Objectively... Quinn Hughes is still 2 full seasons away from unrestricted free agency; and has absolutely no trade protection.
The Devils may not be the highest bidder for his services on the trade market, but to think that Quinn Hughes couldn't command a reasonable ransom for 2 years of his servies at $7.85m is unrealistic.
Ultimately, Vancouver has no obligation to "do right by" Quinn and trade him to NJ; and once another team gets him, you never know maybe he does sign there long term. He's obviously the Captain of the Canucks, but things aren't exactly all peaches and roses over there.
