ESPN's NFL Live Top 3 NFC teams

I'd put Dallas at #1 as well.

The Seahawks to me still aren't a top-tier team. Last year was last year. They'll probably have to win two road games to get to the Super Bowl, and they don't scare anybody on the road. While I don't think there's any real justification for putting them higher than the Saints, based on the way the two teams have played this year (even accounting for the injuries to Hasselbeck and Alexander), you can certainly see how people would give the defending NFC champs the benefit of the doubt. Still, if a 10-point win at home against Green Bay is a measuring stick, I'm not all that impressed myself.
With the Bears, they're a clear #2. People can rag on Grossman all they want, but they're 9-2, they have a terrific defense, and will probably have two home playoff games in January, which they will have earned. My sense is that your best bet is to catch them not in game 1, but in game 2, and hope that's the game Grossman plays less well and you get your chances to steal it.
