Anyone expecting the Bruins to trample over Montreal as they did in the Canadiens' last two trips to the Garden had a very cold bucket of reality dumped on them last night. In Game 1 of the Eastern Conference quarterfinals on Causeway Street, the Canadiens scored in the opening minutes and then added a late goal for a 2-0 victory against the Bruins and a 1-0 lead in the best-of-seven series. The B's worked for 82 games to earn home-ice advantage in this series, and now it's in the hands of the Canadiens. Brian Gionta scored the Montreal goals, both coming on defensive-zone turnovers by the Bruins. Carey Price stopped all 31 shots the hosts threw at him. The Bruins at times dominated territorially, especially in the second period when they outshot the Habs 18-6, but they didn't make Price's job hard enough. He posted his third playoff shutout, all of which have come at the Bruins' expense.
