Meeting with the media prior to the Olympic break, Bruins general manager Peter Chiarelli said he would like to add defensive depth before the March 5 deadline.

The perceived need for the Bruins would be a top-4 defenseman, as the team will be without Dennis Seidenberg for the rest of the season. Chiarelli didn’t say whether he would want a lefty for the second pair or a righty to play in Seidenberg’s usual postseason spot alongside Zdeno Chara.

“I want a little more defending and if a guy can play both sides that would be great,” Chiarelli said. “We’€™re not going to replace Seids. I want the ability to defend; I want a little bit of heaviness.”

If the Bruins are unable to find somebody, Chiarelli said he would be comfortable with Matt Bartkowski remaining as his second left-side blueliner.

“Yeah, I would be,” Chiarelli said. “He’€™s learning, he’€™s learning better how to defend, he’€™s getting a little more minutes. He’€™s still making mistakes but the rest of them are too. I’€™ve been looking closely at his defending, he certainly can wheel the puck out well and turn the net well but he’€™s maturing as a defender. That’€™s what we’€™re looking for, better defenders.”
