I'm just speculating here, and that's all this is. Not a disagreement.
Per your comment. "Eagles are the class of the NFC, period."
It certainly looks that way right now, but now is just a moment in time.
Although I'm not predicting it, what if the Eagles lose their next two on the road to the Seahawks and Rams?
It's certainly possible. Home field is an advantage. Witness the Rams @Vikes vs home against Saints.
Are the Eagles then still so clearly the class of the NFC?
I believe that has not been determined quite yet.
Ramily!
