Gotta ask. Doesn't Pittsburgh hold a tie-breaker over the stinkin' Ravens even if they lose? Wait, I have the rules now.... just looking  and it would come down to best record in common games due to the fact that our division records would be identical ...So, aside taking away our division games, our common opponents are these:

Tennessee

Indianapolis

Houston

New York Giants

Philapelphia

Washington

Dallas

Jax

To date, Baltimore is 3-3  with Dallas and Jax to go.

We are 4-3 with only Tennessee to go.  So, if we lose to Baltimore and then win out (assuming that Tenn has nothing to play for),  and Baltimore also wins out, we both end up 5-3 against common opponents.  But we win the tiebreaker, because the tie-breaker must then shift to conference record!  Baltimore  has already lost an extra conference game (Tennessee). 

If we gotta lose to Baltimore (perish the thought!) then this is the time to do it.  A Pittsburgh loss to Baltimore gives Tennessee home field throughout the playoffs and takes away much of their motivation to play bruiseball with the Steelers.
