Eagles O-Line play was phen. last week. However, do keep it mind that Panthers and Fox were very conservative in their play calling, deciding not to blitz much of the game. That should be the main concern for the Eagles backers, in addition to the starting QB controversy.
On that note, it will be very interesting to see if McNabb plays. I would think, after seeing the injury and what injuries he has played through in the past, that he will be on the field on Sunday. If that is the case, look for this line to go to 2.5 -4.0 with the Eagles being the odds on favorites.
Keep in mind the following trend:
Eagles are 7-1 over last 8 against Saints
