I reserve the word “hate” for things in the world that really deserve it, and sports teams – even rivals of my favorite teams – don’t come even close to that level. Similarly, I don’t think that jealousy really crosses my mind, either, at least not anymore.
When I was younger (in the 1970s and 1980s), being a Packer fan was often not fun, as the team was consistently pretty bad, and I suppose that, at that time, I probably had some jealousy over teams that were successful. (And, yes, I’m fully aware that the shoe has been on the other foot for much of the past 25 years.)
I’ll say that I get ***tired ***of seeing a particular team consistently winning its league’s championship. I can respect the skill (likely top-to-bottom in an organization) that goes into such a run of success, but if it’s not “my team,” after a certain point, I just want to see another team winning (even better if it’s my preferred team).
If my team isn’t going to have a chance to win the title in a particular season, I’d rather see a team win that hasn’t won in a long time (if ever) – so, in football, for example, I’d love to see Browns or Lions fans be able to finally enjoy a championship, rather than yet another Patriots win.
One other thing that can rub me the wrong way is that some (certainly not all) fans of teams which have been consistently successful can come across as feeling that championships are some sort of expectation or birthright – I used to see that with some Cowboys fans in the 1970s, with some Yankees fans at various points, and now with some Patriots fans.
(Also, regarding the Blackhawks: yes, they had a very nice run recently of, what, three championships in six or seven years? Longtime hockey fans will also recognize that the Blackhawks had a multi-decade run of being mediocre-to-terrible, and a long-suffering fan base which finally got to enjoy that run of success.)
