Adam Fox was last guy I can remember who was traded to Carolina and then flipped for a 2nd and conditional 3rd after it was reported he only wanted to sign with NYR. He was a prospect tho.I can't see Carolina moving Rantanen unless they get something back that helps them right now. They gave up a very good player to get him and are trying to win a Cup. If he was available, I don't think the Oil have the assets to get something like that done.
Maybe 1st and conditional 2nd will get the job done?
