I honestly don't see most of these moves happening. Sheahan is not worth a second round pick at this point. Vegas will more than likely stay away from Helm. Calgary would consider the trade, but I don't think stone is the player people think he is.

Let's say Vegas takes a cheaper player, Jensen for arguments sake. Holding off on the Green trade until the deadline puts the team over the cap. There may need to be a few more creative moves if you want to 'stay competitive'
