"I don't think I'll be able to describe what it's going to be like," O'Reilly said. "But from what I've seen, I've been very impressed. And we're excited to get home to show what this town's about.
"This is a hockey town and they've been with us through the ups and downs and they're so excited. It's just something new and special and they're a part of it. It's a big piece of it."
Harnessing the energy and enthusiasm that's expected Saturday will be important, but Blues coach Craig Berube added a note of caution for what's to come.
He's concerned that the Blues took five minor penalties in each of the first two games of the series, and the Bruins went 1-for-5 in each game on the power play.
"We're going to have energy, but we've got to make sure we keep our emotions in check, too," Berube said. "That's a big thing. We don't want to be going to the penalty box and being overemotional about things. We've got to keep them in check and be pretty even-keeled out there, but at the same time have emotion in your game but keep it at a good level."
Soaking up the expected buzz of the home crowds is certain to be a factor in Games 3 and 4, Berube said.
St. Louis is 5-3 at home in the playoffs since losing its first two games in the first round. Each of their three series-clinching wins has come at Enterprise Center.
"I'm excited, for sure," Berube said. "Our whole team is, definitely. The fans have been great here. It's been a good run here so far and we've had great support from our fans and the crowd's been awesome during the games. It'll be a good atmosphere, so we've got to be ready.
"It's going to be a tough game, obviously. Boston's a great team. We just got to be ready to go."
