The Ravens offense hasn't played a complete game away from M&T Bank Stadium.
But will Baltimore's road woes not apply in Pittsburgh?
That's what quarterback Joe Flacco seemed to imply after Sunday's offensive breakout against Oakland.
"I've got to tell you, we've played some big games on the road every year we've been here and we've won a lot of them," Flacco said.
"Obviously, for whatever reason, we're not as successful on a consistent basis. But when it matters, we play very well no matter where we are."
The Ravens' franchise-high, 55-point effort against Oakland underscored the discrepancy between home and road performances this season. Baltimore is now averaging 36.8 points at home and 17.5 on the road.
But Flacco has played well at Heinz Field in his last two regular-season trips, both culminating with dagger-like endings.
He threw for 256 yards in Week 4 of 2010 and delivered the game-winning, 18-yard pass to T.J. Houshmandzadeh with 36 seconds remaining. Flacco threw for 300 yards and delivered the game-winning pass to Torrey Smith with 2:16 left.
Harbaugh was asked how much confidence the team can take away from its dramatic wins in Pittsburgh.
"It's a plus," Harbaugh said. "It's something that we know we're capable of doing. It's something that our guys have done before, the guys who were here. It can't be anything other than a positive."
It boils down to the Ravens not feeling an intimidation factor heading into Heinz Field.
"We're excited to go play it – we always are," Harbaugh said. "We respect them, and we love playing against them. I suspect they feel the same way."
