The really obvious one is Grubauer, whose struggles seem to sap the spirit from the team. You get lucky with a .910 goalie in his place and a lot can change (e.g. what the Wild did with Filip Gustavsson). Gru definitely needs to be bought out or buried.
For the other three, with the way the cap is going up, every UFA we could reliably replace those guys with will be costly. I think you do retained deals if you can, when you feel like they're hurting the team. But I've gone back and forth on all of them whether they're actually that bad. Like ECH was saying that Oleksiak has looked better since his game 1 disaster (I haven't watched enough to verify myself, but his game log and goals results look good). Bura and Schwartz have been up and down for so long that I don't know what to expect. I'm pretty sure they'll be injured and suck for part of the time, but they might also have some really good stretches. I think Oleksiak can get traded this Spring but Bura and Schwartz can't without heavy retention or us paying, and again I'm not sure it's worth it where we are at as a non-contender.
I know that isn't the most encouraging thing to say about how we'll have a 2025-26 turnaround, but I don't see a quick path here. I think we'll probably be in the bottom half of the conference this year and next. With Gourde and Tanev aging out and seemingly Bjorkstrand on the outs I don't think we'll have a forecheck advantage anymore, it already looks gone. Those guys were always the first thing I looked at in our lineup and thought "we can win those minutes". When we were good it was largely because of them.
