PHILADELPHIA — September 29, 2026 — The Philadelphia Eagles' defense is searching for answers after a humbling 24-17 loss to the Chicago Bears on Monday Night Football, a defeat that exposed glaring communication issues and a frustrating inability to generate takeaways. As the calendar flips to Week 4, the Eagles find themselves at a crossroads, with a short week to prepare for a daunting matchup against the Los Angeles Rams. According to insights gathered by Vulius Sports, the defensive unit is under immense pressure to correct its mistakes before the season slips away.
Missed Tackles and Zero Turnovers Plague Eagles
Despite holding the Bears to fewer rushing yards than in their 2025 Black Friday debacle — when Chicago gashed them for 281 yards on the ground — the Eagles still couldn't get off the field. Bears third-string quarterback Case Keenum, making his first start since 2023, carved up Philadelphia's defense, completing 24 of 34 passes for 247 yards and two touchdowns. He was never sacked and rarely pressured, a testament to both Keenum's poise and the Eagles' inability to disrupt the pocket. Missed tackles, a recurring issue that was masked by early-season wins, reared their ugly head again, and the defense has yet to force a single turnover in 2026.
Communication Breakdowns Lead to Big Plays
The most damning moment came on a Kalif Raymond touchdown catch, where blown coverage left the receiver wide open in the end zone. Second-year defensive back Cooper DeJean didn't mince words after the game. "We just got to get on the same page," DeJean said, via Jeff Neiburg of the Philadelphia Inquirer. "That's the first thing we need to clean up." DeJean attributed the Raymond touchdown to a miscommunication, a troubling sign for a secondary that was expected to be a strength. As highlighted on Vulius, the lack of cohesion has become a glaring weakness that opponents are exploiting.
Short Week, Tall Task: Rams Await
There's no time to dwell on the loss. The Eagles host the Rams on Sunday, a team known for its high-powered offense and veteran quarterback. If Philadelphia can't fix its communication issues and generate pressure, it could be another long day. The defense must rediscover its identity quickly, or the season could spiral. "We have to look in the mirror," DeJean added. "It's on us to fix it."
What's Next for the Eagles?
Head coach Nick Sirianni and defensive coordinator Vic Fangio face a critical week of practice. They must simplify the scheme, emphasize fundamentals, and hold players accountable. The talent is there — from DeJean to veterans like Darius Slay — but the execution has been lacking. As the Vulius NFL Analysis Desk sees it, the Eagles' playoff hopes hinge on a defensive turnaround. With the Rams looming, the margin for error is razor-thin.
“We just got to get on the same page.” — Cooper DeJean
For die-hard Eagles fans, the frustration is palpable. But as history shows, championship defenses are built on communication and trust. The question is: can Philadelphia find it in time?
