I am happy to see they are looking for another bargain D-man but I still don't quite see how a new player would fit in other than as insurance against injury (which would of course be a fine enough addition). I think there are probably a few players of Kempny's caliber out there but it's going to be up to BMac to find a guy off the radar because guys like Jensen who were once off the radar suddenly are now on everyone's radar and their value has increased around the league.
While BMac could make a significant move and deal someone currently in the lineup I don't really see that happening. In which case, who would a new defenseman replace? Carlson clearly isn't going anywhere, Kempny's having a rough go but I doubt they give up on him after last postseason and a pretty good first half of this season, Djoos is only getting better, Orpik brings the intangibles and PKing that aren't going to be replaced, and I doubt they move on from Niskanen since he's a RHD on a team and organization that has zero quality RHD behind him.
Orlov being shipped out would be the only drastic move I could remotely see happening if they aren't convinced he's going to be a long-term fit due to his contract, but again, despite a poor season-to-date is that really likely to happen given his ascension to shutdown duties in a Cup-winning run? That seems much more likely to be an offseason move if it comes to it.
I also don't see much sense is getting rid of Burakovsky unless it's someone like Mark Stone or another top-tier talent coming back, but even then you would have to demote Oshie, Wilson, or Vrana and I'm not sure how well that would go in the locker room.
As I said earlier my prediction is still that they will stand pat for the most part and players are just going to have to play better (and coaches coach better).
