It was a complete team loss. It was an "F" on the letter grade scale. There were very few, if any, bright spots.
The Eagles had an opportunity to make a huge positive statement with this game but completely failed to do it. Instead, they leave Lambeau with a crushing loss and a big negative statement. That statement being: the Philadelphia Eagles are who we thought they were.
In their loss to the Packers, Philadelphia proved to be the team people expected the Eagles to be heading into the season. They were a flawed team with an ineffective pass rush and an exposed secondary. They were an offense without a sure answer at that quarterback position.
The Eagles were not the team who they had been (or the team who the fans wanted them to be) in the past few games. That was a team that could generate a pass rush and hold their own in coverage. That was also a team that didn't look outmatched when you compared Philadelphia's quarterback to their opponent's starter.
The bad news for Philadelphia is that there's nothing they can do to erase this loss. There are real flaws with this team (see: secondary, quarterback) that aren't magically going to go away. As far as this game is concerned, the Eagles will just have to accept that they were out-classed by the better team.
The good news for the Eagles is that they don't need to let this loss define their season. They do have a chance to rebound given the fact they play a lowly Tennessee Titans team next.
For now, it's a tough loss for the Birds. And it's one the whole team shares equally.
