I don't see it. Anaheim and Minnesota will lose one of those defenseman. They certainly may have a deal in place to protect one of them but not both.
They are not on the same team so I see no reason for there to be a connection between the two teams.
I'm assuming he's referring to the tandem each team exposed. Manson/Vatanen for Anaheim, and Dumba/Scandella for Minnesota. A deal from each team likely protects one player, but not both.
