Yeah that's the other thing ... the market isn't that great this year for D.
Connor Murphy isn't anywhere close to an Ekholm impact add, neither is Ristolanien. The ask for these players is likely a 1st + prospect. Then you have lesser options like Denis Savard, TJ Brodie, Jusso Valikmaki, etc.
For people saying "the market will magically open up!", no it probably won't. We're now into February this is not like US thanksgiving still, we're getting into the home stretch already, the teams in it right now will likely want to stay in.
Whereas for goaltending, Vejmelka could be available (12th best GSAA). So could Gibson (5th best for GSAA this year). So could Talbot (14th best GSAA).
There's not a lot of logic here in that a there's a D available who would move that needle more than a goalie.
