"It's frustrating," Chicago defenseman Duncan Keith said. "We just need to go out and play and let our skill take over."
They've had a tough time against Rask, just as the Toronto Maple Leafs, the New York Rangers and Pittsburgh Penguins did in the Bruins previous three series.
Rask has stopped 61 of 62 shots in the last two games and 120 of 125 in the series.
Bruins coach Claude Julien didn't find out his team wouldn't have to deal with Hossa until just before the game.
"I was surprised as anybody else," he said, "but, to be honest with you, there weren't any changes in our game. As I mentioned the other day when I was asked about another player, we don't make our game plan based on an individual.
"I can definitely tell you they lost a pretty important player on their roster, but that doesn't mean we change our game. I think it's important we stick with what we believe in."
They believe the key to winning in the playoffs is disciplined and persistent checking, precise passing and steady, if not spectacular, goaltending.
They Blackhawks have been stymied by all of that.
"It's a low-chance game. It's a low-chance series," Quenneville said. "It's hard to get A-plus chances. You have to manufacture the second, kind of ugly goals, tip screens, deflections."
That's tough to do.
Without Hossa, it's even tougher.
