If the 49ers win the next three games and get help from the Rams can they lock down the NFC West and secure a spot in the playoffs?

No easy task with the schedule ahead! Assuming I’ve done math and applied the NFL tie break rules correctly.

The Rams would have to lose to the cardinals or lose two games to the Browns and Ravens. The 49ers would be in position to lock down the NFC West at home vs. the Seahawks on December 10, 2023. I feel it is more likely the Rams loose one to game to the Ravens the 49ers could be NFC Divisional Champions with a win vs. the Cardinals on December 17th.

Did I miss anything?
