Wins aren't just hard to come by on the road, but points, too.
The Ravens only scored three field goals in an ugly, 9-6 victory at the Kansas City Chiefs two weeks ago. That marked six consecutive quarters in which they've failed to score a touchdown away from home this season.
"It's definitely a priority to get out and start fast, definitely on the road. The number one goal is to win. That's been pretty tough this year is to win on the road," running back Ray Rice said. "The way our offense wants to be, the way we want to play is with the tempo. So we like to get out and try to start fast."
The Ravens' no-huddle offense has been hot and cold. They haven't scored a touchdown in the first quarter in four consecutive games, including at home.
"We would prefer to come out and make a good first impression," Ravens coach John Harbaugh said. "We haven't always done that."
Houston has never beaten Baltimore in five tries, including a 29-14 regular season loss last season and 20-13 in the playoffs. But the Texans are off to their best start in franchise history.
"It is sort of like that Pittsburgh Steeler-feeling kind of game. … Wow they've arrived. It's the best start in franchise history. They've earned it," Rice said. "They've earned the respect from the rest of the NFL.
"Nobody's looking at the Houston Texans on their schedule no more and saying, 'Oh shoot we got an easy game.' They're looking at the Houston Texans knowing you're going in for a fight."
Harbaugh expects Reliant Stadium to be a difficult venue to for his Ravens to succeed.
"It seems like we're a team that people get excited to play against, crowds get pumped up for us when we come in there it seems like," he said. "We usually get the best of the crowd."
