So if the Steelers lose, they're probably OUT OF THE PLAYOFFS
A loss would put them at 8-6-1.
Best possible record would be 9-6-1.
The Ravens are home against the Browns next week; a win would put them at 10-6, division winner.
As for the second wild card spot, the Titans and Colts are both 9-6 and play head to head final game. One team will win and be 10-6, ahead of the Steelers. If they lose, they'd need a very unlikely Ravens loss, or an astronomically unlikely Titans-Colts tie, or they are OUT! As for that astronomically unlikely tie, if that game went to OT, a tiebreaker would go to the Steelers, so both the Titans and Colts would eliminate themselves with a tie. It isn't happening.
