Here's why I wouldn't worry about the Eagles too much (who I thought would be good early in the season):
1. There's no way that team can keep that pace for 16 weeks. Other teams only have to do it once (twice for divisional opponents). The Eagles are going to do that EVERY week, which means a LOT more plays on their offense AND defense, and much more chance of sustaining injuries, not only because of volume of plays but fatigue as well. Tired players get hurt.
2. The Commanders offense was putrid last night. They handed Philly the game early, and RG3 was awful. He wasn't ready to play.
3. The Eagles only scored one touchdown the second half.
4. Vick already yanked a groin and took some shots last night. He looked like a tired, old man late in that game, and this is only Week 1.
5. Film. Teams will get a better handle on them with a few games of film on them. And that speed they showed will slow down as the season wears on. I don't see Vick and McCoy finishing this season healthy at all. Both could be out by midseason, and Foles can't do this.
6. That's a bad Eagles defense, so no matter how many points they score, they will always be in danger of losing.
Lastly, I think Chip Kellly knows how to stop the read option, which is partly why the Eagle defense was successful early. Teams could take that and turn it against the 49ers, Seahawks, and Commanders. Thanks, Chip, for that.
