This is an invalid question. Obviously Suglobov is likely to be in the NHL whereas Klee will not be, but the Devils were getting rid of Suglobov regardless. You cannot evaluate prospect for veteran deals this way or else they will all look bad. The Devils are getting a better player for one not on their roster and one not in their future plans.
Who will be a better player in 5 years - Peter Forsberg or Cam Janssen?
I like the fact that even today the answer to this question is still Peter Forsberg.
