I don't want to look too far into the crystal ball, but if Pittsburgh gets back to the Super Bowl, here's who they might end up facing and a brief snapshot of that matchup:
Green Bay Packers
A rematch of Super Bowl XLV would be interesting, especially given Pittsburgh willingness to throw the ball and Green Bay's awful pass defense. Still, this is a nightmare game for Pittsburgh's defense in some ways, but a game that could be won even if it became a shootout.
New Orleans Saints
I'd say the Saints are a more likely Super Bowl team than San Francisco because of their offense, but New Orleans would have a difficult time stopping the Pittsburgh offense with the weak play at corner they've been getting. Still, the Saints offense would make this a track meet unless the Steelers could run a lot of long drives.
San Francisco 49ers
We'll get a look at these two teams in Week 15, but the Steelers are a great matchup for San Francisco. The 49ers offense is predicated on running the ball, something Pittsburgh can stop.
Their defense is good, but they haven't really faced an offense like Pittsburgh's this season and would have to face the two teams above if they hoped to get to Indianapolis.
The common thread with each of the potential Super Bowl matchups is that the Steelers have the potential to carry out long drives to keep the most dangerous components of their opponent on the bench. The most difficult team to do this against would be San Francisco given their defense, but the 49ers offense would be hard-pressed to keep up with a fast-attacking Pittsburgh team.
