Here’s Fluto’s take, seems the Athletic has all the teams Pierre mentioned do a “what if” type piece.

He thinks Hall would cost Vaakanainen, Lauko and 2020 1st.
I’d be more willing to include Vaakanainen if we knew what the future holds for Krug. If he’s in the cards past this season, then I can see a plausible scenario where trading Vaakanainen made some sense. They’d have Krug, Grzelyck (RFA), Moore under control through next season, plus Chara if he is still up for it. Zboril and Lauzon need new deals but would be cheap depth. Of course under this scenario Krug is retained under a large extension so Hall would become a pure rental and trading Vaakanainen for 25 games plus a playoff run of Hall is too rich for my blood.
