Some old timers like me grew up following the Kings, and that was our first taste of hockey fandom. But it was always a lukewarm thing, because they were so weirdly and ineptly run. Even with the Gretz trade, sure it was good ... but also you were expected to now root for a bunch of hated ex-Oilers? And they kept bringing in more? Awkward as hell. And the ineptitude didn't really stop, they never really built the right kind of team back then, and kind of squandered the Gretz years.
The Ducks were the first time I had a chance to root for a team from day one. Literally from that first night with Wild Wing catching fire and the Red Wings obliterating the team on the ice. It's different than following a team who had decades of history from before I was even born, I suffered through EVERYTHING with this team. Made '03 and '07 truly wonderful experiences.
But it also does mean I don't really HATE the Kings either. I just don't root for them.
And the older I get, the less I care about rooting against anyone really. Once my teams are eliminated, I just want good games/series. In my ideal world, we get 15 game 7 OTs this year. At this point the only team I want to see utterly fail is the Hawks, and only until all those involved in the abuse scandal are dead and gone.
