This is a surprise for sure. I expected the Eagles, as SB champs, to start the season, but against the Cowboys? That's a surprise.
The Cowboys are at a disadvantage for sure. The Cowboys have new coaches on offense and defense and since they don't play their starters in pre-season, it is unlikely they will have their ducks together for opening day.
But my expectation is that the Eagles will win the division again and Dallas will finish 3rd or 4th so it doesn't really matter when they play the Eagles.
