If it's been made clear that Quinn wants to play with his brothers, then he's as good as gone. They need to trade him this summer for the best available package that a contender is going to offer up to get Q. Hughes on a great value contract for two seasons. Q. Hughes has zero trade protection, so he can go wherever he is told.
Canucks cannot mess around. Hoping around to re-sign him isn't going to happen. Hoping the team bounces back in a major way and is competing for the Cup next year isn't realistic either. They aren't going to bring two Hughes brothers in from New Jersey when New Jersey can wait around to sign Quinn as a UFA. Two years means he's still worth a premium package, but loses value every day you get closer to July 1, 2027.
