This Day in Eagles History: The Day Philly Almost Lost Fletcher Cox

March 17 isn't just St. Patrick's Day in Philadelphia. Four years ago today, the Eagles pulled off one of the most nerve-wracking salary cap maneuvers in recent franchise history — releasing six-time Pro Bowl defensive tackle Fletcher Cox.

And then signing him right back.

On March 17, 2022, the Eagles released Cox with a post-June 1 designation to avoid $18 million in guaranteed salary that was about to kick in at 4 PM that afternoon. For a few breathless hours, one of the greatest defensive linemen in franchise history was technically a free agent. Any team in football could have called. Any team could have made a pitch.

Nobody in Philly was breathing easy.

Cox wasn't just another guy on the roster. He was THE guy up front for a decade. Drafted 12th overall out of Mississippi State in 2012 — the Eagles traded up to get him — Cox became the anchor of the defensive line through every era of the 2010s. The Chip Kelly chaos. The Doug Pederson magic. The Super Bowl run in 2017, where Cox and that ferocious front four terrorized Tom Brady and the Patriots in Minneapolis. He was first-team All-Pro in 2018, second-team All-Pro three other times, and named to the NFL's 2010s All-Decade Team.

Seventy career sacks. 519 tackles. Sixteen forced fumbles. Three defensive touchdowns. Those aren't just numbers — that's a decade of dominance from a man who played every single season of his career in midnight green.

So when Howie Roseman's front office released him that Thursday afternoon, the panic was real. Eagles Twitter — never known for its calm and measured reactions — went into full meltdown mode. This was Fletcher Cox. This was the heartbeat of the defense.

But Roseman had a plan. He always has a plan.

Within two days, Cox was back. A reworked one-year deal worth $14 million. Same locker. Same number 91. Same guy terrorizing offensive linemen every Sunday. Cox himself later told reporters, "I knew they wanted me back." Classic Fletch — cool as the other side of the pillow while the rest of the city was having a collective heart attack.

The move was pure Howie. Release the guy to reset the cap math, keep the relationship warm, bring him back on terms that work for both sides. It's the kind of financial gymnastics that doesn't make headlines the way a blockbuster trade does, but it's exactly how championship rosters get built and maintained. You don't win Super Bowls by overpaying. You win them by keeping your guys while staying flexible.

Cox went on to play two more seasons in Philadelphia, finally hanging up the cleats after the 2023 campaign. Twelve years, all in midnight green. In an era of constant player movement and free agency chaos, that kind of loyalty is rare. That kind of production is rarer.
