting and Model Gaps Really Mean
- Texans: 9.0 wins vs 9.5; 59.73% model playoffs vs 59.18% implied; 51.12% model division vs 50% implied. Consensus favorite, with minor uncertainty priced into the line/backfield.
- Colts: 8.0 wins vs 7.5; 33.74% vs 33.33% playoffs; 24.19% vs 22.22% division. Jones’s floor + a sturdier CB room is exactly a “live in Week 17” profile.
- Jaguars: 7.0 wins vs 7.5; 25.66% vs 37.04% playoffs; 18.0% vs 25.0% division. Markets are buying Coen + Hunter + Lawrence variance; models are waiting on proof in the trenches.
- Titans: 6.0 wins vs 5.5; 10.74% vs 19.05% playoffs; 6.69% vs 11.76% division. A classic rookie-QB dispersion curve: if Ward is ahead of schedule, the over and the long-shot division ticket both get interesting.
Week-to-Week Ingredients to Track
- Houston: Early-down run success while Mixon sits; Robinson/Tomlinson pressure rates allowed; Hunter/Anderson snap-to-impact ratio on money downs.
- Indianapolis: Jones’s time-to-throw and play-action usage; Howard/Blackmon completion percentage allowed vs. WR1s; Tyler Warren red-zone targets.
- Jacksonville: Travis Hunter’s snap distribution (WR vs. CB) and target depth; interior OL pressure rates after the Saunders/Fortner swap; Etienne’s usage in the pass game.
- Tennessee: Ward’s air yards per attempt by down; Moore/ Zeitler penalties vs. pressures (rookie QBs hate drive-killers); explosive-pass rate allowed with Sneed on the field.
The People Who Will Decide It
Houston Texans
C.J. Stroud is the division’s best rhythm thrower—and its best manipulator of underneath windows. Nico Collins is the boundary answer; Tank Dell changes angles after the catch; Jayden Higgins should become the “win on the body” outlet. Nick Chubb gives the run game gravity while Joe Mixon heals. On defense, Danielle Hunter and Will Anderson Jr. are a relentless closing duo, and Derek Stingley Jr. turns late throws into breakups. Ryans’s weekly edge is structure: Houston rarely beats itself.
Indianapolis Colts
Daniel Jones gets the first shot to run Steichen’s menu—RPOs, play-action, and leverage throws to Michael Pittman Jr., Josh Downs, and Adonai Mitchell. Jonathan Taylor is still the stressor; if the line gets him through to the second level, the Colts’ whole profile changes. Tyler Warren gives third-down and red-zone clarity. Defensively, DeForest Buckner is the problem every protection meeting starts with; the new corner tandem (Xavien Howard, Mekhi Blackmon) must convert “we were in phase” into passes defended.
Jacksonville Jaguars
Trevor Lawrence now has a room that makes sense: Brian Thomas Jr. as the emergent WR1, Travis Hunter as a formation-proof decoy/weapon, Tim Patrick for the in-breaking, contested stuff, Dyami Brown to keep safeties honest, Travis Etienne Jr. as the outlet. Coen will sequence to create two or three premium shots a game—if the protection holds, those become points. On defense, Tyson Campbell and a deeper front help them play fast; Hunter’s situational CB snaps could be the quiet difference in two wins.
Tennessee Titans
Cam Ward’s processing and off-script control are the Year-1 barometers. Calvin Ridley remains a technician who makes the QB right; Van Jefferson and the backs keep the schedule honest. Up front, Dan Moore Jr. and Kevin Zeitler are the keystones to everything they want to be. L’Jarius Sneed lets the defense protect the sky while Dre’Mont Jones and the front try to squeeze the pocket. If the Titans stay out of third-and-longs, they’ll drag people into four-minute games.
A Division in One Paragraph
Houston has the best blend of quarterback, front-seven disruption, and system continuity; that’s why it’s the favorite. Indianapolis is the best bet to make this uncomfortable, because Jones’s floor plus a healthier, deeper defense travels—and Richardson still gives them optionality beyond 2025. Jacksonville’s upside rides on Coen’s structure and Hunter’s gravity; if both hit, their seven-win projection becomes stale in a hurry. Tennessee will look like a different team by Thanksgiving if the line holds and Ward’s decisions speed up. The standings should shade in that order—but the margin is thinner than the chalk suggests.
Final Thought
The AFC South tends to be decided by the unglamorous stuff—second-and-medium conversions, tackling in space, a single protection check in the middle eight. Houston owns that space until someone jostles them off it. Indianapolis has the personnel and plan to try. Jacksonville just changed the conversation. Tennessee is building a sustainable way to play around a rookie. The fun is in how fast each of those bets pays off.
