The Pittsburgh Steelers showed their playoff mettle on Sunday.
The Steelers defeated the Baltimore Ravens behind backup quarterback Charlie Batch for their most impressive road win since they won in Baltimore in 2010.
A 2012 NFL playoff berth is well within the Steelers' reach. Three of their final four games are at home, and there's a strong possibility they'll have Ben Roethlisberger back for all of them. The only team left on Pittsburgh's schedule with a winning record is the Cincinnati Bengals, who they've already defeated this season.
The Steelers (7-5) better enjoy being home for Christmas and sleeping in their own beds in December, because if they make the playoffs, they're likely to hit the road.
They can't guarantee home-field advantage throughout the playoffs because they're out of the running for the No. 1 seed. There's a slim chance they could be the second, third or fourth seed. It would require overtaking the Ravens (9-3) and winning the AFC North.
Chances are the Steelers will be the No. 5 or No. 6 seed if they make the postseason.
That might not be a bad thing.
In the franchise's 23 playoff appearances since teams were first seeded in 1975, the Steelers have held each of the six seeds at least twice. With the help of Pro Football Reference, let's take a look at how the Steelers have fared historically as each seed.
