In 48 hours, the Bruins went from one extreme to another.

At the Garden on Thursday, the B's were uncharacteristically sloppy and far too loose defensively, dropping a run-and-gun game of shinny, 7-4, to the Buffalo Sabres.

But at Toronto's Air Canada Centre on Saturday night, the Bruins rediscovered their true identity — clamping down on the Maple Leafs with 60 minutes of sound team defense in a 1-0 victory.

"It was a good, tight game," Bruins center Gregory Campbell said. "Those conditions are conditions that we're good in.

"Those 1-0 games seem to happen quite often these days. Winning those is something we take a lot of pride in. We're working hard offensively; the chances will come and the goals will come. But more importantly what we have to take from this game is that we were pretty solid defensively."

The Bruins would love a repeat of Saturday's performance when they go back to work on Wednesday night in Montreal against the Canadiens, who are off to a fine start (6-2-0) and promise to be a tough opponent this season.

The B's got a day off yesterday and resume practice today. More will be known then about the status of winger Brad Marchand, who was banged up (left shoulder?) crashing into the end boards in Toronto and missed the third period in what coach Claude Julien assured was merely a precautionary move.

Also, winger Daniel Paille, assuming his problem is nothing more than a cut under his left eye, should be ready to go.

The win was the B's seventh in succession against the Maple Leafs. Another trend that continued: the smothering and frustrating of Phil Kessel. As fast and talented as he is, Kessel has accomplished little against his former team. In 19 games, he has 3-6-9 totals and a minus-18 rating.
