Jacksonville Won More Games Than They Deserved. That's the Problem.

The nine-game win streak that closed Jacksonville's 2025 season felt like a coronation. It looked like a team that had figured something out, locked in, found its identity. The box score said 13-4. The vibes said contender. The point differential said: not so fast.

Here is the number that should be stapled to every offseason depth chart in the Jaguars' facility: 7.1. That is the gap, in percentage points, between how often Jacksonville actually won and how often their scoring margin suggested they should have. Their Pythagorean win rate — the projection built from points scored and points allowed across a full season — came out to 69.3%. Their actual winning percentage was 76.5%. That is not a rounding error. That is a team that ran hotter than its underlying performance warranted, and the question entering 2026 is whether the heat was real or borrowed.

To be clear, the offense earned its reputation. Trevor Lawrence threw for 4,214 yards and 32 touchdowns, and Travis Etienne Jr. gave Jacksonville the kind of dual-threat backfield presence that forces defensive coordinators to stay up at night — over 1,500 yards from scrimmage and 14 combined touchdowns across 18 games. Brenton Strange's three-year extension this offseason, worth up to $48 million, signals that the front office is committed to keeping that passing architecture intact. Travis Hunter's return to active status at the start of training camp adds a genuine wild card to a receiving room that already has Brian Thomas Jr. anchoring it. On paper, the offense is better equipped for 2026 than it was going into last September.

The defense is a different conversation. The secondary lost Dane Jackson before he played a single snap in Jacksonville — a retirement that arrived barely a month after he signed, removing a depth piece the team had already factored into its plans. At defensive tackle, the depth situation is genuinely thin: DaVon Hamilton is the only player at that position who logged meaningful time last season, with no established rotation behind him. Two offensive linemen, Cole Van Lanen and Garrett DiGiorgio, remain out of training camp. These are not catastrophic losses in isolation. Together, they represent exactly the kind of structural fragility that a seven-point Pythagorean gap predicts will matter more in 2026 than it did in 2025.

The history of teams that outperform their point differential by this margin is not comforting. Late-game execution and close-game variance are real skills, but they are also the most volatile skills in football — the ones that evaporate fastest when a roster has holes. Jacksonville's October was the tell: a 1-2 month where the margin went sharply negative before the team righted itself. The nine-game run that followed was genuinely impressive, but it was also the kind of streak that can make a front office feel more comfortable than the full-season picture warrants. My read is that the Jaguars are a good football team with a real quarterback and a well-designed offensive system — and also a team that needs to add defensive tackle depth and secondary insurance before September, not after the first losing streak of 2026 forces the issue.
