I keep hearing Cam Talbot's name out there as a goalie other teams want. NYR probably wants to keep him but I've heard numerous reports that they wouldnt be against a trade if the return was right.
Martin Jones is another backup that LOTS of teams covet. Again the asking price will be very high I think.
For an off the wall suggestion, Jon Gillies in CGY. He's seen to be well along is his development and could be NHL ready soon. I dont know if CGY would rush him or make room for him, but if he was in the NHL he's got the talent to win the job.
