Canucks’ Roberto Luongo stuck it out in Game 3 despite score

Reporting from Boston — When a team is being blown out, as the Vancouver Canucks were in an 8-1 loss to the Boston Bruins on Monday in Game 3 of the Stanley Cup finals, the losing coach often replaces his starting goalie to spare him further indignity.

Vancouver Coach Alain Vigneault made that offer to Roberto Luongo after Boston’s Daniel Paille scored a short-handed goal at 11:38 of the third period.

“Alain asked me when there was about eight minutes left. I said I wanted to stay in,” Luongo said Tuesday. “If I would have known they would have scored three more times, I might have thought about it.”

The eight-goal barrage on 30 shots increased Luongo’s postseason goals-against average from 2.16 to 2.44 and reduced his save percentage from .928 to .919.

“Even though we were losing, 5-1, it was a pretty intense game and I still wanted to be in there,” he said. “They kept putting the pressure on. We started maybe taking our attention away from our game plan, started worrying about physical aspects of the game, which we shouldn’t be doing at this point.”

GMs to meet

NHL general managers will meet Wednesday in Boston. They’re expected to discuss tweaking Rule 48, adopted a year ago to punish lateral and blindside hits in which the head is targeted or is the principal point of contact.

Etc.

In a surprising turnaround, the Bruins have outscored the Canucks on the power play in the finals. Boston is three for 13 (23.1%) and Vancouver is one for 16 (6.3%). The Bruins were five for 61 (8.2%) over the first three rounds and the Canucks were 17 for 60 (28.3%)….Vancouver center Henrik Sedin wasn’t credited with a shot on goal in the first three games. He usually prefers to let twin brother Daniel be the finisher, but he’s taking matters to a bad extreme from the Canucks’ perspective. “I usually don’t take a whole lot myself,” he said, “but I know I’m going to have to shoot.”
