I'm confused by the Seahawk support... I really like the Eagles to take this game and like the current PHI -3 (+110) available.
Looking at the Seahawks, they really don't have much available on the ground. Lynch gets the majority of the carries, but he's more of a power back than a speed/agility guy that's more suited to be a #2 RB. In the air, Tavaris Jackson is one of the worst starting QBs in the NFL. Additionally, Sidney Rice will almost definitely not play this week as he just suffered another concussion on Sunday. The short week will keep him out of the lineup, IMO. Their defense looks good on paper, but when you consider who they've faced, their "solid D" makes more sense. They really only have one win against a quality team this season and that was against a Baltimore team who were themselves coming off the most important game of their season (which virtually guaranteed them the AFC North division win).
People make WAY too much of the loss to the Patriots. New England has hit their stride and are a much superior team to the current Philly team. A lot of much better teams that the Eagles have been picked apart by Tom Brady. It shouldn't be viewed as an unexpected loss, and shouldn't detract from the matchup issues for this game. Philadelphia is a much better team than the Seahawks and presents matchup issues that will make this a tough game for Seattle to be competitive.
Specifically, Tavaris Jackson will get sacked no less than 4 times in this game. Short on receiving options and range while facing a depleted (but still quality) PHI secondary is going to expand the time he'll need to work, while being harried by an aggressive Eagles pass rush. Philadelphia is one of the best teams at bringing pressure and I really don't consider Lynch to be sufficiently dangerous that he'll be able to take advantage of the spacing of the wide 9 in the interior. Philadelphia will prioritize applying pressure to Jackson to help out their depleted secondary, and Seattle is vulnerable to sacks (particularly from pressure coming off the ends and corner blitzes)
On the other end, Vince Young has another game under his belt and looked pretty good early on against the Patriots. His completion rate is low for that game because the Eagles had to pass a lot when trailing in the game. He was only sacked twice, but pressured a lot in that game and still managed 400 yards. Seattle is very weak in their pass rush and VY is going to have the time to work. The one element that Seattle is very good at is run defense, but McCoy is extremely versatile and should challenge the Seattle defensive line enough that he will still probably get 70 rushing yards. I would expect him to get a few productive touches receiving out of the backfield as well.
Finally, in the second half of the last game, Andy Reid was taking a lot of abuse from the Philadelphia "faithful" and the one element about this team that often goes unmentioned during all the dream team talk, is that Andy Reid is very well respected by his players. This trash talking of Reid is a powerful motivator to this group to perform and given the matchup issues mentioned above, I expect Philly to win this game soundly. Something in the 24-10 range.
