Seattle will win. Denver got their yards but still settled for FG's against vastly inferior defenses. All this talk about Seattle struggling on offense...if they could put up 23 vs a top 3 defense what do you think they will do to the Broncos? +3 would be a gift.
Manning was 32/43, 400 yards and 2 tds against your D. I wouldn't go too far in to using their settling for field goals as evidence that their offense can't score against Seattle, lol. Those are crazy numbers.
