The Philadelphia Eagles struggled on defense in their first game against the Detroit Lions.

They made huge moves this offseason to their defense, moves that should elevate it to one of the league’s best.

With the signing of elite pass rusher Haason Reddick, they instantly got better in that department. Then add in the rookies they were able to steal.

The two former Georgia Bulldogs in Jordan Davis at defensive tackle and Nakobe Dean at linebacker, suit the style of this defense so well.

Of course, they also were able to finesse the New Orleans Saints for Chauncey Gardner-Johnson. He has Philly written all over him and is someone that has the talent and skill to make big plays.

However, even with all of those moves, they still gave up 35 points to a Detroit Lions team that is, well, bad.

So what happened?

“A lot of it came down to situational ball because we had our chances to get off of the field a couple of times and we didn’t do it,” Eagles defensive coordinator Jonathan Gannon told the media on Tuesday.

“We were getting it to third down a good amount, I think the one drive they had five third downs they converted. You know, you are just going down a long hard road if you are not getting off of the field on third down, and that extends drives, and then you get into the red zone, and we didn’t hold up in the red zone, and those are points.

“It’s really a combination of, first and second down doing what we are doing, but then executing a little bit better on third down to make them punt… so like I said, we got to get it cleaned up and we will get it cleaned up.”

And that all makes sense. The Lions were 9-14 on third down, and 1-1 on fourth down. Against a team like the Lions, that is awful, and it simply won’t cut it.

Yes, there were some good things that happened on the defensive side of the ball, like the pick-six by James Bradberry, and the tip by Kyzir White that led to the interception.

The run game has to be better, especially in critical situations like third and fourth downs. This Lions team is not good enough to continually drive the ball down the Eagles’ throats. But, they did.

If the Lions can do it, I know for a fact that the other teams the Eagles play can do it too, only they will be better. It definitely needs to be fixed.
