Good return for the Hawks. I personally don't value any picks past the top-20 as all THAT valuable, though still a good return for a player who wasn't fitting the system. Ejdsell should be good.
As for the Preds, I'm perfectly fine with using a late 1st on the RFA Hartman. He'll replace Hartnell going into next season.
As mentioned, the Preds core is set for a few years now. We'll have to get Ellis under contract during next season and Josi within two seasons. Johansen, Forsberg, Arvidsson, Turris, Subban, and Ekholm are locked in for a long time. Rinne is the only wildcard as he is up at the end of next season (that $7 mil contract the Preds got trashed for doesn't look all that bad).
Future is bright in Nashville.
