Call it spin or creative marketing.

But Bruins general manager Peter Chiarelli, while admitting frustration in not landing one of eight snipers they hoped to add before Wednesday’s trading deadline, did say the Bruins accomplished something significant that indirectly could result in a better offense.

In making two deadline-day trades while shipping one of their current defenseman and a forward out of town, they remade their blue line. The centerpiece is 28-year-old defenseman Dennis Seidenberg, a defenseman aquired from Florida, along with the rights to Ohio State defenseman Matt Bartkowski, in exchange for forward Byron Bitz, Craig Weller and a second-round draft pick in this year’s draft.

“I know a lot of the questions will be, ‘Why didn’t we get scoring?’ And those are very good and valid questions. Firstly, we wanted to change the composition of our defense. I can say that was an equal priority to getting some more scoring,” Chiarelli said.

Earlier Wednesday, the Bruins sent 31-year-old defenseman Derek Morris to Phoenix for a conditional pick in the 2011 draft. On Tuesday, the Bruins added defensemen Cody Wild from Edmonton and the rights to University of Michigan defenseman Steve Kampfer from Anaheim.

“I put [defense] as an equal priority because I feel that if we change the composition that will, in itself, allow us to improve from the backend out and that should result in better offensive production,” Chiarelli said. “It allows defensemen to play in their appropriate roles and that was the motivation behind that now.”

Chiarelli said he and his staff targeted eight potential forwards around the NHL as possible acquisitions prior to the deadline but he deemed the asking price too high. Names such as Edmonton’s Steve Staios, Raffi Torres, who wound up being traded from Columbus to Buffalo and Carolina’s Ray Whitney, who wasn’t dealt at all, were among the names rumored to be on Boston’s radar.

“With regard to improving the scoring, there were some players out there and we were in on more than a couple,” Chiarelli said. “But I guess at the end of the day, I just wasn’t in a position to give what they wanted. I didn’t think additions that I contemplated would produce more than marginal improvement. Hard to believe after scoring one goal [Tuesday] night, I really believe our group can score more and we will score more.”
