There's a very small chance yet one more game could be played there. Niners are the fifth seed right now. If they win out, they could host the sixth seed for the NFC championship, if the sixth seed could get there. That looks to be the Saints right now.
Highly unlikely... But (in my best Berman voice) that's why they play the game...
How likely was it that the Cardinals would beat the Seahawks today? While it’s very unlikely, the 49ers could still win the NFC West. Go Niners.
