I also think that in general SY doesn't want to deplete his prospect pool too much. Replacing guys like Fabbri with guys like Mazur (on an entry level deal) is going to create a competitive advantage for this team in a few years. I doubt SY is in a rush to trade away a bunch of cheap NHL caliber talent for a rental right now. Maybe in a year or two when we're really close to competing for a Cup.
I can see our 2nd/3rd round picks and B-level prospects in play, but outside of Berggren (who I think it probably gone at the deadline) I don't see him moving any prospects of any value (Mazur, Kasper, Edvinsson, Danielson, Cossa). Maybe Johansson, Wallinder, Lombardi are in play for the right deals, but I don't see them being moved for the sake of a middle six rental or something like that. They've got more value to our team as cheap replacements for our depth guys.
