How can a team with 0 championships and only 1 trip to the championship game in its existence have haters? I think we all just mutually dislike them, much like how a lot of people that live in the Vancouver area specifically dislike the Canucks just because they're the home team.
That's a pretty illogical statement. Championships don't define whether or not a team is hated. The Packers are the most successful NFL team in history, yet I don't think they're even close to the upper tier in terms of teams that are hated.
Conversely, look at my team...the Jets, they haven't won a Superbowl since the 60s, yet were voted the most disliked team this year.
Honestly, there can be a legitimate argument to hate any NFL team in the league and it's borderline stupid to argue about it. It's a game, let's watch and enjoy. We can debate about stats, players, coaches etc. But to argue about what teams are hated and why? Kind of ridiculous.
