Building an elite defense is one thing. Sustaining one year after year is something entirely different. The Philadelphia Eagles understand that championship-caliber defenses aren't rebuilt overnight. They're replenished continuously, often years before obvious needs emerge.
That's why general manager Howie Roseman spent another offseason investing in every layer of Vic Fangio's defense, from established veterans to developmental prospects who may not make their biggest impact for several seasons. Philadelphia's next defensive wave is already beginning to take shape, and it extends far beyond the names expected to headline the starting lineup. It's easy to understand if one looks beyond the obvious.
The Eagles are building depth with a patient approach
Jalen Carter, Nolan Smith, Quinyon Mitchell and
Cooper DeJean have become the faces of one of the NFL's youngest and most talented defenses. First- and second-round picks Jihaad Campbell and Andrew Mukuba represent the next premium investments expected to play major roles in the years ahead.
The Eagles didn't stop there. This past April, Philadelphia continued adding developmental talent on Day 3 of the 2026 NFL Draft, making selections that may not generate immediate headlines but could eventually become important pieces of the franchise's long-term vision.
Safety Cole Wisniewski entered the NFL with an accomplished resume that includes two FCS national championships, first-team FCS All-America honors and recognition as one of the subdivision's top defensive backs. He still has work to do to be better in coverage. He won't be challenging for meaningful defensive snaps until he does.
The Eagles are betting his instincts, physicality and football intelligence can develop under Fangio's coaching staff. Defensive lineman Uar Bernard is already one of the most fascinating projects in Philadelphia's rookie class. Bernard had never played an organized football game before emerging as an NFL prospect, yet his remarkable athletic testing—including a perfect 10.0 Relative Athletic Score after the International Player Pathway Pro Day—made him impossible for scouts to ignore.
At more than 300 pounds with rare explosiveness, Bernard remains a long-term developmental prospect, but his upside is difficult to overlook. Linebacker Keyshawn James-Newby brings another impressive collegiate resume after earning first-team FCS All-American recognition, 2024 First-Team FCS All-American, 2024 First-Team All-Big Sky, and 2025 First-Team All-Mountain West honors during his collegiate career.
Like Wisniewski and Bernard, he'll likely begin his NFL journey competing for a roster spot, contributing on special teams and learning behind established veterans. The Eagles didn't rely solely on the draft to strengthen the defense. Veteran additions Riq Woolen and Jonathan Greenard bring proven production and immediately bolster Philadelphia's defensive depth, while Arnold Ebiketie, A.J. Epenesa and Jonathan Jones provide experienced competition throughout training camp.
None are guaranteed roster spots, but each gives the Eagles additional flexibility while allowing younger players to develop at the proper pace rather than being rushed into significant roles. That approach has become one of Philadelphia's greatest organizational strengths.
Not every Day 3 draft pick will develop into a starter. Some won't make the initial 53-man roster. That's the reality of roster construction across the NFL. The Eagles aren't counting on every prospect becoming a star. They're counting on consistently adding talent, creating competition and developing players long before they're needed.
Carter, Smith, Mitchell and DeJean were once viewed as the future of Philadelphia's defense. Today, they're among its foundation. Campbell and Mukuba appear poised to follow that path, and if the Eagles' recent track record is any indication, a few names currently residing near the bottom of the depth chart may someday become the next wave fans can't imagine the defense without.
