Personally I'd target Kulich. If you consider that Thompson and Cozens are their top two guys, Krebs better fits the 3C role (because of his defense and tenacity) than Kulich does so I'd imagine they'd keep him. I doubt they'd want wingers back in a trade (because they can just flex centers to the wing) so you're going to have to trade defense. The only defenders we have that are on Kulich's level are Edvinsson (untouchable probably) or Wallinder. I'd hate to see Wallinder go, he's played really well and is going to be really good. BUT we're deep on LD and we REALLY need a top center prospect to go along with Kasper. So I'd start with Wallinder for Kulich straight up (which is close to fair) and be willing to add a mid-round pick if necessary.
