Sure, but it's still different. The Lakers are a team that was disliked for their success, and that dislike still exists. Seeing them not do as well for a little bit doesn't suddenly erase that. I'm sure some people are happy to see the Red Wings fall out of the playoffs, but that doesn't mean any dislike they had for their success is suddenly erased. Ditto for Chicago.
That doesn't apply to Toronto. Many people here weren't even alive the last time they won a Championship. Probably yourself included, if your username is based on your DOB. There is no reason to have dislike for their past success, because it isn't relevant. Sure, the media coverage might get annoying for some, but for others it has no impact on them at all. I'm not going to that there aren't people who don't like Toronto, but to see it constantly brought up in every single poll, and used as an excuse in almost any incident where people disagree with Toronto fans is an old and tired argument. You might need to consider that people disagree because they disagree. That would allow you to actually go further into the discussions, because you aren't being paranoid that people are just hating on you. There are legitimate reasons people might think Matthews is outside the top 10 of Centers, as an example. Good reasons. You might not agree yourself, and that's your opinion, and I respect that, but constantly seeing it brought up when a vote doesn't go Toronto's way just gets ridiculous. Or when people say "Hold your horses" on Toronto's start to the season, or Matthews starting the season off as hot as he did.
Think about it, were they wrong? Toronto did slow down. Markedly. Matthews did cool off. Those arguments were made because they applied to the situation. It wasn't because people hate Toronto. It's because we've seen this type of thing before, and it consistently ends the same way.
