That's what teams do when they take a major hit on depth talent.
That is why the Rangers traded Gaborik (aside from feud with Torts). They got depth for 1 player. The following year they went to the cup with a savvy trade and an injured Nash. It is possible to survive and improve after a trade like this.
The Rangers had Nash. You don't need 2 40 goal scorers if you have no depth. Dumping Nash makes absolutely no sense.
