Michael Del Zotto is a bottom pairing defenseman that the Canucks have given top-4 minutes to, so a team who is looking to make a cup run can acquire a guy who has seen plenty of playing time the past couple of seasons and can play in all situations.
It's crazy how Canucks fans love Biega as a bottom pairing defenseman, but don't appreciate Del Zotto because of his salary, even though the Canucks have had almost unlimited cap space for the past five years. Del Zotto is objectively better than Biega, who will also likely be moved for a late pick. With the lack of rentals available, I imagine both players will have interest from multiple teams.
The Canucks will also probably move Hutton who I know on good authority Green doesn't like. This is a good year to acquire some late picks and maybe move up in the draft.
