​The Eagles' are elite when rushing the passer, but if that passer gets the chance to throw, bad things happen. Bad, bad things. Philadelphia's pass defense is atrocious.

Stop me if you've heard this one before. The Eagles were torched by the opposing quarterback in their 23-21 loss to the Vikings on Sunday. 

Kirk Cousins completed 30 passes for 301 yards and one touchdown. While these aren't ridiculous numbers, their pretty high for a defense that considers themselves elite. This isn't just a fluke. The Eagles have given up over 250 passing yards four times this season. There's only been five games. 

The Eagles' pass rush continues to be dominant with 11 sacks on the season, but their pass defense has only caused three interceptions. They're lacking talent in the secondary. ​Cornerbacks Ronald Darby and Jalen Mills have been exposed by receivers all year

After the loss of star safety Rodney McLeod to a knee injury in Week 3, ​​the team is starting to show that ​they're pretty thin in secondary depth. Teams are starting to realize that they can go deep on Philadelphia, and playing catch-up won't work all season.
