The thing is, what do the Rangers have to give up for an upgrade?
They're pretty much done with giving up high draft picks. Eminger, Boyle, Pyatt, Powe and Gilroy have little value. How are they going to get an upgrade for those guys? I can see a team taking Pyatt for a solid 5th/6th defenseman thinking Pyatt can score 30 points again.
This team is still a Cup contender. If they're looking to upgrade on the blueline, no way do they weaken their top 6 for an upgrade.
The only thing I see is the Rangers giving up prospects. They can do that, but how are they going to restock? Granted, we do have young guys like Kreider, Hagelin, Stepan, McD, Staal, etc...
