the only real angle or edge I see here for the Seahawks, is an extension of their home field advantage. The Saints in recent years have not played up to their true form, in outdoor venues, especially in colder weather. Weather isn't nearly as cold as I hoped it would be for todays game. but still somthing to think about.
also, the Seahawks, have nothing to lose here. They know they are huge underdogs, and want to shock the world. They've been given a gift birth essentially in this single elimination tourney, and they'll play loose with it....
