Hard to imagine the Eagles losing, but on the lther hand, last year the Commanders beat the Eagles in Philadelphia, and they had no business winning that game, either.
Anybody remember that one? The Commanders just ground it out as slowly as they possibly could, taking as much time off the clock as they could on every play, and kept the Eagles offense off the field for something like 75 or 80% of the game.
I don't think they have the offensive line required to play that sort of grind it out game this year. A 21-point loss wouldn't surprise me in the least.
