After what was looking like a very quiet trade deadline, the Bruins did indeed pull of a pair of trades, landing the likes of Greg Zanon, Mike Mottau and Brian Rolston . According to capgeek.com, the Bruins added $7.8 million against the salary cap with the three trades.
B’s general manager Peter Chiarelli is set to address the media at 5:00 p.m. here at TD Garden. Until then, here are some quick reactions to the two deals.
Zanon deal: Bruins trade defenseman Steve Kampfer to Wild for defenseman Greg Zanon
Reaction: At face value, the Bruins traded a defenseman who couldn’t crack the top six for a defenseman who should end up on the second pairing with Dennis Seidenberg .
Zanon, 31, is in the last year of his contract and carries a $2.1 million cap hit. The 5-foot-11, 202-pound veteran averaged 18:37 of ice time in Minnesota this season, and last year he was second in the league with 212 blocked shots. That makes him a solid pickup, especially if he can fit well with Seidenberg for the rest of the season before Claude Julien  presumably reunites the Seidenberg-Zdeno Chara  super pairing.
Of course, if Zanon ends up playing on Seidenberg’s pairing, that would mean that Joe Corvo has lost his spot in the Bruins’ lineup (at least once Johnny Boychuk  is back in the lineup). That’s the assumption at this point, as it seemed all along that one of the Bruins’ biggest needs at the deadline was an upgrade at Corvo’s spot. Corvo, a free agent at season’s end, has been prone to bad turnovers and has not produced as much offensively as he has in seasons past with other clubs.
One stat with Zanon that sticks out: He has just 27 shots on goal in 39 games this season. By comparison, Adam McQuaid has the lowest total amongst Bruins’ regulars with 39. He’s played six more games than Zanon, but he’s also average about three less minutes per game.
As far as the compensation goes, consider this scribe somewhat surprised to see Kampfer go. The 22-year-old blue liner had been up for stretches at a time over the last two seasons. He showed promise with his speed and skills in the offensive zone, but he never got enough consecutive games this season to look quite as comfortable as he did when he was first called up by the Bruins last season.
The good news for Kampfer is that he’ll get a break from life as a seventh defenseman and actually play in Minnesota.
Mottau/Rolston deal: Bruins trade AHL defenseman Marc Cantin and forward Yannick Riendeau to Islanders for defenseman Mike Mottau and forward Brian Rolston 
Chiarelli brought a couple of players back to Boston, as Mottau played his college hockey at Boston College , while Rolston played five seasons for the Bruins after being acquired in the Ray Bourque  deal.
Mottau was recently activated off injured reserve by the Islanders, as he was out from Dec. 29 until Sunday with a concussion. In 29 games this season, the 31-year-old has two assists and a minus-10 rating. He should be an extra guy on the Bruins’ lineup.
As for Rolston, he becomes the Bruins’ lone pickup to address their injury-bitten offense. With both Nathan Horton  (concussion) and Rich Peverley  (knee) out, the 39-year-old Rolston is by no means a replacement for either, though he can handle minutes on the Bruins’ third line for the time being. He also brings a good veteran presence. From his days with the Bruins (2000-2004), only Patrice Bergeron  remains on the roster.
As NESN’s Douglas Flynn notes, Rolston’s $5.0625 million cap hit actually makes him the Bruins’ highest-paid forward, and second-highest player behind Chara ($6.9 million).
This trade lands the B’s a couple of veterans whose impact will be limited, but given the cost, it was a deal worth making. Neither Cantin nor Riendeau figure to make much of an impact at the NHL  level.
