The Penguins have made a few significant changes to their major-league roster since being swept out of the playoffs by the New York Islanders in April. They've added forwards Dominik Kahun, Alex Galchenyuk and Brandon Tanev and traded right winger Phil Kessel and defenseman Olli Maatta, while Garrett Wilson went to Toronto as a free agent.
What's more, it's almost guaranteed that at least one more move is coming, because Jim Rutherford says the Penguins have to clear some salary-cap space before re-signing defenseman Marcus Pettersson.
