The Pittsburgh Penguins have acquired forward Derick Brassard from the Ottawa Senators as part of a three-team trade also involving the Vegas Golden Knights, the teams announced Friday evening. Along with Brassard, Pittsburgh also receives a third round draft pick (2018) and forward prospect Vincent Dunn from the Senators as well as forward prospect Tobias Lindberg from the Golden Knights. The Senators have landed goaltending prospect Filip Gustavsson, defenceman Ian Cole, and two draft picks: a first rounder in 2018 and a third rounder in 2019, while Vegas walks away with forward Ryan Reaves and a fourth-round draft pick (2018). The full details of the transaction brought about plenty of confusion, as the league initially rejected the complicated deal before the teams reworked it. Brassard, 30, is set to become an unrestricted free agent following the 2018-19 campaign. He has a salary cap hit of $5 million but is owed only $3.5 million in actual dollars over the final two years of his contract.
