The Offseason Fixed the Wrong Things

Anton Harrison on Injured Reserve is the number that reframes Jacksonville's entire offseason calculus. Not because losing a starting tackle is unusual in the NFL — it isn't — but because the front office spent the better part of four months signaling that offensive line fragility was the one structural problem they understood and were actively solving. Patrick Mekari's back surgery in August forced their hand. They traded for Daniel Faalele. They monitored Cole Van Lanen and Robert Hainsey through camp with the careful attention of people who knew the margin was thin. And now Harrison is gone anyway, and the question the Pythagorean numbers asked all along resurfaces with new urgency: was the 13-4 record a reflection of this roster's actual ceiling, or a favorable compression of variance that the injury ledger is now correcting?

Here is the part that matters structurally. The depth chart at tackle lists Kilian Zierer first and Faalele second. Faalele was acquired specifically as a guard, not a tackle — the Giants trade was a response to interior line concerns, not edge protection. That distinction is not trivial when you are asking Trevor Lawrence to operate behind a reshuffled front. Lawrence threw for 4,214 yards and 32 touchdowns last season, but he did it with a line that was, at minimum, intact. The 14 interceptions in that same line suggest he is not a quarterback who absorbs pressure without consequence. Put stress on the edges and the turnover number is the one that moves first.

The broader roster picture compounds the concern. The Jaguars already carry Patrick Mekari on Injured Reserve from his August back surgery — so the team enters this stretch without two players the front office considered part of their offensive line solution. What remains is a configuration that was never the plan. Faalele at tackle-depth insurance rather than guard specialist. Zierer as the anchor. The pieces are present, but they are playing positions of necessity rather than design, and that distinction tends to show up in the fourth quarter of close games.

What makes this genuinely worrying — rather than merely inconvenient — is the 7.1-percentage-point gap between Jacksonville's actual win rate last season and what their point differential predicted. Teams that outperform their Pythagorean expectation by that margin are typically doing so through execution in close games: turnovers at the right moment, a big play that swings a margin. That kind of performance is real, but it is also fragile. It depends on the quarterback being clean, on the line giving him time, on the offense converting when the game is tight. Harrison's absence puts pressure on exactly the mechanism that generated those wins.

My read is that the front office diagnosed the problem correctly in August — they just ran out of solutions before the season ran out of injuries. Acquiring Faalele was the right instinct. Mekari's surgery was unavoidable. But the Harrison news reveals that the line was never as stabilized as the Week 3 active roster suggested. Jacksonville's weapons — Lawrence, Brian Thomas Jr., Brenton Strange — are good enough to win games with a compromised line. Travis Etienne's 1,174 rushing yards last season show the ground game can carry weight when the passing game is under duress. The question is whether this team can keep winning close games when the structural conditions that produced those wins are quietly eroding beneath them. The numbers from 2025 said this was always a possibility. Harrison's knee is just the confirmation.
