Calgary can't afford that

Only on capfriendly does a in his prime offensive star get less of a return than a rental goalie.

They're both UFAs, there's retention on Hellebyuck but not Nylander and the Jets are taking Murray in this scenario, that's probably the reason for the difference.
Also Zadorov, Dube, Coronato would have more value then Timmins and Robertson so thats a factor as well.
