Nah, this is a dream scenario as is for the Seahawks...all metrics/simulations had them as likely victors today as it was. Now they've been spotted 8 points, only had to have their league best defense on the field for 6 first quarter snaps, and have worn down the Denver D a ton in a short period of time, and now they get the ball again in great field position.
If they play their game and don't shoot themselves in the foot with turnovers of their own, it's gonna be tough for them to lose this game....statistically, Seattle is a virtual lock to win atm.
Manning will have his moments, but he simply won't be able to go gang busters on a D this good that is so well rested....particularly when they're gonna have to shelf the run game here before long, (making Seattle pass defence job, all that much easier)
