Yes, teams lose. Half of them lose every Sunday. That's not the point.
Rams loss (wasnt this week) was 26-23 OT loss against a division rival. The Lions lost at home to the Vikes 27-24. Not a blow out. I can handle a close, hard fought loss against a division opponent. Both the 9ers and Vikings are talented playoff teams.
Packers lost 16-13, and it was 7-6 at the half, again, close, hard fought game.
None of the games you mention were blow outs where the clearly better team just failed to show up across all 3 phases against a weak and feeble division rival.
