Power Rankings: No. 19 Philadelphia Eagles

A weekly examination of the Eagles’ ESPN Power Rankings:

Preseason: 25 | Last Week: 14 | ESPN.com Power Ranking since 2002

There’s naturally a lot of movement in the early part of the season, as preseason expectations crash headlong into reality.

So it wasn’t a surprise when the Eagles made the biggest jump in ESPN’s Power Rankings last week, from No. 25 to No. 14. And it’s not a surprise that they slid back to No. 19 after Chip Kelly’s first NFL loss Sunday, a 33-30 decision to the San Diego Chargers.

The Eagles have yo-yo’d more than most because the preseason expectations were so difficult to pin down. They were a 4-12 team last year with an enigmatic new coach with no NFL experience. When they made that dazzling “Monday Night Football” debut, the Eagles gave ESPN’s experts good reason to place them in the middle of the NFL pack.

Now that we’ve seen the cracks in the Eagles’ foundation -- namely, the second-worst pass defense in the NFL -- it seems fair to place them behind NFC East rival Dallas (15) and ahead of winless Washington (24) and New York (20). With a game against Andy Reid’s Kansas City Chiefs on Thursday night, the yo-yo is likely to change positions again next Tuesday.
