I think people are forgetting how effective he was in the playoffs when he was in an ultra defensive usage. And his transition ability against a team like Colorado with an aggressive forecheck. He's not necessarily a game-changer on the backend, but to compare to the center situation, he's very much a Bozak type acquisition, where it solidifies a middle 6 role and he has the ability to play in all situations. And depending on what move is made to create the space, I could easily see him being the Bozak move, with the ROR LD move coming after.
Options are:
Perunovich starts in the minors because he has 37 NHL games left before he has to be exposed to waivers.
Mikkola is exposed to waivers.
Carry 8 dmen.
Someone is moved, whether it's Scandella, Krug, Mikkola, or Perunovich.
