NOTES:
Cards win and in, lose and out.
Rams in with win or with Packers win.
1st most likely outcome - Seahawks 3 seed and 1st game Rams@Seattle.
2nd most likely outcome - Seahawks 3 seed and 1st game Cards@Seattle.
Pretty slim odds for Seahawks 1 seed.
Not a bad chance for 2 seed, then most likely Bears@Seattle.
Cards win + Packers win = 3 NFC West teams in playoffs.
With the Packers/Bears game being the most decisive, it will probably flex to SNF. Therefore, the Seahawks "should" be playing to win against the 49ers since a chance at a better seed will be on the line.
