The Eagles will finish the season without another loss. Pittsburgh was a wake-up call, and they altered their defensive personel as a result.
The only team in the NFC who can give them any trouble is Atlanta, since it's very hard to stop Vick.
This is the first year that McNabb has had the tools on offense to score. He's never have a decent wide-out and now he has the best. That's the reason the Eagles are 10-1. T.O. has put them over the top. The only team that can score with them is Indianapolis. He's always had a running back, and a decent tight end, but no-one to stretch the field.
I'm not worried about the Eagles loosing until they get to the Super Bowl. They will face either Pittsbugh, New England or Indy, and right now, I'm giving the nod to Pittsburgh.
Keep in mind that when the Eagles lost to Pittsburgh, they didn't have Westbrook, and Trotter was not in the starting lineup. The Eagles also had injuries on their offensive line, that they hadn't addressed properly.
I expect a Pittsburgh/ Philly Super Bowl, with the Eagles defense able to stop the Stealers from controlling the clock. Their defense will break down as the game goes on, and McNabb will find a way to win in the end.
