Coming off victories over Ottawa and Carolina - the top two teams in the conference - the Bruins played another top opponent on Monday in the Atlantic Division-leading New York Rangers. This time, Boston lost 5-2 in Brian Leetch's first game against his former team.
Leetch played with the Rangers from 1987-2004 before being traded to Toronto.
"I skated around in a fog out there," said Leetch, who had 240 goals and 741 assists in 1,129 games with New York. "Unfortunately it showed and our team played that way, too. It's hard to play a hockey game when your mind is like that."
Brad Boyes scored in the third period for Boston, tying Patrice Bergeron for the team lead with 22 goals. Boyes has six goals and two assists during a six-game points streak.
Atlanta tied a franchise record with its 33rd victory of the season Monday, shutting out Buffalo 5-0. The Thrashers have won 10 of their last 14 games.

Goalie Kari Lehtonen made 20 saves Monday for his second shutout of the season, and Ilya Kovalchuk, Slava Kozlov and Peter Bondra each had a goal and an assist against the Sabres.
"This was the greatest game I have ever been involved in team-wise," Lehtonen said. "We played so well. We scored when we had a chance and did not give them many chances."
Kovalchuk, whose 43 goals are third in the league behind the Rangers' Jaromir Jagr (46) and the Capitals' Alexander Ovechkin (44), has eight goals and eight assists in his last 15 games.
