The No. 1 spot in the NFC was clinched by the Seahawks last night, but spots 2-6 are still up for grabs, with the Packers locked into the seventh spot. As for the AFC, pretty much every spot is available, with all likelihood that the Broncos clinch the 1 seed with a win over the Chargers, who are resting their players.
