Take it from Bill Cowher: The coach with a 1-4 home record in AFC championship games has a few pieces of advice for Mike Tomlin's Steelers.

Don't relax.

Don't rest on regular-season precedence.

"The one thing you have to be very careful about is thinking, 'OK, we're playing at home. We beat this team twice. And we'll beat them again, because our fans will be there,'" Cowher cautioned earlier this week, in advance of his gig as a studio analyst on CBS's "NFL Today" before the Steelers-Ravens title bout.

"You have to be very careful. The one thing about the playoffs, it isn't about your strengths. The playoffs will expose any weakness you have. The one thing I've seen about Baltimore, they will not beat themselves. I can see them doing the same thing here: Play very close to the [vest] early, keep the defense in it and try to make a play late. It's going to be a very physical game, and there's going to be a lot of emotion. You've got to kind of temper that."

The Steelers under Cowher in 1994 lost to San Diego in San Diego and 22 days later dropped a woebegone championship game to the Chargers at Three Rivers Stadium. His 1997 club beat Denver by 11 points in the first week of December, then lost in January also at Three Rivers Stadium. In 2004, they thumped New England at home on Halloween, then were trounced by the Patriots there three months later.

In between at home, they lost to New England in 2001 and beat Indianapolis in 1995, having played neither in those regular seasons.

Beating a team three times in a season? Cowher's clubs did it two times: Cleveland in 1994 and 2002 -- the first leg of the victorious road to Super Bowl XL. The Steelers also split with Baltimore in 2001 before winning a divisional playoff that January.

"It is hard," Cowher said. "Particularly when you're talking about two games, where one was decided in overtime and the other one was decided by a play [Santonio Holmes' catch] that went to review and was talked about for a long time, whether it was a touchdown or not. It's not going to be easy. Neither team is going to fool each other.

"You're going to have to have [new] wrinkles in this game. The one thing that's been consistent is, the defense of Baltimore has taken the ball away. If Pittsburgh doesn't protect the football, they're going to be in trouble. But they've done a good job, and Ben [Roethlisberger] may be coming off the best game he's played all season."
