According to the Boston Herald, Chiarelli plans on playing things out and seeing how his team responds before making any hasty decisions.
"We're going to look from within and see how it works out," Chiarelli told the paper. "We'll see how the group comes together. After that I'll make an assessment on whether we need to add somebody. If you're asking me if something is going to happen in a week? No. Two weeks? No. I haven't made any calls; I haven't delved into that yet. I know who's available just from making my routine calls over the course of time. There's a fair amount (of defensemen) available. Nothing is perfect. You're not going to replace Dennis.
"If I'm not satisfied with how the group is defensively, then I would look. But we're still two, three, four weeks away from that, at least. In short, I don't like the looseness. I understand it's a long year and we've got to work our way through this stuff. I would just hope we get a little tighter defensively."
A number of defenseman are available, as Chiarelli pointed out, and more should hit the market in a month's time.
The Bruins could target someone like Dan Girardi of the New York Rangers, who is set to become an unrestricted free agent this summer and a player the Rangers have been entertaining calls for.
