Yeah I'd agree with that. Obviously all time, Detroit's biggest rivals are Chicago, Toronto, etc., but for the time period of late 90s/00s, I think Detroit-Anaheim was a pretty good rivalry, one of the better ones in the West* ... 6 playoff series in 16 years... Anaheim wasn't a real cup contender for a while (even with the 03 run, they weren't real contenders yet), and it never reached Detroit-Colorado levels of hatred, but it lasted longer, as the rivalry with Colorado pretty much ended when you beat them by 7 in game 7 in 2002. Kinda sucks that most of these rivalries are dead, but at least (for us out here) the rivalries with the other California teams have gotten better, although the rivalries between the fanbases have always been there.
*even though pretty much every western team's fanbase will claim to have had some sort of rivalry with the Wings lol
