12-4 is still very likely barring no major injuries. This is assuming they get their crap together and beat the Niners.
After next week their schedule softens with losing teams like the Bengals, Falcons, Steelers, and Cards up next.. Then the next two tough games they have are home against the Ravens and Bears... Two teams that don't pass it well.
Then you finish up with Dallas away Seattle Home, Niners away and Cards Home.
I see maybe two more losses max, out of the remaining 5 quality opponents. (Dallas, Seattle, Bears, Ravens, Niners away)
Key will be to not cough up a game that you are heavy favorites in against the Steelers or Falcons away.
