Update on playoff scenarios for Seahawks

With Detroit and Dallas leading by wide margins, the Seattle Seahawks' playoff chances are flickering.

The team would need to come back from a 16-10 deficit to beat San Francisco, then defeat Arizona in Week 17. Chicago would have to win its final two games. Atlanta would have to lose its final two games.

That would produce a three-way tie for the wild-card berth, and Seattle would prevail on a tiebreaker.

Thanks to Jeremy Mills of ESPN Stats & Information for helping with the scenarios. He's grinding through all of them for all playoff-eligible teams in the league. Seattle just blocked a punt and will take over deep in 49ers territory.

Note: Seattle just took the lead.
