Even if the 49ers lose to Seattle and we beat the Cardinals, we would be tied in the head-to-head matchup (1-1) and tied in the division (4-2). The last tie-breaker would be conference record which the whiners take in a landslide (9-3 vs 7-5).
We are locked into the 6th seed.
Rams would be 5th seed if they win and Niners lose.
