We lost how many one score games? Faced how many teams in a row coming off of a bye? LOst how many of those to 10 win playoff teams? Philly played Dallas very tough in the first matchup, and had a chance to win. Assuming we would have been blown out yesterday is silliness. Zeke out helped, but that line played. Dak sat down early, but even a rusty Romo isn't much of a downgrade, if any. And the Eagles played short-handed as well.
The Eagles are a heck of a lot closer than you're giving them credit for here. Also not being mentioned is that Howie has already locked up virtually EVERY SINGLE player of significance...we aren't losing much, if anything. There's a reason the Eagles are short on cap space...but unlike most teams in that situation, it's actually a damn GOOD reason.
If Wentz corrects the mechanical issues in the off-season, and we have no reason to believe he can't/won't, there's no reason why this Eagles team can't compete for the division as soon as next year. Dallas will be the favorite for sure, but the Eagles will be more than good enough to make them work hard for it.
