The Boston Bruins have acquired Brian Rolston and Mike Mottau from the New York Islanders in exchange for Yannick Riendeau and Marc Cantin. Rolston's days of being a factor in standard fantasy leagues are well behind him, but he will provide the Bruins with a veteran presence as they get ready for the playoffs. For the Islanders, this is a salary dump, as Rolston comes with a $5,062,500 annual cap hit.
