I think, and don’t quote me because the computer runs 67 million scenarios so I can’t pencil out each one to find it, but I think if the Rams win the NFC West (which the Packers beat) then there could theorectically be a party at 11-6 that the Packers could lose the tiebreaker on. I think (same caveat) that is the only way an 11-6 Packers team could miss out, if the Rams win the West.
But, realistically, an 11-6 Packers team would go to the playoffs.
Yeah, it’s a tricky one that isn’t likely.
