Cooper DeJeans Sudden Struggles Are Becoming An Eagles Concern

Cooper DeJean faces mounting scrutiny as his tackling struggles raise questions about his performance on the Eagles' defense this season.

Cooper DeJean was a reliable tackler in his first two NFL seasons. This year, that part of his game has slipped, and the Eagles are looking at a noticeable change in a skill that had been one of his strengths.

DeJean was candid after Sunday’s loss to the Panthers when asked about it.

“I don’t know,” DeJean said after the loss to the Panthers on Sunday afternoon. “I just have to find ways to get guys down.

Part of it is different angles and where I’m hitting the guys. But I have no doubt that I’m going to continue to work on that and fix that.

I’ve continued to work on it the last couple of weeks especially and will continue to, to be better in that area.”

There’s no official NFL tally for missed tackles, since the stat is subjective. Even so, the numbers paint an ugly picture.

ProFootballFocus says DeJean has 12 missed tackles this season, most in the league. Among 82 defensive backs with at least 300 snaps, he sits at the top of that list as well, and his 24.5% missed tackle rate ranks third-worst in that group behind only Tre’Von Moehrig (30.8%) and C.J.

Gardner-Johnson (25.7%).

That’s a sharp drop from his previous two seasons:

2024: 11 missed tackles in 19 games (13.8%)

2025: 11 missed tackles in 17 games (10.9%)

2026: 12 missed tackles in 6 games (24.5%)

Stathead’s chart tells a similar story. It has DeJean with seven missed tackles this season, which is tied for second-most, compared with just 14 across his first two full NFL seasons combined.

Eagles defensive coordinator Vic Fangio pointed to one possible reason for the downturn.

“There's just been a few more than usual,” Fangio said. “He did get that stinger when he had to come out of the Rams game, I believe it was. I think that's affected him a little bit.”

DeJean, 23, was hurt in that Rams game and missed a few snaps. The next week in London, he had his roughest tackling performance of the season, missing five tackles in one game according to PFF. That makes Fangio’s explanation worth considering.

Fangio also pushed back on the idea that DeJean’s missed tackles are tied to more work at safety. He said the Eagles haven’t really been in their base defense much, so the position switch alone doesn’t explain the problem.

DeJean said he isn’t leaning on that as a reason, either.

“I still got to be able to tackle better and get guys to the ground,” he said.

Nick Sirianni Just Reignited A Debate Eagles Fans Know Well

Nick Siriannis sideline fire has always been part of the package in Philadelphia, where intensity is often treated as a feature until it starts crossing a line. During the NFLs fall meetings in New York City, the Eagles coach was one of three head coaches fined for conduct toward game officials, a reminder that the league is watching closely when emotions spill over into interactions with referees.

The bigger question around Sirianni is not whether he cares, because everyone around the Eagles knows he does, but how that edge is managed over the long haul. Jeffery Lurie has already spoken publicly about the fine line there, acknowledging that Siriannis passion can become counterproductive if it goes too far with officials, which is exactly why this latest episode has reopened a familiar debate in Philly.

Cowboys Bring Extra Rivalry Juice Into Massive Eagles Showdown

The Week 7 meeting between the Cowboys and Eagles already had the feel of one of the most charged games on the NFL calendar, and it only gets a little extra shine with Monday Night Football set for Oct. 26 at Lincoln Financial Field. Kickoff is scheduled for 8:15 p.m. ET, with ESPN, ABC and Disney+ carrying the game as Philadelphia and Dallas take another swing at each other in front of a national audience.

Dallas also is bringing its Arctic White Color Rush look back into the spotlight, a uniform combination that has been part of a perfect run so far this season. For the Eagles, the matchup is a straightforward one on the field but a familiar one in every other sense, with the rivalry, the stage and the timing all adding to the sense that this one could feel bigger than an ordinary division game.

Eagles Head Into Cowboys Showdown With Their Season Already Feeling Fragile

The Eagles Week 7 trip to Dallas arrives with both teams stuck at 2-4, turning Monday Night Football into a meeting of two frustrated rivals instead of the kind of showcase either side expected in October. Philadelphia is already fighting through a run of injuries, and the schedule leaves little time to reset before an 8:15 p.m. EST kickoff on ABC and ESPN.

Much of the attention now centers on how the offense will piece itself together heading into a game that could shape the tone of the next month. One potential boost is at least on the horizon, with Saquon Barkley in line to work his way back after missing the last two games, but the larger questions around the Eagles remain the ones that have made this season feel so shaky.
