The unit that was supposed to be some dominant against the pass has failed through the first five games. The Eagles defensive backs have just two interceptions so far and have struggled to make tackles and key stops when the defense really needs it.
Most of the blame has to go to defensive coordinator Juan Castillo, who has used Nnamdi Asomugha in every way except as a press man cover corner this season. Asomugha has looked very mediocre and has already given up more touchdowns than he did all of last year with the Oakland Raiders.
The safeties have also really struggled. Nate Allen is finally healthy and should solidify this group a little bit. The strong safety spot has really struggled. Jarrad Page was replaced against Buffalo by formerly bench free safety Kurt Coleman. No matter who is playing opposite of Nate Allen, it doesn't really matter because no one is getting the job done in run support or against the pass.
Overall, this group has enough talent to get the job done. It's just a matter of putting the players in the right position. Castillo appears to be learning on the job much like a trainee at a local restaurant. Until Castillo can figure out how to properly position his defensive backs on defense to make plays, this until will continue to overachieve this season.
If he figures it out, however, this defense is capable of making a lot of plays and giving the offense a chance to starting winning again. The question is, will Andy Reid and Juan Castillo have more than one more game to prove they can get it done?
