When the Pittsburgh Penguins signed Kasperi Kapanen to a 2-year contract extension it pushed the team over the salary cap. By signing Kapanen and avoiding arbitration it also opens up a second 48 hour buyout window for the team. This buyout window could prove useful as multiple NHL teams are currently trying to move salary making it exceptionally difficult to get a move done.
A buyout of Zucker would save the Penguins $3,500,000 this season, while a Pettersson buyout would save then approximately $2,500,000 this year.
