"We just have to be disciplined and stay the same way."
A penalty turned the tide in Game 5. New York forward Brian Boyle was called for a retaliation penalty in the second period as the Rangers were protecting a 1-0 lead.
The Capitals' potent power play took advantage to tie it. It stayed even until Mike Ribeiro won it at 9:24 of overtime with his first goal of the series.
"You battle so hard through the regular season to try to get the home-ice advantage in case there is a Game 7," Brouwer said. "You'd like to have the home crowd and the home familiarity, your own bed the night before as an advantage, but I think all these games have just been so close.
"It's just the way they've gone. I don't think it's because one team is better at home than they are on the road. Everyone is playing good hockey right now, and it's been an exciting series to play in."

The Rangers are looking for a breakout from forwards Rick Nash and Brad Richards. Both have one point through five games: Richards with a goal, and Nash with an assist.

Rangers coach John Tortorella didn't even want to address the notion that it could be his club's final game of the season.
"I don't consider it an elimination game," he said. "We're trying to win one game. I'm not going to even use that word. We've bounced back. Guys that haven't been in it, it's an opportunity. That's the way they have to look at it. We'll go home and try to win a game."
The Rangers might again be without rugged forward Ryane Clowe, who was injured earlier in the series and returned for Game 5 on Friday. Another hit has knocked him to the sidelines again. He and fellow injured forward Daroll Powe, who like Clowe might have a concussion, didn't skate Saturday.
Chris Kreider and Kris Newbury are potential replacements for Clowe.
New York defenseman Marc Staal, who came back from a serious eye injury in Game 3, hasn't played in either of the past two games and isn't expected back Sunday. either.
