The Blues, 21-13-7 on the road during the regular season, continued to play well away from Enterprise Center by going 10-3 as visitors in the playoffs, but they saved their best road performances for the Final.
They won three of four games at TD Garden, including Game 7, and even after a demoralizing 5-1 loss at home in Game 6 when they could have clinched the Cup in front of their fans, St. Louis was confident it could win the Cup on the road.
"We played our style on the road," center Tyler Bozak said. "It's not pretty, but it gets the job done."
The Blues outscored the Bruins 11-8 in Boston.
"Maybe taking a more simpler approach more than anything," Blues coach Craig Berube said. "I think when you're at home, you're maybe trying to play a little differently at times. On the road, more of a simpler approach, I think, directness, predictable probably has a lot to do with it. We've just been a good road team for a long time. We feel pretty comfortable on the road."
