^He's a pompous, self-absorbed asshole who forced his way out of town by tying the organization's hands behind its back. If he'd left under different terms, and/or was more likeable, I don't think there'd be as much vitriol.
No. But I can understand the majority of fans being upset at him wanting out. But booing Kesler = Booing the Canucks, since they created the environment for him to even want out in the first place.
