"Obviously we have a lot of cap room, so there's a lot of flexibility," Chiarelli told ESPN.com. "I would like to add depth-wise on the forward front and depth-wise on the defenseman front. But I don't want to subtract anything."
Last season, Chiarelli made several significant changes, adding forwards Rich Peverley and Chris Kelly and defenseman Tomas Kaberle before the deadline en route to a Stanley Cup championship.
"The difference between last year and this year is that I'm a little more certain about the chemistry at this point," said the Bruins GM. "So I have to be a little more careful about adding. I don't want to subtract in order to add. If I can add, I want to be careful about chemistry."
Chiarelli refused to name potential targets, but many believe he could be looking at Carolina Hurricanes forward Tuomo Ruutu and/or blueliner Tim Gleason. Both are set to become unrestricted free agents this summer.
