Nick Sirianni was celebrating before Cam Little had even jogged onto the field, a photo of the Eagles’ sideline with arms raised and eight seconds still showing on the clock that spread across football Twitter before Jacksonville had finished lining up for the kickoff that undid it. Philadelphia had just gone up 17-16 on Jake Elliott’s 48-yard field goal in London, and Sirianni’s call afterward — kicking into the landing zone instead of out of bounds — gave Ameer Abdullah a lane for a 53-yard return that left Jacksonville one second and just enough room for Cam Little’s 57-yard walk-off. Final: Jaguars 19, Eagles 17.

Sirianni’s sideline celebrated before the game was actually over, and that photo is now the defining image of a loss built on two separate people acting like someone else was supposed to be managing the ending. Jalen Hurts, asked afterward why the offense didn’t bleed more clock before Elliott’s kick, said managing the clock wasn’t his place to decide.

His fuller answer removed any doubt that it was a slip of the tongue. He’s prepared as a quarterback not to worry about those things, he said. He honors the play call and the things that come into the game. Between a quarterback declining ownership of the clock and a coach choosing the wrong kickoff, nobody on that sideline had decided who owned the final eight seconds.

Damien Harris didn’t bother with the diplomatic version. On CBS Sports HQ’s postgame desk, the former NFL running back called Sirianni’s decision nothing short of coaching malpractice. Harris wasn’t talking about one special-teams call sitting by itself.

He was naming the gap between a staff with eight seconds to defend and a sideline that had already clocked out.

I watched that celebration photo load on my phone four separate times Sunday night, and it looked the same every time: a head coach with his hands up and a game still live in front of him.

This isn’t an isolated case of late-game dysfunction for Philadelphia this year, either. The Eagles lost to Case Keenum earlier this season, a defeat that had nothing to do with talent on the roster and everything to do with execution lapses in exactly the moments a good staff is supposed to tighten up.

London was the same failure with better production values.

Sirianni owned it the moment the game ended. He said he didn’t make the right decision and that he lost them that game, and he put that fully on himself. Credit where it’s due — that isn’t a coach ducking the question. But standing up after the final whistle and claiming the mistake doesn’t retroactively install anyone in the decision chair during the eight seconds that actually decided the game, and nobody was sitting in that chair when it mattered.

Trevor Lawrence called it one of the craziest games he’s ever been a part of, and he’s right, though “craziest” undersells how avoidable it was. Jacksonville still had to survive the long-snapper who nearly cost Jacksonville the same game a chapter earlier, and even that didn’t matter once Philadelphia handed back the only thing it needed to protect.

The Eagles didn’t lose the clock. They lost track of whose job it was.
