The Dumba deal isn't a trade that will "wow" anyone, but it provides the Penguins with another body for the right side of their defense and a good future asset that they don't necessarily have to retain. They are also set up to gain more future assets at next year's deadline, as Dumba is one of several players who don't have a contract beyond this season, including
Connor Clifton,
Kevin Hayes,
Anthony Mantha,
Blake Lizotte,
Noel Acciari,
Connor Dewar, and
Danton Heinen. In other words, the rebuild is proceeding as planned.
