So Faulk, Parayko, Krug, Mikkola seem to be our current top 4. So whoever we get needs to be better than Walman and Bortuzzo in order for it to be an upgrade. On the left side we could even go after a #1 left D then slide Krug and Mikkola down to the #2/3 pair. I really think we need an upgrade over Bortuzzo as well.
Scandella should not play anymore unless there's an injury and ideally we would find someone to take on his contract, either in a separate trade or included in this one. I'll always take Walman over Scandella in the lineup, left or right side.
