We're in. You can see above it's 99% for playoffs. Which means we have to lose every game, and some people have to win the right games, if we're not going to slip in even at #7.
As others wrote, I think we're almost guaranteed that #5 spot. It's more about where the other opponents fall if we feel that it will give an advantageous bracket.
Which I believe in, because I can't honestly say with 100% confidence that 95 Super Bowl team would have won without GB's help knocking off SF in the Playoffs.
