Everyone's favorite waiver wire guy

Brian Rolston and Mike Mottau are heading to the defending champion Boston Bruins in exchange for a couple of prospects in Marc Cantin and Yannick Riendeau. Minnesota also made a swap with the Bruins, sending human puck absorber Greg Zanon to the B’s in exchange for Steve Kampfer. The needs for each side are pretty clear here as the Bruins look to add depth down the stretch while the Islanders look to stockpile useful prospects.

In Rolston the Bruins get a guy who has been in Beantown before and can play useful minutes. He’s obviously not the guy who was an all-star calibre player in Minnesota, but he can still play useful minutes in Boston’s bottom six. Mottau is a bit of a Johnny Oduya type of guy in that he is a fairly mobile guy who hasn’t been defensively steady since he departed New Jersey. Again that’s part of the system you play in and part due to injury. He should be a nice fit for Boston in a defense first role. Greg Zanon is more of the same for Boston as he is a gritty defenseman who will block a lot of shots for you. All nice additions for a Boston team that seems to have lost its way of late.

In terms of what has headed back the other way from Boston is a bit of a mixed bag. Kampfer has been trying to break into the Boston defensive corps for some time now and just hasn’t been able to hold down a spot. He’s a young guy (24) and can move the puck quite nicely. Minnesota seems to be going for a more mobile defensive corps in their own right when you look at who they shipped out in Zidlicky, Zanon and Schultz, while picking up Foster, Gilbert and Kampfer.

For the Isles, they get a couple of prospects I quite like. Marc Cantin was a solid citizen on a good St. Michael’s Majors squad in 2011 that fell just short of a Memorial Cup. He’s a steady guy who plays good sit back defense. He won’t wow you with what he does but he makes heads up plays. In Riendeau they have taken on a bit of a project player given that he is very offensively minded and not much else, but with a little work he could be a decent organizational guy for them.

Good trades for each party in this tree.
