NFL power rankings: Eagles, Patriots still on top heading into Week 1

The NFL's 2018 regular season is nigh. However the preseason has produced a few curveballs when it comes to assessing the league's overall power structure.
A look at how all 32 teams stack up heading into Week 1.

1. Eagles: Nope, Carson Wentz isn't ready. Yup, preseason a mess for Nick Foles and depleted offense.
But champs retain our top spot until first loss.

2. Patriots: Significant questions at left tackle, wide receiver and defense for AFC's kings. But can't take them lightly as long as TB12 is slinging.

3. Falcons: Fresh measuring stick for talented squad comes Thursday night, nearly eight months after its five-point playoff loss in Philadelphia.

4. Rams: They're loaded on both sides of ball. But after keeping so many starters bubble wrapped in August, will they emerge firing on all cylinders?

5. Saints: With five of first six games against teams that failed to reach postseason last year, infamously slow starters should hit ground running.
