I dont like idea to trade anyone for picks, unless first rounds. It`s better to trade for prospects. Atleast they are closer to NHL.
Or trade for picks with plan to trade picks as a part of big trade for much better player.
Here is the thing a prospect being traded for a rental…they are likely a prospect that is going to bust. Teams know their players better than other teams and they probably know better who is more likely to make it than not.
