Rangers are re-signing Ryan Bourque. In the Gordie Clark-Jeff Gorton pre-draft question and answer with Jim Cerny--Gorton brought up Bourque and the progress the team feels he has made. I don't know how much exactly this had to do with the Dorsett trade but Bourque is definitely back in the Rangers plans and he did have a really good year in Hartford. That Gorton brought him up at all unsolicited by Cerny makes me think that Bourque might even make a run at an NHL job.
Third rounder seems fair for Dorsett--bearing in mind that a 3rd rounder is probably not going to play with us for a while. The saved cap space might allow the Rangers to keep one of their UFA's however or bring in someone better.
