When Letang is healthy, Niskanen should sit in favor of Bort/Maatta on the 3rd pairing. Martin and either a forward or Letang will be on 1st PP, and Maatta/Letang will probably be the 2nd pairing.
But they probably intend to demote Maatta soon, so I don't expect to see that.
Simply put, we have way too many Dmen who need to play right now to even have Niskanen on this team. We were all happy we kept Niskanen when Letang went down, but at this point, I would rather have Depres or Maatta as the 5th D man than Niskanen. That still leaves us with Dumo in the minors, when he should be our #7D.
Scuderi Letang
Martin Orpik
Depres Bortuzzo
Maatta Dumoulin
Where is there room for Nisky and Engo? You've got 2 bottom 6 spots for 4 guys, it's a logjam without Nisky and Engo.
