I think the Packers and Dallas both have the ability to play with Seattle. The reason is their ability to effectively throw downfield effectively. You have to be able to do that against them. If you just throw short all day, their big DB's will pummel you. Both teams can run enough to make Seattle respect play-action, both have offensive lines good enough to give their QB time, both have a top deep threat, both havea QB who can throw deep and move around enough to buy time. Dallas already did beat Seattle this year. However, if the Packers end up the #2 seed, and Dallas #3, the Packers and Dallas would meet in the divisional round.
