Aaron Glenn Enters Year 2 With Jets, Ready to Own the Defense He Ran Into the Ground

Aaron Glenn is still the New York Jets’ head coach. After a 3-14 debut season that had “one-and-done” written all over it, owner Woody Johnson kept faith in his first-time coach, and Glenn is now working through his second training camp in Florham Park, New Jersey.

The most damning number from Glenn’s rookie year as a head coach wasn’t the win total. It was zero. As in zero interceptions, the entire 2025 season, the first time that has ever happened to an NFL team in a full 17-game slate. For a coach who built his reputation as a defensive mind in Detroit, that stat line was almost impossible to explain away.

Glenn didn’t try to explain it away. Speaking to reporters at the NFL Scouting Combine in February, he admitted the root problem wasn’t scheme or personnel. It was him stepping back from the controls.

“I didn’t call the defense last year. That was not a good decision by me,” Glenn said, according to ESPN’s Rich Cimini.

That single sentence explains a lot about how the Jets spent their offseason. Glenn had planned to run his operation as a CEO-style head coach in 2025, leaning on coordinators to handle offense and defense while he managed the bigger picture. Defensive coordinator Steve Wilks was fired with three games left in the season and replaced on an interim basis by Brian Duker. By the time the year mercifully ended, it was clear the arrangement hadn’t worked.

So Glenn tore it down and rebuilt it. He fired both coordinators, hired Frank Reich to run the offense and brought back Duker, this time as a defensive coordinator who works alongside Glenn rather than in place of him. Glenn made clear at the Combine that he intends to call the defensive plays himself in 2026, walking back the arm’s-length approach that defined his first year.

“To me, play calling is my superpower, really,” Glenn said, via the Associated Press. “I really missed doing that.”

It wasn’t only the coaching staff that changed. General manager Darren Mougey overhauled the roster around Glenn’s defense, adding players like safety Minkah Fitzpatrick and nose tackle T’Vondre Sweat via trade, and using the No. 2 overall pick in the 2026 NFL Draft on edge rusher David Bailey. As many as eight new starters could open the season on defense, according to Cimini’s reporting. This is Glenn’s unit now, built to his specifications, with no coordinator standing between his instincts and the players on the field.

A former general manager with four decades in NFL personnel experience was blunter about what went wrong in Year 1, telling Cimini that Glenn’s roster looked disengaged.

“They played like a bunch of guys punching time clocks; they didn’t want to be there,” the former GM said, according to ClutchPoints.

That’s a heavy charge for any first-year coach to sit with. Glenn’s response wasn’t to argue the point publicly. It was to change almost everything around him and put himself directly in charge of the unit he knows best.

There’s a personal thread running through all of this, too. Glenn isn’t just coaching the Jets. He’s a former Jets cornerback himself, a first-round pick in 1994 who spent eight seasons at MetLife Stadium’s predecessor before a trade sent him to the Houston Texans. He built his coaching resume later with the Cleveland Browns, the New Orleans Saints and, most notably, four years as the Detroit Lions’ defensive coordinator, where he helped Detroit reach the NFC Championship Game and win back-to-back division titles. That track record is exactly why the Jets hired him in January 2025, and exactly why last season’s defensive collapse felt so out of character.

What Year 2 Looks Like So Far

Training camp opened in late July at the Atlantic Health Jets Training Center, and early reports have shown flashes of the defense Glenn is trying to build. Bailey has drawn praise from teammates for his first-step quickness off the edge, and offensive linemen have already singled him out as a problem to deal with in practice. The defense forced a turnover in an early-August practice period, with linebacker Kiko Mauigoa punching the ball loose on a screen play. There’s real hope inside the building that a defense built almost entirely by Glenn, and now called by Glenn, looks nothing like the one that finished without a single takeaway through the air a year ago.

None of that guarantees anything once the games count. The Jets are still working through camp battles, including an open competition for the backup quarterback job behind Geno Smith, and the offensive line has had its own rough stretches in camp, including communication issues and false-start penalties during a recent practice. But the defensive question, the one that defined Glenn’s first year for all the wrong reasons, is now squarely his to answer.

New York opens its 2026 regular season on September 13 against the Tennessee Titans. For a coach who admitted he made the wrong call by stepping back a year ago, there won’t be anywhere to hide this time. He asked for the job back. Now he has to make it work.
