Despite a few shaky victories along the way, the Philadelphia Eagles head coach was leading a team that was looking like the NFC’s overwhelming favorite for the Super Bowl at the end of “Monday Night Football” with a road victory against the Kansas City Chiefs and an NFL-best 9-1 record. That evening, at Arrowhead Stadium, Sirianni was captured on tape letting out his emotions without using any weapons as he left the field and into a tunnel. That gave him nine seconds to lose.

“Hi!” Sirianni let out a cry. “Chiefs fans, I don’t hear s*** anymore!”

Sirianni walked a little distance further down the tunnel, looked directly at the camera, and exclaimed once more.

“Seeeee, yaaaaaaaa!” He let out a cry.

It seemed like the first of many high points to come. Rather, it was the forerunner of a valley akin to the Grand Canyon. Yes, the Eagles would go on to defeat the lowly Buffalo Bills in a close overtime match the next week, improving their record to 10-1, but all of that was but a prelude to the unimaginable. Sirianni and his club ended the 2023 regular season with an unexplainable 1–5 slump throughout the course of the following six weeks. In what was billed as a “get right” game for Philadelphia on Sunday, the Eagles, although playing with a shorthanded squad, effectively waved the white flag against a terrible New York Giants club. It was the lowest of lows.

Nothing in the 27-10 defeat was done correctly. Rather, more went awry: From a leg injury to standout wideout A.J. Brown to a hand injury sustained by Eagles quarterback Josh Lanin, there has been a persistent sense that Sirianni’s job security is taking a lot of hits in the closing stages.
