Cooper DeJean at safety is one of the more interesting Eagles experiments to watch

Cooper DeJean is going to get a new look in the Eagles defense this year, and honestly, it should be pretty fascinating to see how Vic Fangio uses him.

According to Jeff McLane, Fangio told reporters that Cooper DeJean will play safety in base packages, then move back into the slot when the Eagles go nickel.

Cooper DeJean is moving to SAFETY in the Eagles base defense, per Vic Fangio.

Last year as a slot CB, he ranked #1 in:

🔒 PFF coverage grade
🔒 Catch rate allowed
🔒 Passer rating allowed
🔒 Yards per coverage snap

Now he plays everywhere. 🦅 pic.twitter.com/ygTOrxwnuN

That is a pretty big change from last year, when Cooper DeJean started at outside corner in base looks before sliding inside. Now, the Eagles are putting even more on his plate.

And that makes sense.

DeJean is not just a slot corner. He is one of the smartest and most versatile players on the defense. He can cover. He can tackle. He can play in space. He can process what is happening in front of him. Those are all traits that translate pretty naturally to safety, at least in theory.

Now we get to see what it actually looks like.

Cooper DeJean Gives Fangio More Flexibility

The most interesting part of this move is not just the position label. It is what it lets Fangio do.

If Cooper DeJean can hold up at safety in base packages, the Eagles can stay more multiple without taking one of their best defensive backs off the field. Then when they go nickel, he can slide right back into the slot, where he has already been ridiculous.

That is a nice luxury to have.

DeJean was already one of the best slot corners in football. He ranked at or near the top of the league in coverage metrics and looked comfortable almost immediately. That does not happen by accident.

So this is not the Eagles trying to fix a problem. It feels more like Fangio looking at a really good player and seeing how much more he can handle.

There is always some risk with that. Moving a guy around can get tricky. You do not want to overcomplicate things for a young player who is already elite at one job.

But DeJean does not really seem like the kind of player who gets overwhelmed by more responsibility. If anything, this is probably the kind of role he was built for.

This Could Make The Eagles Defense Harder To Read

The Eagles already have Quinyon Mitchell locking down one side, and now they gave Tariq Woolen on the other. They already have a secondary full of young talent. Now they can use DeJean as more of a movable piece depending on the package.

That is where this gets fun.

In base, he can play safety.

In nickel, he can play slot.

Depending on the look, he can help disguise coverage, match up with tight ends, handle slot receivers, trigger downhill in the run game, or give Fangio more options post-snap.

The Eagles do not need him to become Brian Dawkins overnight. Nobody is asking him to do that. But if he can be steady at safety in base and still dominate in the slot, that is a serious weapon.

And with Fangio, it is never just about where a player lines up. It is about what the offense thinks it is seeing before the snap, then what the defense actually becomes after the ball is snapped.

DeJean gives him more ways to play that game.

Cooper DeJean Has Already Earned The Trust

This is the kind of move that says a lot about what the Eagles think of Cooper DeJean.

Young defensive backs usually do not get moved around this much unless the coaching staff trusts them. Fangio clearly does. That alone is worth paying attention to.

DeJean was already a major part of the defense. He was already a Super Bowl hero after taking Patrick Mahomes the other way for a pick-six. He was already one of the best young defensive backs in the NFL.

Now the Eagles are asking him to become even more useful.

That is what makes this worth watching. Not because it is guaranteed to be perfect right away. Not because safety is suddenly his long-term home. But because the Eagles have a player talented enough to even try this with.

A lot of teams talk about versatility. The Eagles actually have it.

Let’s See What It Looks Like

The move sounds good on paper. Cooper DeJean has the skill set for it. Fangio has the brain for it. The Eagles have enough talent in the secondary to experiment with it.

Now it just has to work on the field.

That is the part I’m interested in seeing.

How often does DeJean actually line up deep? How much does he rotate down? Does he look natural handling run fits from safety? Does Fangio use him to disguise coverage more? Does this make the Eagles harder to attack on early downs?

Those are real questions.

But if DeJean handles it, the Eagles defense gets even more flexible. And for a defense that already has Quinyon Mitchell, Jalen Carter, and a coordinator who loves making quarterbacks uncomfortable, that is a pretty good place to be.

Cooper DeJean playing safety in base packages is not some random offseason note. It could be one of the more interesting wrinkles in the Eagles defense this year.

And with DeJean, it is probably worth giving Fangio the benefit of the doubt.
